As shown in fig. 1, an embodiment relates to a sewing device, which includes a feeding device 10, a feeding device 20, and a sewing machine 30, wherein the feeding device 10 is used for feeding a material 40, and the feeding device 20 is used for feeding the material 40 in the feeding device 10 to the sewing machine 30, so that the sewing machine 30 performs sewing.

Further, the number of the sewing machines 30 is plural, the plurality of sewing machines 30 are arranged in parallel, and the feeder 20 can feed the material 40 in the feeder 10 to the plurality of sewing machines 30, respectively. Of course, in some sewing processes, the feeding device 20 may feed the material 40 in the feeding device 10 to only one sewing machine 30.

Specifically, in the present embodiment, the sewing machines 30 are two.

According to the sewing equipment, the feeding of the plurality of sewing machines 30 is realized through the feeding device 20, the feeding operation of the plurality of sewing machines 30 can be realized by one person, and the production efficiency can be effectively improved.

In addition, because the plurality of material limiting units 122 are arranged on the carrier 121 of the feeding device 10, when one material limiting unit 122 is located at the feeding level, a worker can add the material 40 into the other material limiting units 122, and after the material 40 in the material limiting unit 122 located at the feeding level is lifted by the lifting mechanism 13 and is completely taken away, the other material limiting units 122 can be immediately moved to the feeding level, so as to ensure that the feeding device 10 can continuously feed materials, and the working efficiency is high.

As shown in fig. 4, in one embodiment, the material containing mechanism 12 further includes a driving source 123, the driving source 123 is drivingly connected to the carrier 121, and the driving source 123 can drive the carrier 121 to reciprocate, so that each material position limiting unit 122 can move to and from the loading position and the loading position. Thus, after all the materials 40 in the material limiting unit 122 at the loading level are loaded, the material limiting unit 122 can also return to the loading level under the action of the driving source 123 to wait for the workers to load materials. Moreover, after the material limiting unit 122 at the charging position is charged, the material limiting unit 122 can also move to the charging position under the action of the driving source 123.

It should be noted that, regarding the position of the loading device 10 shown in fig. 3, the left material limiting unit 122 is located at the loading position, the right material limiting unit 122 is located at the loading position, and when the right material limiting unit 122 moves to the left to the loading position, the left material limiting unit 122 moves to the left to the loading position.

As shown in fig. 4, a cross rail 124 is further provided on the mounting frame 11, and the carrier 121 is movably disposed on the cross rail 124. The cross rails 124 are used to provide a guiding function for the carrier 121, improving the accuracy of the moving direction of the carrier 121.

Referring to fig. 3 and fig. 6, in one embodiment, the material limiting unit 122 includes a plurality of limiting members disposed on the carrier 121 at intervals, a material accommodating area 122a is defined by the limiting members, and the material 40 is configured to be stacked in the material accommodating area 122 a.

Specifically, the limiting members are vertically arranged limiting plates, the number of the limiting members of each material limiting unit 122 is four, the four limiting members are arranged in a surrounding manner, and the material accommodating area 122a is formed in the middle of the four limiting members.

Further, in each material limiting unit 122, two of the limiting members are first limiting members 1221, the other two of the limiting members are second limiting members 1222, the two first limiting members 1221 are disposed at intervals along the transverse direction, the two second limiting members 1222 are also disposed at intervals along the transverse direction, and the two second limiting members 1222 are located at one side of the two first limiting members 1221 closer to the lifting mechanism 13 along the longitudinal direction.

Further, the second position-limiting member 1222 is disposed on the carrier 121 in a position-adjustable manner. Thus, the position of the second position-limiting member 1222 can be changed to accommodate different sizes of the materials 40.

Specifically, the bearing member 121 is provided with a sliding rail 1223, the sliding rail 1223 is connected with a sliding base 1224, and the second limiting member 1222 is disposed on the sliding base 1224, so that by moving the sliding base 1224, the position of the second limiting member 1222 can be changed. After the position of the second position-limiting member 1222 is adjusted, the sliding base 1224 and the supporting member 121 may be fixed by a bolt, so as to prevent the sliding base 1224 from sliding freely.

As shown in fig. 4 to 6, in one embodiment, the carrier 121 is provided with a plurality of avoidance ports 1211, the avoidance ports 1211 are located below the material limiting units 122 in a one-to-one correspondence manner, and each material limiting unit 122 is further provided with a vertical avoidance channel 122 b; the lifting mechanism 13 includes a lifting driving assembly 131 arranged on the mounting frame 11 and a lifting member 132 in driving connection with the lifting driving assembly 131, the lifting member 132 can pass through an avoidance port 1211 located below the material limiting unit 122 at the loading level under the action of the lifting driving assembly 131, and the lifting member 132 can be lifted through an avoidance channel 122b of the material limiting unit 122 at the loading level under the action of the lifting driving assembly 131.

