Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Please refer to fig. 1 to 6.

The embodiment provides an automatic feeder, which comprises a material pushing device 13, a material clamping device 100, a rotary material supporting device 200, a cover plate device 300 and an end cutting detection device 400.

The material pushing device 13 comprises a trough 12 for placing the material 10 and feed rods for pushing and pulling the material 10, the feed rods comprise a first feed rod 15 and a second feed rod 16, and the material 10 can slide in the trough 10.

The feed rod splitting of prior art is first feed rod 15 and second feed rod 16, can shorten autoloader's whole length.

The rotary material supporting device 200 and the material clamping device 100 are arranged at the interrupted zone of the trough 10, and the material clamping device 100 is used for clamping, fixing and releasing the material 10.

Specifically, in order not to affect the processing, it is necessary to fix the trailing end of the material 10 while processing the material 10. Thus, the front end of the second feed bar 16 is provided with a jaw for gripping the tail end of the material 10. When the materials are fed to the material clamping device 100, the materials 10 are clamped and fixed through the material clamping device 100, then the first feeding rod 15 drives the second feeding rod 16 to move forwards to be abutted against the tail end of the materials 10, and under the action of the extrusion force, the tail end of the materials 10 is clamped into the clamping jaw at the front end of the second feeding rod 16. Optionally, the jaws are resilient jaws.

Further, when retrieving the tails, pull out the tails through pressing from both sides material device 100 to can detect whether press from both sides tightly to have the tails and whether release and loosen the tails, ensure that the tails has been brought back, avoid the tails to lose in the midway, also ensure that the tails falls to retrieve successfully.

The rotary supporting device 200 has a normal state and a reversed state. Because the feeding and the tailing recovery are needed, the rotary material supporting device 200 is in a normal state during feeding, namely, is in parallel butt joint with the trough, so that the material 10 is prevented from arching, and the material 10 can smoothly pass through the interrupted belt.

When the tailings are recovered, the second feeding rod 16 brings the tailings back, the tailings are clamped through the material clamping device 100, the tailings are pulled out from the second feeding rod 16, and the tailings are transferred to the material clamping device 100. At this time, the rotary material supporting device 200 should be in a turning state, staggered from the trough 12, and avoid the space for the tailing to fall and be recovered, that is, the material clamping device 100 loosens the tailing, so that the tailing falls and is recovered from the interrupted belt.

The cut end detection device 400 is disposed at the discharge end 14 of the trough 12 and is used for detecting whether the trough 12 has material therein. The cut end detecting device 400 is provided with a detecting piece 34, and the detecting piece 34 is jacked up when the material 10 comes out from the discharging end 14, so that whether the material exists or not is detected through the position change of the detecting piece 34. As the feeding continues, the material 10 continues to be fed out, and the detection piece 34 is controlled to turn over and leave the material 10, so that the material 10 is prevented from being pressed down to affect the processing.

The cover device 300 is disposed above the trough 12 to form a receiving space with the trough 12 to prevent the material 10 from arching.

Specifically, the cover device 300 is provided with a first cover 71 and a second cover 75. When the second feeding rod 16 pushes materials, if the second feeding rod 16 does not reach the vicinity of the first cover plate 71 and the second cover plate 75, the first cover plate 71 and the second cover plate 75 are closed, so that the materials 10 can be prevented from arching; when the position near the first cover plate 71 is reached, the first cover plate 71 is opened, and the second feeding rod 16 can pass through the first cover plate; when the vicinity of the second cover plate 75 is reached, the second cover plate 75 is opened, facilitating the passage of the second feed bar 16.

Specifically, the feeding method of the automatic feeding machine comprises the following steps:

step S0, in the initial state, the first feeding bar 15 is located at the initial position; the second feeding rod 16 is lifted, so that the blanking device 11 is convenient to blank; the rotary material supporting device 200 is in a normal state, so that the material 10 can pass through the interrupted belt conveniently; the first cover plate 71 and the second cover plate 75 of the cover plate device 300 are in an open state, so that the blanking device 11 can conveniently carry out blanking; the cut end detection device 400 is in a detection state, namely the detection sheet 34 thereof shields the outlet of the discharge end 14;

step S1, the blanking device 11 blanks the material 10 into the trough 12; the specific structure of the blanking device 11 is the prior art, and is not described herein again;

step S2, moving the driving plate 23 forward, i.e. moving to the left in fig. 1, so that the first cover plate 71 and the second cover plate 75 of the cover plate device 300 are closed; after the material 10 is blanked, the first cover plate 71 and the second cover plate 75 are closed at the first time, so that the material 10 can be prevented from arching, particularly when the material 10 is thin and long in size, the problem that the material 10 arches easily always occurs in the prior art, and the problem can be solved by the arrangement;

step S3, the first feeding rod 15 pushes the material 10 to move a first preset distance in the trough 12, where the first preset distance may be set according to actual conditions, so as to prepare for lowering the second feeding rod 16 after pushing the first preset distance, specifically, reserve a placement position for the second feeding rod 16 in the trough 12;

step S4, returning the first feed lever 15 to the initial position;

