Description

Technical Field

[0001] The invention relates to an automatic feeding and discharging mechanism of sewing equipment. Background Art

[0002] At present, sewing processing sites generally have multiple sewing processing stations. During the processing, people need to deliver the materials (raw materials) required for processing to each station and take away the materials after processing in time. However, due to the lack of material entry and exit mechanisms connected to each station in the existing technology, or the processing personnel manually carry the materials by themselves, the distribution of the entire material is relatively chaotic, which affects the production efficiency. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides an automatic material feeding and discharging mechanism for sewing equipment, which facilitates processing personnel to promptly obtain materials required for processing and to promptly deliver the processed materials, making the entire material distribution process more standardized and orderly, thereby effectively improving production efficiency.

[0004] To achieve the above-mentioned purpose, the present invention provides an automatic feeding and discharging mechanism of a sewing equipment, including a material rack arranged beside the sewing machine and a material box for placing materials, the material rack including a frame and a platform fixedly arranged on the frame, an ascending channel for the material box to ascend and a descending channel for the material box to descend are formed on the frame, the lower port of the ascending channel is connected to the material box feeding device, and the lower port of the descending channel is connected to the material box feeding device, a lifting device for lifting the material box from its lower port to the upper port is arranged in the ascending channel, and a descending device for moving the material box from its upper port to the lower port is arranged in the descending channel, a first area connected to the upper port of the ascending channel and a second area connected to the upper port of the descending channel are correspondingly formed on the platform, and a pushing device for pushing the material box at the upper port of the ascending channel to the first area of ​​the platform is arranged on the frame.

[0005] The beneficial effect of the present invention is that: by adopting the above structure, the material is placed in the material box, and at the same time, multiple material boxes can be stacked together, and then distributed to the lower port of the ascending channel through the material box feeding device, the material box feeding device can be a conveyor belt, an automatic distribution trolley (distribution robot), or a cart, etc. The multiple stacked material boxes are lifted upward by the lifting device in the ascending channel, and the material box feeding device can return to perform additional distribution. When the top material box reaches the upper port of the ascending channel, it is pushed to the first area of ​​the platform under the action of the pushing device. When the processing personnel take the material from the material box, they can push the material box from the first area to the second area, and put it into the material box again after the material processing is completed. After that, the processing personnel push the material box on the second area into the upper port of the descending channel, and the material box is transferred from its upper port to the lower port through the descending device, that is, the material box is placed on the material box delivery device, and finally delivered by the material box delivery device. The material box delivery device can also be a conveyor belt, an automatic distribution trolley (distribution robot), or a cart, etc. In summary, the present invention facilitates processing personnel to timely obtain materials required for processing and to timely deliver materials after processing, and the entire material distribution process is more standardized and orderly, thereby effectively improving production efficiency. In addition, the present invention can also stack multiple material boxes together and deliver them in or out at one time, thereby further improving production efficiency.

[0006] The present invention can be further configured such that guardrails are provided on three sides of the platform, and the guardrails on the three sides form a U-shaped structure and include the first and second areas therein, and the remaining side is open, and the opening is located on the side away from the sewing machine, and the ascending channel and the descending channel are located side by side on the side of the platform where the opening is provided.

[0007] By setting the guardrail, the material box can be effectively prevented from falling when it moves on the platform. At the same time, the guardrail is set in this way, and it also plays a guiding role and a limiting role in the feeding, sending and movement of the material box.

[0008] The present invention can be further configured such that each side guardrail includes a connecting rod, and the connecting rod has a plurality of fixed blocks linearly distributed along its length direction, and a screw sleeve is fixed at a position corresponding to each fixed block on the platform, and the fixed block is pressed against the screw sleeve and fixed by bolts. With the above configuration, the structure is simple and reliable, and it is easy to disassemble and assemble.

[0009] The present invention can be further configured to have a plurality of bull's eye bearings distributed on the area of ​​the platform located within the guardrail. The bull's eye bearings are arranged to further facilitate the movement of the material box on the platform.

[0010] The present invention can be further configured as follows: the lifting device includes a lifting motor and two groups of lifting components, the two groups of lifting components are arranged on both sides of the ascending channel, and form a transmission match with the lifting motor; the descending device includes a descending motor and two groups of descending components, the two groups of descending components are arranged on both sides of the descending channel, and form a transmission match with the descending motor; each group of lifting components and each group of descending components include upper and lower rotating shafts and sprocket chains for transmission connection between the upper and lower rotating shafts; the upper and lower rotating shafts are rotatably installed on the frame and are distributed up and down; L-shaped plates for supporting the bottom of the material box are symmetrically arranged on the chains on both sides.