The avoidance port 1211 and the avoidance channel 122b mainly provide an avoidance function for the movement of the lifting member 132. Specifically, after the material limiting unit 122 loaded with the material 40 moves to the upper level, the lifting driving assembly 131 can drive the lifting member 132 to lift the material 40 from the bottom of the material limiting unit 122 through the avoiding opening 1211, and then lift the material 40 along the avoiding channel 122b, so as to sequentially transport all the material 40 lifted by the lifting member 132 to the position to be taken. Of course, when all the material 40 on the lifting member 132 is removed, the lifting member 132 can also be lowered under the evasion opening 1211 by the lifting driving assembly 131 to wait for another material limiting unit 122 to move to the upper level.

Specifically, the escape channel 122b of each material limiting unit 122 is formed between two second limiting members 1222 of the material limiting unit 122.

It should be noted that the lifting member 132 can move up and down through the avoidance opening 1211, the width of the avoidance opening 1211 is smaller than the width of the material 40, and the lowest material 40 located in the material limiting unit 122 can contact with the bearing member 121 and is supported by the bearing member 121.

As shown in fig. 5, in one embodiment, the lifting driving assembly 131 includes a motor 1311, a screw 1312 drivingly connected to the motor 1311, and a nut 1313 disposed on the screw 1312, and the lifting member 132 is connected to the nut 1313.

In the case of the loading apparatus 10 shown in fig. 4, the position of the uppermost sheet of material 40 lifted by the lifting member 132 is to be taken.

As shown in fig. 3 to 6, when the feeding device 10 is in use, the material limiting unit 122 loaded with the material 40 can be moved to the loading position by the driving source 123, and at this time, the lifting driving assembly 131 can drive the lifting member 132 to ascend, so that the lifting member 132 lifts all the material 40 in the material limiting unit 122 located at the loading position; when the uppermost material 40 of all the lifted materials 40 moves to the position to be taken, the piece of material 40 is detected by the material detection part, the lifting driving component 131 stops acting, and the uppermost material 40 is waited to be taken; when the uppermost material 40 is taken away, the material detection member detects that the material 40 is taken away, and then the lifting driving assembly 131 drives the lifting member 132 to ascend; when the uppermost material 40 of the remaining materials 40 moves to the position to be taken, the lifting driving assembly 131 stops to wait for the material 40 to be taken after the material 40 is detected by the material detecting member; this is repeated until all of the material 40 on the lifting member 132 has been removed. After all the materials 40 are taken out, the material detection part cannot detect the materials 40 any more, and then the lifting driving component 131 drives the lifting part 132 to move to the position below the material limiting unit 122; then the driving source 123 drives another material limiting unit 122 filled with the material 40 to move to the upper material level, and the lifting mechanism 13 enters the aforementioned working state again. In addition, the material limiting unit 122, which has taken out the material 40, may be manually put in the material 40 by a worker.

As shown in fig. 3, in one embodiment, the bottom of the mounting frame 11 is provided with rollers 111, so that the movement of the whole feeding device 10 can be facilitated.

Further, a rear stopper 322322 is attached to the intermediate presser 321317. In this way, when the second elevation driving member 322321 drives the fourth installation body 32236 to ascend and descend, the middle material pressing member 321317 can drive the rear limiting member 322322 to ascend and descend.

Specifically, the middle presser 321317 includes a connection part 3223321 connected to the fourth mounting body 32236 and a presser 3223322 connected to the connection part 3223321, and the rear stopper 322322 is connected to the connection part 3223321.

In one embodiment, the bottom of the middle press 321317 is curved. So, can adapt to curved material 40, middle pressing material 321317 can avoid material 40 to warp on the one hand when pushing down material 40, and on the other hand can provide certain pressure for material 40, avoids material 40 to produce between removal in-process and middle pressing material 321317 and becomes flexible.

Further, the intermediate nip 321317 includes an elastic nip for contact with the material 40. Like this, when material 40 is pushed down to middle pressure material piece 321317, be by the contact of elasticity pressure material portion with material 40, and elasticity pressure material portion has the cushioning effect, can avoid material 40 to be pressed the deformation to a certain extent.

Specifically, the elastic nip is a rubber pad disposed at the bottommost portion of the intermediate nip 321317.