step S5, the driving plate 23 continues to move forward, so that the second feeding rod 16 is lowered and is fixedly connected with the first feeding rod 15 in a limiting manner, and therefore, when the pushing device 13 pushes the first feeding rod 15, the second feeding rod 16 can be driven to move at the same time;

step S6, the clamping device 100 clamps the material 10;

step S7, the first feeding rod 15 drives the second feeding rod 16 to move forwards, so that the tail end of the material 10 is clamped by a front end clamping jaw of the second feeding rod 16 under the action of extrusion force, and the inserting process is completed;

step S8, the material clamping device 100 loosens the material 10;

step S9, if the length of the material 10 is the first length value, the end-cutting detecting device 400 detects whether there is a material; if the length of the material 10 is the second length value, the first feeding rod 15 drives the second feeding rod 16 to move forward for a second preset distance, and then the end cutting detection device 40 detects whether the material exists; it should be noted that the initial lengths of the materials 10 may be different, that is, the automatic feeding machine may push the materials 10 with different lengths and sizes; the lengths of the first feeding rod 15 and the second feeding rod 16 are fixed, so that when the material is a long material, namely a first length value, the material 10 can jack up the detection sheet 34 for end cutting detection only after the material is pushed for a distance of a first preset value; when the material is a short material, that is, the material is a second length value, the material 10 can reach the short material after the short material needs to be pushed by a distance of a second preset value, so as to jack up the detection sheet 34 for end cutting detection;

step S10, if the existence of the material is detected, the next step is carried out; otherwise, sending out a material shortage alarm; the cut end detection is performed at a better time, and the material 10 does not need to be detected before the cut end detection, so that the detection reliability is improved;

step S11, the driving plate 23 moves forward continuously, the detecting plate 34 of the end-cutting detecting device 400 lifts off the material 10, so as to prevent the detecting plate 34 from pressing down the material 10 continuously and prevent the processing of the material 10 from being affected;

step S12, according to the length of each section of processing, the first feeding rod 15 drives the second feeding rod 16 to move forwards step by step; i.e. feeding according to the processing step distance of the material 10; it should be understood that each time a double distance of the process segment may be pushed, the cutting of the material 10 may be accomplished at equally spaced segments, but may also be non-equally spaced segments; it should be noted that, in the specific implementation process, the machine tool is used as the main part, and the feeder is used as the auxiliary part, that is, how far the machine tool travels, the feeder pushes the corresponding distance;

step S13, when the second feeding rod 16 approaches the first cover plate 71 of the cover plate device 300, the driving sheet 23 continues to move forwards, and the first cover plate 71 is opened so that the second feeding rod 16 can pass through;

step S14, when the second feeding rod 16 approaches the second cover plate 75 of the cover plate device 300, the driving plate 23 continues to move forward, and the second cover plate 75 is opened; at this time, the rotary material supporting device 200 can be controlled to turn over through the driving sheet 23;

step S15, after the processing is finished, the second feeding rod 16 brings the tailings back to the material clamping device 100;

step S16, the material clamping device 100 clamps the tailings and detects whether the tailings exist;

step S17, if the tailing is detected, the next step is carried out; otherwise, sending out a tailing loss alarm; the arrangement can ensure that the tailing is brought back successfully, and the safety is ensured;

step S18, pulling the tailings out of the front end of the second feeding rod 16, and transferring the tailings onto the material clamping device 100 to finish the material pulling process;

step S19, the material clamping device 100 releases the tailings, the tailings fall and are recovered from the position where the rotating material supporting device 200 at the position of the interrupted belt is moved away, and meanwhile, whether the material clamping device 100 is released or not can be detected; if so, finishing the recovery of the tailings and carrying out the next step; otherwise, sending out a recovery failure alarm; the arrangement can ensure the successful recovery of the tailings and ensure the safety;

in step S20, the driving plate 23 returns to the initial position, i.e., moves backward, i.e., moves rightward in fig. 1, and the first feeding bar 15, the second feeding bar 16, the rotary stocker 200, the cover plate device 300, and the cut-end detecting device 400 return to the initial state.

Therefore, the automatic feeding machine and the method provided by the embodiment can respectively control the opening and closing timing of the cover plate device 300, the lifting timing of the second feeding rod 16, the opening and closing timing of the detection function of the cut end detection device 400 and the turning timing of the rotary material supporting device 200 through the driving sheet 23, and can ensure the safety, efficiency and accuracy of the processing process of the material 10.

Wherein, the blanking device 11 can be realized by adopting the prior art means.

As shown in fig. 2 and 3, in the pusher 13, a gear 21 is driven by a motor 19, a rack 22 is connected to the gear 21, and a driving piece 23 is connected to the rack 22.

It should be understood that the first slope 25 may be provided with a slope inclined to the left and a slope inclined to the right in order to achieve the elevation of the second feed bar 16. The same applies to the following slopes. Then, by setting the positions of the first slope 25 and the first roller 24, the timing of the elevation of the second feed bar 16 can be controlled.

The first feeding rod 15 is pushed and pulled by the push-pull driving assembly 20 to move back and forth in the trough 12.

When the second feeding rod 16 descends, the first feeding rod 15 can be fixedly connected through the limiting structure in a sleeved mode, and therefore when materials are pushed, the second feeding rod 16 and the first feeding rod 15 move synchronously.
