The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

With reference to fig. 1 and 2, the material taking and feeding device 100 of the present invention is mainly used for inserting, taking and transporting a workpiece 200 having a processing opening 2001, such as a U-shaped buckle. Of course, it can be understood that the workpiece 200 that the material taking and feeding device 100 can transfer and transport includes, but is not limited to, the U-shaped buckle, and the material taking and feeding device 100 can also transfer and transport other workpieces 200.

Referring to fig. 1 to 4, a material taking and feeding device 100 according to a preferred embodiment of the present invention includes a driving mechanism 10 and a material taking and feeding mechanism 20.

Preferably, referring to fig. 1 and 3, the driving mechanism 10 includes a driving shaft 11, a driving member 12 and an intermittent drive assembly 13.

Wherein, the driving member 12, such as a driving motor, is connected to the driving shaft 11 to drive the driving shaft 11 to rotate continuously. The intermittent transmission assembly 13 is connected with the driving rotating shaft 11 to intermittently output the rotating motion of the driving rotating shaft 11.

In other words, when the driving member 12 drives the driving shaft 11 to rotate continuously, the continuous rotation of the driving shaft 11 is converted into an intermittent rotation by the intermittent transmission assembly 13, i.e. an intermittent rotation that rotates for a period of time and does not rotate for a period of time is output.

Preferably, with reference to fig. 1 and 4, the material taking and feeding mechanism 20 includes a storage bin 21, a conveying track 22, a material taking rotating shaft 23 and a rotary sifter 24.

Wherein, a storage cavity 2101 is formed in the storage box 21 for storing the workpieces 200, and the storage box 21 is formed with a top opening 2102 and a side opening 2103 which are communicated with the storage cavity 2101.

The conveying track 22 is disposed at one side of the storage box 21, and the input end 221 of the conveying track 22 is aligned with and close to the side opening 2103.

Get material pivot 23 level setting and be in top opening 2102 top, just get material pivot 23 with intermittent type drive subassembly 13 links to each other. The rotary sifting element 24 is disposed on the material taking rotating shaft 23 and has at least one sifting arm 241, the sifting arm 241 extends along the radial direction of the material taking rotating shaft 23, and the outer diameter of the sifting arm 241 is matched with the inner diameter of the processing opening 2001 of the workpiece 200, for example, the width of the sifting arm 241 is equal to the inner diameter of the processing opening 2001 of the workpiece 200, so that the sifting arm 241 is suitable for being inserted into the processing opening 2001 of the workpiece 200.

Thus, when the intermittent drive assembly 13 outputs continuous rotational motion, the intermittent drive assembly 13 drives the material taking rotating shaft 23 and the sieving arm 241 to rotate around the axis of the material taking rotating shaft 23, so that the sieving arm 241 extends into the material storage cavity 2101 to insert and take the workpiece 200. When the intermittent drive assembly 13 does not output continuous rotation motion, the sieving arm 241 stops rotating, the sieving arm 241 extends obliquely downwards and abuts against the input end 221 through the side opening 2103, and therefore the workpieces 200 on the sieving arm 241 slide into the conveying track 22 in order through the side opening 2103 under the action of gravity and are conveyed away from the conveying track 22 in order.

Therefore, get material feeding unit 100 and realized promptly right work piece 200 insert fast, high-efficiently and get and carry, degree of automation is high, work piece 200 is got and is sent efficiently, and is with low costs.

In addition, the screening arm 241 can also play a certain screening role on the workpiece 200 because the outer diameter of the screening arm 241 is matched with the inner diameter of the processing opening 2001 of the workpiece 200. For example, if other workpieces 200 are mixed in the accumulated workpieces 200, or the inner diameter of the processing opening 2001 of the workpiece 200 does not meet the standard, for example, the inner diameter of the processing opening 2001 is too small, the screening arm 241 will not be inserted into the processing opening 2001 of the workpiece 200, and the material will not be taken from the workpiece 200 with the unqualified processing quality.

Preferably, in conjunction with fig. 3 and 5, the intermittent drive assembly 13 includes a driving sheave 131 and a driven sheave 132. Wherein, the driving sheave 131 is arranged on the driving rotating shaft 11, and at least one sliding column 1311 is formed on the surface of the driving sheave 131. The driven sheave 132 forms at least one sliding passage 13201 adapted to the spool 1311 to slide, the sliding passage 13201 extends radially along the driven sheave 132, and a port of the sliding passage 13201 is formed in a peripheral wall of the driven sheave 132 so that the driven sheave 132 is intermittently rotated by the spool 1311 intermittently sliding in the sliding passage 13201 while the driving shaft 11 is continuously rotated.

That is, when the driving member 12 drives the driving shaft 11 to rotate continuously, the driving shaft 11 rotates continuously to drive the driving sheave 131 to rotate continuously, and the driving sheave 131 rotates continuously to cause the sliding column 1311 on the surface of the driving sheave 131 to slide into and out of the slideway 13201 intermittently, so that the sliding column 1311 on the surface of the driving sheave 131 slides in the slideway 13201 intermittently. As the spool 1311 slides within the ramp 13201, the driven sheave 132 rotates with the driving sheave 131. And when the spool 1311 does not slide in the slide 13201, the driven sheave 132 stops rotating. In this way, when the driving member 12 drives the driving shaft 11 to rotate continuously, the driven sheave 132 is driven to rotate intermittently, so as to achieve intermittent output of continuous rotational motion, that is, the continuous rotational motion of the driving shaft 11 is converted into intermittent rotational motion.

