Detailed Description
Example one
As shown, a roller feeder includes: the bottom plate 103 is mounted on the base 101 through a first driving mechanism, and the first driving mechanism is used for driving the bottom plate 103 to enable the bottom plate 103 to incline. The base 101 is mounted on the processing apparatus, and the inclination of the base plate 103 is controlled by a driving mechanism, so that the workpiece can slide by gravity. Specifically, the first driving mechanism comprises a first air cylinder 102 installed on the left side of the upper end of the base 101, and the first air cylinder 102 is connected with a first piston rod hinged with the left side of the lower end of the bottom plate 103. The right side of the lower end of the bottom plate 103 is hinged with the right side of the lower end of the base 101 through a connecting seat 107. As soon as the piston rod is extended, the left side of the bottom plate 103 moves upwards, so that the height of the left side of the bottom plate 103 is higher than the right side of the bottom plate 103.
And a second side baffle plate 115 and a first side baffle plate 106 are fixedly arranged on the front side and the rear side of the bottom plate 103 through bolt connection respectively. A right baffle plate 111 is fixedly mounted on the right side of the bottom plate 103 by means of bolt connection. A slide plate 104 is fixedly mounted to the upper end of the base plate 103 by means of a bolt connection. A workpiece is placed on the left end of the slide plate 104 by a human or robot hand, and slides along the right end of the slide plate 104 under the action of gravity.
The limiting plate 105 is arranged at the upper end of the sliding plate 104 in a front-back adjustable mode, the distance between the limiting plate 105 and the second side baffle 115 can be adjusted by adjusting the installation position of the limiting plate 105, so that the distance is slightly larger than the length of the workpiece to be conveyed, the distance is 105% -110% of the length of the workpiece to be conveyed, and the workpiece can slide on the sliding plate 104 between the limiting plate 105 and the second side baffle 115.
And a telescopic upper baffle is arranged between the limit plate 105 and the second side baffle 115, and specifically, two ends of the telescopic upper baffle are respectively arranged on the limit plate 105 and the second side baffle 115 in a vertically sliding manner. The distance between the telescopic upper baffle and the upper end face of the sliding plate 104 can be adjusted, so that only one workpiece to be conveyed is allowed to slide along the sliding plate 104, two or more workpieces are placed to be overlapped up and down to pass through, and the workpieces are conveyed according to pieces. The telescopic upper baffle comprises a first upper baffle 201, a first accommodating groove 208 is formed in the first upper baffle 201, a second upper baffle 204 is installed in the first accommodating groove 208 in a sliding mode, and the second upper baffle 204 is provided with a sliding strip 206, so that the second upper baffle 204 can horizontally slide relative to the first upper baffle 201. The lower end faces of the first upper baffle plate 201 and the second upper baffle plate 204 are flush, so that the workpiece is prevented from sliding. The telescopic upper baffle is arranged in a two-end mode, so that the length of the telescopic upper baffle can be changed when the distance between the limiting plate 105 and the second side baffle 115 can be adjusted.
The first inclined plane 210 is arranged at the lower end of the left side of the first upper baffle plate 201, and the second inclined plane 211 is arranged at the lower end of the left side of the second upper baffle plate 204. Thereby facilitating entry of the workpiece into the space between the telescoping top stop and the slide plate 104.
And a second driving mechanism 113 is installed on the limit plate 105, and the telescopic upper baffle can be driven to move up and down through the second driving mechanism 113. Specifically, the second driving mechanism 113 is a linear sliding table, a sliding block 212 is installed on the linear sliding table, and one end of the sliding block 212 penetrates through the rectangular groove 112 formed in the limiting plate 105 and is fixedly connected with the first upper baffle 201. And a limiting slide block 205 is fixedly connected to the second upper baffle 204, and the limiting slide block 205 is installed in a vertical sliding groove formed in the second side baffle 115. Manual linear sliding tables can be selected for use, a hand wheel is shaken, the telescopic upper baffle can be controlled to move up and down, and therefore the distance between the telescopic upper baffle and the sliding plate 104 is adjusted. The distance is 105% -110% of the height of the workpieces to be conveyed, so that smooth sliding of the workpieces can be met, and blockage and incapability of conveying the workpieces according to the workpiece due to stacking of a plurality of workpieces can be avoided.
The left side of the telescopic upper baffle is easy to cause workpiece accumulation, so that a first dredging mechanism is installed on the first upper baffle 201, a second dredging mechanism is installed on the second upper baffle 204, and the first dredging mechanism and the second dredging mechanism are used for dredging workpieces blocked on the left sides of the first upper baffle 201 and the second upper baffle 204. Specifically, the first dredging mechanism comprises a second air cylinder 202 fixedly connected to the first upper baffle plate 201, and the second air cylinder 202 is connected with a first vertical push rod 207 through a second piston rod. The second dredging mechanism comprises a third air cylinder 203 fixedly connected to a second upper baffle 204, and the third air cylinder 203 is connected with a second vertical push rod 209 through a third piston rod. When workpieces are stacked, the first vertical push rod 207 can be driven to move back and forth through the second air cylinder 202, and the second vertical push rod 209 can be driven to move back and forth through the third air cylinder 203, so that the stacked workpieces are pushed out through the first vertical push rod 207 and the second vertical push rod 209.