[0011] With the above structure, the material box enters the ascending channel, and the L-shaped plates on both sides support the bottom of the material box from both sides respectively. Under the action of the lifting motor, the L-shaped plates are transported together with the chain, thereby driving the material box to rise; similarly, after the material box enters the descending channel, it is placed on the L-shaped plates on both sides. Under the action of the descending motor, the L-shaped plates are transported together with the chain, thereby driving the material box to descend.

[0012] The present invention can be further configured such that a rigid limit bar is vertically arranged between the upper and lower rotating shafts, the rigid limit bar is fixed to the frame through a crossbeam, and the chain abuts against the rigid limit bar. With the above structure, by abutting the chain against the rigid limit bar for transmission, it is possible to effectively avoid the situation where the chain is partially sunken or wrinkled, so that the chain always remains straight during the transmission process, thereby effectively ensuring the stable and reliable transmission of the material box.

[0013] The present invention can be further configured such that the pushing device includes a slide rail, a sliding seat, and a pushing block. The slide rail is transversely fixed on the frame and is correspondingly located above the platform. The sliding seat is slidably connected to the slide rail and is connected to a transverse driving cylinder that drives it to slide transversely. The pushing block is connected to a longitudinal driving cylinder that drives it to rise and fall, and the longitudinal driving cylinder is installed on the sliding seat.

[0014] With the above structure, when the material box reaches the upper port of the ascending channel, the sliding seat slides to the rear of the material box under the action of the transverse driving cylinder, and then the pushing block descends under the action of the longitudinal driving cylinder. After that, the transverse driving cylinder continues to work, thereby driving the longitudinal driving cylinder and the pushing block to move transversely together, and then pushing the material box onto the platform. After completion, the pushing block rises under the action of the longitudinal driving cylinder, and then moves transversely under the action of the transverse driving cylinder, and returns to the initial position for the next push.

[0015] The present invention can be further configured such that two rows of supporting feet are provided at the bottom of the material box, each row of supporting feet includes at least two linearly arranged protrusions, and two linear grooves are correspondingly opened on the top of the material box, and when stacked, the two rows of supporting feet of the upper material box respectively enter the two linear grooves of the lower material box, and the two side walls of the linear groove form abutment with the supporting feet entering therein.

[0016] Through the cooperation of the above structure, multiple material boxes can be stacked together more stably and reliably.

[0017] The present invention can be further configured such that both ends of the linear groove are provided with through openings for the support legs to slide out or in, and the through openings are tapered structures that are wide outside and narrow inside. This configuration allows the upper and lower material boxes to slide in or out from two directions, and such sliding cooperation also guides the material box in and out of the channel.

[0029] With the above structure, the material is placed in the material box 3, and multiple material boxes 3 can also be stacked together, and then delivered to the lower end of the ascending channel 23 through the material box feeding device 4. The material box feeding device 4 can be a conveyor belt, an automatic delivery trolley (delivery robot), or a cart, etc. Multiple stacked material boxes 3 are lifted upward in the ascending channel 23 by the lifting device, and the material box feeding device 4 can return for further delivery. When the top material box 3 reaches the upper end of the ascending channel 23, it is pushed to the first area 221 of the platform under the action of the pushing device 6. When the processing personnel take the material from the material box 3, they can push the material box 3 from the first area 221 to the second area 222. After the material processing is completed, it is put into the material box 3 again. After that, the processing personnel push the material box 3 on the second area 222 into the upper end of the descending channel 24, and transfer the material box 3 from its upper end to the lower end through the descending device, that is, put the material box 3 down to the material box delivery device 5, and finally send it out by the material box delivery device 5. The material box delivery device 5 can also be a conveyor belt, an automatic delivery trolley (delivery robot), or a cart. In summary, the present invention facilitates the processing personnel to take the materials required for processing in time and send out the materials after processing in time, and the entire material delivery process is more standardized and orderly, thereby effectively improving production efficiency. In addition, the present invention can also stack multiple material boxes together and send them in or out at one time, thereby further improving production efficiency.

[0030] Guardrails 7 are provided on three sides of the platform 22, and the three side guardrails form a U-shaped structure and include the first and second areas therein, and the remaining side is provided with an opening 223, and the opening is located on the side away from the sewing machine 1, and the ascending channel 23 and the descending channel 24 are located side by side on the side of the platform 22 where the opening 223 is provided.

[0031] By providing the guardrail 7, the material box 3 can be effectively prevented from falling when moving on the platform 22. At the same time, the guardrail 7 is provided in this way, and also plays a guiding role and a limiting role in the feeding, sending and movement of the material box 3.