Specifically, for example, in conjunction with fig. 5, after the sliding column 1311 slides out of the slideway 13201 along the rotating direction S, the driving sheave 131 can not rotate to drive the driven sheave 132, and thus the driven sheave 132 stops rotating for a period of time. After the sliding column 1311 rotates and slides into the slideway 13201 again, the driving sheave 131 rotates to drive the driven sheave 132 to rotate again, and the driving sheave 132 rotates in a reciprocating manner, so that the driven sheave 132 rotates intermittently.

Specifically, there are two sliding columns 1311, two sliding columns 1311 are uniformly spaced along the circumferential direction of the driving sheave 131, there are four sliding ways 13201, and four sliding ways 13201 are uniformly spaced along the circumferential direction of the driven sheave 132.

Preferably, referring to fig. 1 and 3 to 4, the conveying track 22 is disposed at the rear side of the storage box 21, and the intermittent drive assembly 13 further includes a first drive rotating shaft 133, a second drive rotating shaft 134 and a drive gear set 135.

Wherein the first driving rotation shaft 133 is provided with the driven sheave 132. The second transmission rotating shaft 134 and the driving rotating shaft 11 are arranged side by side, and the second transmission rotating shaft 134 is connected with the material taking rotating shaft 23. Referring to fig. 3, the drive gear set 135 includes a first gear 1351 and a second gear 1352. The first gear 1351 is disposed on the first transmission rotation shaft 133. The second gear 1352 is arranged on the second transmission rotating shaft 134, and the second gear 1352 is meshed with the first gear 1351 and is larger in diameter than the first gear 1351. Thus, when the driven sheave 132 rotates counterclockwise, the first transmission shaft 133 and the first gear 1351 rotate counterclockwise, so as to drive the second gear 1352 and the second transmission shaft 134 to rotate along with the pointer, and further drive the material taking shaft 23 and the sieving arm 241 to rotate along with the pointer. When the driven sheave 132 stops rotating, the sifting arm 241 also stops rotating. Therefore, the arrangement is realized that the driven sheave 132 intermittently rotates counterclockwise to drive the sieving arm 241 to intermittently rotate along the indicating needle, so that the sieving arm 241 extends out of the side opening 2103 to abut against the conveying track 22 at the rear side of the storage box 21.

In addition, since the first gear 1351 has a smaller diameter than the second gear 1352, a reduction and labor saving effect can be achieved. Therefore, the sifting arm 241 can smoothly insert and extract the workpiece 200 with a small driving force of the driving shaft 11.

According to a preferred embodiment of the present invention, referring to fig. 3, the driving mechanism 10 further includes a driving frame 14, and the driving shaft 11, the first driving shaft 133 and the second driving shaft 134 are rotatably disposed on the driving frame 14.

Preferably, in conjunction with FIG. 4, the storage chamber 2101 is tapered in diameter in a direction from top to bottom. Thus, the work pieces 200 are conveniently fed into the storage chamber 2101 for storage through the top opening 2102, and the work pieces 200 are stacked in the storage box 21 having a tapered shape, so that the work pieces 200 can be easily obliquely inserted and taken by the sifting arm 241 when rotating.

Preferably, with reference to fig. 4 and 6, the plurality of sifting arms 241 are provided, the plurality of sifting arms 241 are arranged at intervals along the circumferential direction of the material taking rotating shaft 23, and each sifting arm 241 has an arc concave surface 24101 which is concave towards the adjacent sifting arm 241. Thus, the inserted work 200 is not easily dropped from the sifting arm 241 in the process of rotating the material taking rotary shaft 23.

Specifically, the number of the sieving arms 241 is four, and the sieving arms 241 are arranged along the circumferential direction of the material taking rotating shaft 23 at even intervals.

According to the utility model discloses a preferred embodiment, combine fig. 4, get feeding mechanism 20 and include one get pay-off frame 25 and a manual rotary disk 26, it rotationally sets up to get material pivot 23 get in the pay-off frame 25, manual rotary disk 26 sets up get the pay-off frame 25 outside, just manual rotary disk 26 with it links to each other to get material pivot 23. In this way, the manual rotating disc 26 can be manually controlled to intermittently rotate, so that the sieving arm 241 can intermittently rotate, and can replace the driving mechanism 10 to perform a driving function in case of an accident.

Further, referring to fig. 4, the manual rotation plate 26 includes a rotation plate 261 and a manual rotation handle 262. The rotating disc body 261 is connected with the material taking rotating shaft 23, and the manual rotating handle 262 is arranged on one side of the rotating disc body 261, which is far away from the material taking and feeding rack 25. Thereby, the operator is facilitated to drive the manual rotation disc 26 to rotate.

Preferably, at least a part of the outer diameter of the conveying track 22 is matched with the inner diameter of the processing opening 2001 of the workpiece 200, for example, the width of the part is equal to the inner diameter of the processing opening 2001 of the workpiece 200, the workpiece 200 is slidably sleeved on the part, the conveying track 22 extends from top to bottom along the direction perpendicular to the material taking rotating shaft 23, and the height of the input end 221 of the conveying track 22 is higher than that of the output end 222 of the conveying track 22. Thus, after the workpiece 200 slides into the conveying track 22, the workpiece 200 can slide from the input end 221 to the output end 222 with the downward posture of the processing port 2001 maintained under the action of gravity, and the workpiece 200 can be automatically and orderly conveyed.

Further, the conveying track 22 extends in an arc shape, and a portion of the conveying track 22 close to the storage box 21 is recessed downward, and a portion far away from the storage box 21 is recessed upward.