In order to avoid the interference of the vertical push rod III 209 with the normal telescopic motion of the upper baffle plate II 204, a second accommodating groove 213 is formed in the left side of the upper baffle plate II 204, and when the piston rod III is in a contraction state, the vertical push rod II 209 is located in the second accommodating groove 213. Therefore, when the second upper baffle 204 is not extended, the second vertical push rod 209 is positioned in the second accommodating groove 213; when the second upper baffle 204 needs to retract into the first accommodating groove 208, the second vertical pushing rod 209 can be locked into the second accommodating groove 213.
One end of the bottom plate 103 close to the right baffle 111 is provided with a feeding mechanism, and workpieces can be conveyed in parts through the feeding mechanism. Specifically, the feeding mechanism includes a supporting plate 110 fixedly connected to one end of the front side of the bottom plate 103 close to the right baffle 111, and a bearing is mounted on the supporting plate 110. A transmission shaft 109 is arranged in the bearing, and the transmission shaft 109 is connected with a stepping motor. The transmission shaft 109 is fixedly connected with a roller 301, and a plurality of bins 303 are uniformly distributed on the outer circumferential surface of the roller 301 along the circumferential direction.

And a discharge hole 108 is formed at one end of the bottom plate 103 close to the right baffle 111. When the bin 303 faces the discharge port 108, the workpiece in the bin 303 falls into the processing equipment from the discharge port 108.
The feeding mechanism further comprises a transmission mechanism arranged in the roller 301, a limiting snap ring 305 and an arc-shaped sliding block 302 which are arranged on the bin 303. Therefore, the volume of the bin 303 can be adjusted by driving the limit snap ring 305 and the arc-shaped sliding block 302 through a transmission mechanism. The residual space of the bin 303 between the limiting snap ring 305 and the supporting plate 110 only accommodates one workpiece to be stored, so that the bin 303 can store workpieces with different sizes, the workpiece falling into the bin 303 cannot be easily displaced, and the dislocation in the processing equipment is avoided.
The transmission mechanism comprises a screw 311 which is rotatably arranged in the roller 301, and a screw slider 312 is arranged on the screw 311. One end of the screw 311 is fixedly connected with a rotating shaft 313, and a driving gear 314 is installed on the rotating shaft 313. The drive gear 314 is coupled to at least two, preferably four, pairs of arcuate sliders 302 via a gear set 316. The arcuate slider 302 is provided with a rack that engages a gear set 316. When the rotating shaft 313 rotates, the driving gear 314 rotates, and the gear set 316 drives the pair of arc-shaped sliders 302 to move toward or away from each other. A pair of arc-shaped sliding blocks 302 are respectively and slidably arranged at two circumferential sides of the storage bin 303. Specifically, the arc-shaped sliding block 302 is slidably installed in the roller 301, and one end of the arc-shaped sliding block 302 penetrates through a through hole formed in the bin wall of the bin 303 and extends into the bin 303. When the pair of arc-shaped sliding blocks 302 move towards or away from each other, the remaining space of the bin 303 changes correspondingly. The outer circumference of the roller 301 is sleeved with the limiting snap ring 305, and the limiting snap ring 305 is fixedly connected with a connecting rod 317. The connecting rod 317 penetrates through the rectangular through hole 304 formed in the roller 301 and is fixedly connected with the screw rod sliding block 312. The screw 311 rotates, and the screw slider 312 drives the limiting snap ring 305 to move linearly along the axial direction. Rubber stop pads are also mounted on the rectangular through holes 304 to prevent the workpiece from being clamped.
The inner circumferential surface of the limiting snap ring 305 is provided with an installation block 306 corresponding to the bin 303, telescopic blocks 307 are respectively slidably installed on two circumferential sides of the installation block 306, and a spring 318 is connected between the telescopic blocks 307 and the installation block 306. The mounting block 306 is located in the bin 303 and located between the pair of arc-shaped sliding blocks 302, the telescopic blocks 307 on two sides are respectively clung to the arc-shaped sliding blocks 302 on the same side, and when the arc-shaped sliding blocks 302 move, the telescopic blocks 307 are clung to the arc-shaped sliding blocks 302 all the time under the elastic force of the spring 318.
When the pair of arc-shaped sliding blocks 302 move towards or away from each other, the limiting snap ring 305 also moves adaptively, so that the two adjust the residual space of the bin 303 between the limiting snap ring 305 and the supporting plate 110 together.
The screw 311 is connected with a control mechanism, and the screw 311 can be driven or prevented from rotating by the control mechanism. The control mechanism comprises a rotating block 309 fixedly connected with one end of the screw 311, which is far away from the rotating shaft 313, an inserting rod 315 is arranged on the rotating block 309 in a sliding mode along the radial direction, and the inserting rod 315 is fixedly connected with a shifting block 310. The roller 301 is provided with slots 308 along the circumferential direction of the rotating block 309. The rotatable turning block 309 rotates the lead screw 311.