[0032] Each side guardrail 7 includes a connecting rod 71, and the connecting rod 71 has a plurality of fixed blocks 72 linearly distributed along the length direction thereof. A screw sleeve 73 is fixed to the position corresponding to each fixed block 72 on the platform 22, and the fixed block 72 is pressed against the screw sleeve 73 and is locked and fixed by bolts 74. With the above arrangement, the structure is simple and reliable, and it is easy to assemble and disassemble.

[0033] A plurality of bull's eye bearings 224 are distributed on the platform 22 in the area within the guardrail 7. The bull's eye bearings 224 are provided to facilitate the movement of the material box 3 on the platform 22.

[0034] The lifting device includes a lifting motor 8 and two groups of lifting components 9, the two groups of lifting components 9 are arranged on both sides of the ascending channel 23, and form a transmission match with the lifting motor 8. The descending device includes a descending motor 10 and two groups of descending components 11, the two groups of descending components 11 are arranged on both sides of the descending channel 24, and form a transmission match with the descending motor 10. Each group of lifting components 9 and each group of descending components 11 include an upper rotating shaft 91, a lower rotating shaft 92 and a sprocket 93 and a chain 94 for connecting the upper and lower rotating shafts. The upper and lower rotating shafts are rotatably installed on the frame 21 and are distributed up and down. The chains 94 on both sides are symmetrically provided with L-shaped plates 95 for supporting the bottom of the material box 3.

[0035] With the above structure, the material box 3 enters the ascending channel 23, and the L-shaped plates 95 on both sides respectively hold the bottom of the material box 3 from both sides. Under the action of the lifting motor 8, the L-shaped plates 95 are transported together with the chain 94, thereby driving the material box 3 to rise; similarly, after the material box 3 enters the descending channel 24, it is placed on the L-shaped plates 95 on both sides. Under the action of the descending motor 10, the L-shaped plates 95 are transported together with the chain 94, thereby driving the material box 3 to descend. In addition, a baffle 25 is provided on the other side of the descending channel 24 relative to the platform 22, so as to limit the material box 3 pushed into the descending channel 24 by the platform 22.

[0036] A rigid limit bar 96 is vertically arranged between the upper and lower rotating shafts, and the rigid limit bar 96 is fixed to the frame 21 through a crossbeam 97, and the chain 94 abuts against the rigid limit bar 96. With the above structure, by abutting the chain 94 against the rigid limit bar 96 for transmission, it is possible to effectively avoid partial depression or wrinkling of the chain 94, so that the chain 94 always remains straight during the transmission process, thereby effectively ensuring stable and reliable transmission of the material box 3.

[0037] The pushing device 6 includes a slide rail 61, a sliding seat 62, and a pushing block 63. The slide rail 61 is transversely fixed on the frame 21 and is correspondingly located above the platform 22. The sliding seat 62 is slidably connected to the slide rail 61 and is connected to a transverse driving cylinder 64 that drives it to slide transversely. The pushing block 63 is connected to a longitudinal driving cylinder 65 that drives it to rise and fall, and the longitudinal driving cylinder 65 is installed on the sliding seat 62.

[0038] With the above structure, when the material box 3 reaches the upper port of the ascending channel 23, the sliding seat 62 slides to the rear of the material box 3 under the action of the transverse driving cylinder 64, and then the pushing block 63 descends under the action of the longitudinal driving cylinder 65. After that, the transverse driving cylinder 64 continues to work, thereby driving the longitudinal driving cylinder 65 and the pushing block 63 to move transversely together, and then push the material box 3 onto the platform 22. After completion, the pushing block 63 rises under the action of the longitudinal driving cylinder 65, and then moves transversely under the action of the transverse driving cylinder 64, and returns to the initial position for the next push.

[0039] Two rows of supporting feet 31 are arranged at the bottom of the material box 3, and each row of supporting feet 31 includes at least two linearly arranged protrusions. Two linear grooves 32 are correspondingly opened on the top of the material box 3, and when stacked, the two rows of supporting feet 31 of the upper material box 3 respectively enter the two linear grooves 32 of the lower material box 3, and the two side walls of the linear grooves 32 form abutment with the supporting feet 31 entering therein.

[0040] Through the cooperation of the above structure, multiple material boxes 3 can be stacked together more stably and reliably.

[0041] Both ends of the linear groove 32 are provided with through openings 33 for the support legs 31 to slide in or out, and the through openings 33 are tapered structures that are wide outside and narrow inside. This arrangement allows the upper and lower material boxes 3 to slide in or out from two directions, and such sliding cooperation also guides the material box 3 in and out of the channel (the ascending channel 23 and the descending channel 24).