With reference to fig. 1 to 20, the operation principle of the sewing machine is as follows:

the material limiting unit 122 loaded with the material 40 can move to the loading level under the action of the driving source 123, and at this time, the lifting driving assembly 131 can drive the lifting piece 132 to ascend, so that the lifting piece 132 lifts all the material 40 in the material limiting unit 122 at the loading level; when the uppermost material 40 of all the lifted materials 40 moves to the position to be taken, the piece of material 40 is detected by the material detection part, the lifting driving component 131 stops acting, and the uppermost material 40 is waited to be taken; when the uppermost material 40 is taken away, the material detection member detects that the material 40 is taken away, and then the lifting driving assembly 131 drives the lifting member 132 to ascend; when the uppermost material 40 of the remaining materials 40 moves to the position to be taken, the lifting driving assembly 131 stops to wait for the material 40 to be taken after the material 40 is detected by the material detecting member; this is repeated until all of the material 40 on the lifting member 132 has been removed. After all the materials 40 are taken out, the material detection part cannot detect the materials 40 any more, and then the lifting driving component 131 drives the lifting part 132 to move to the position below the material limiting unit 122; then the driving source 123 drives another material limiting unit 122 filled with the material 40 to move to the upper material level, and the lifting mechanism 13 enters the aforementioned working state again. In addition, the material limiting unit 122, which has taken out the material 40, may be manually put in the material 40 by a worker.

The material extraction mechanism 22 is capable of grasping the material 40 at the ready position when in the extraction position. Specifically, when the material taking mechanism 22 is located at the material taking position, firstly, after the first driving member 2221 drives the material taking member 2222 to move downwards, the material taking member 2222 grabs the material 40; then the second driving member 2231 drives the first corrective member 2232 and the second corrective member 2233 to descend, so that the first corrective member 22321 and the second corrective member 22331 contact the material 40, and the accuracy of the posture of the material 40 is maintained; then the first driving part 2221 and the second driving part 2231 simultaneously drive the material taking part 2222, the first correcting part 2232 and the second correcting part 2233 to ascend; then, the feeding driving part 23 drives the whole material taking mechanism 22 to move to the first material placing position or the second material placing position; then the first driving part 2221 and the second driving part 2231 simultaneously drive the material taking part 2222, the first correcting part 2232 and the second correcting part 2233 to descend; then the material 40 is released by taking the material 2222 to place the material 40 on the bearing part 32111; then the first driving part 2221 and the second driving part 2231 simultaneously drive the material taking part 2222, the first correcting part 2232 and the second correcting part 2233 to ascend; finally, the feeding driving member 23 drives the whole material taking mechanism 22 to move to the material taking position.

When the material 40 is placed onto the bearing portion 32111 from above under the action of the feeding device 20, at this time, the material 40 is located at an initial pushing position, then the deflection driving member 321314 drives the material pressing member 321317 to rotate above the material 40, then the material pressing driving member 321312 drives the material pressing member 321317 to press the material 40, and then the first pushing driving member 32132 drives the material pressing member 321317 to push the material 40, so that the material 40 moves from the initial pushing position toward the middle position. In the process of pushing away material 40 by material pushing component 3213, on the one hand, two guide units 3212 can provide the guide effect for material 40, and on the other hand, when material 40 moved on load-bearing part 32111, because its left and right sides respectively with two guide units 3212 contact, material 40 can guarantee the degree of accuracy of its left and right direction's gesture under the effect of two guide units 3212, guarantee that material 40 can not produce the deviation in its left and right direction. In this way, the first pushing mechanism 321 is used to push the material 40, so that the accuracy of the posture of the material 40 can be ensured, and the material 40 is prevented from being processed into a defective product due to deviation of the material 40 in the left-right direction during sewing, and the reliability is high.

After the material 40 moves to the middle position, the first lifting driving element 322311 may drive the front limiting element 322312 to descend first, so that the front limiting element 322312 limits the front side of the material 40 first, then the second lifting driving element 322321 drives the rear limiting element 322322 to descend, so that the rear limiting element 322322 limits the rear side of the material 40, at this time, the material 40 is limited between the front limiting element 322312 and the rear limiting element 322322, and then the third lifting driving element 322331 drives the middle pressing element 321317 to descend again, so that the middle pressing element 321317 compresses the material 40. The second push actuator 3222 is then able to move the material 40 from the intermediate position to the sewing position when actuated. The second pushing mechanism 322 can limit the front and rear sides of the material 40 by using the front limiting piece 322312 and the rear limiting piece 322322, so as to ensure the accuracy of the posture of the material 40 in the front and rear directions, avoid the material 40 from being processed into defective products due to the deviation of the material 40 in the front and rear directions during sewing, and have high reliability.

As shown in fig. 11, in the sewing apparatus of the present application, since the material 40 has an arc-shaped structure, the direction in which the material is pushed from the pushing start position to the sewing position is the direction from the front of the head 33 to the rear of the head 33.
