That is, the gate is also a part constituting the discharge port K as long as the movement of the gate allows the long bar stock to fall from the first discharge port K1 and the second discharge port K2.

The first barrier c 'is vertically arranged, a discharge space for a long rod to fall is formed between the lower end of the first barrier c' and the oblique edge of the first frame a ', and the first gate e' is horizontally arranged above the discharge space, wherein when the first gate e 'moves horizontally to the feeding end of the first frame a', the first discharge opening K1 is opened.

That is, under the driving of the first driver g 'and the second driver h' which move synchronously, the first discharge port K1 and the second discharge port K2 move synchronously, so that the discharge ports are opened, and the width of the discharge ports is equal to the outer diameter of the long rod, at this time, the long rod is discharged one by one from the discharge ports and forms the first pass discharge unit.

In this application, when the uninstallation mouth was opened, if take place the unloading when not smooth, can also adjust the telescopic link small amplitude telescopic motion that makes a round trip for first gate e 'and second gate f' further open and closed motion, the long rod state of adjustment long rod bearing area makes the smooth unloading of long rod, promptly, reduces the phenomenon of putty and takes place.

The baffle s211 further comprises a third baffle i 'and a fourth baffle j' which are arranged on the truss and are respectively arranged in parallel with the inner end surfaces of the first frame body a 'and the second frame body b', wherein a third discharge opening K3 is formed between the third baffle i 'and the inner end surface of the first frame body a'; a fourth discharge opening K4 is formed between the fourth baffle j 'and the inner end surface of the second frame body b', the third discharge opening K3 and the fourth discharge opening K4 are aligned to form a discharge passage X, and the width of the discharge passage X is 1.2 times of the outer diameter of the long rod. That is, the long rod material in this embodiment is unloaded from the discharge port K to the discharge channel X, and then discharged from the bottom of the discharge channel X, and at this time, a second discharge unit is formed. The device has the advantages that on one hand, the accuracy of the falling position of the bar stock is high, and the bar stock can fall into the feeding groove below the bar stock accurately; on the other hand, when the material rod is clamped (mainly at the unloading port), the position and the state of the material rod are adjusted by the movement of the first gate and the second gate at the unloading port, so that the long rod material is smoothly unloaded, and meanwhile, only one material loading groove is unloaded to the lower part from the unloading channel at each time under the assistance of the unloading channel.

The long bar feeding unit s3 comprises an annular conveyor belt s30 arranged on the other side of the truss s20 and horizontally arranged on the vehicle frame s10, and a driving assembly s31 for driving the annular conveyor belt s30 to rotate, wherein the feeding end (right end) of the annular conveyor belt s30 is positioned below the unloading channel X, and the discharging end (left end) is arranged from the opposite side of the vehicle frame s10 corresponding to the supporting frame s 21.

In this example, a plurality of feeding grooves s30a extending along the width direction of the annular conveyor belt are uniformly distributed on the circumferential surface of the annular conveyor belt s30, each feeding groove s30a is matched with a long rod to be fed, when a specified machine tool needs to be fed, the discharging end part of the annular conveyor belt s30 is inserted into the machine tool to feed, the discharging opening is opened, the long rod falls into the corresponding feeding groove one by one through the discharging opening and the discharging channel, and the long rod is fed into the feeding center of the machine tool one by one from the discharging end part under the transmission of the annular conveyor belt.

Meanwhile, the inner and outer circumferential surfaces of the endless conveyor belt s30 are provided with a feeding groove s30a and a driving groove s30b, which are recessed inward from the surface, respectively, wherein the feeding groove s30a and the driving groove s30b have the same shape and structure. Therefore, as long as the annular belt is adopted, the front surface and the back surface are universal, and the practical use and installation are very convenient.

In order to simplify the construction and to reduce the weight, the support is constructed in such a way that the frame bars are connected to one another.

In this example, there are two endless conveyors s30, and two endless conveyors s30 are arranged side by side and aligned along the length of truss s20 between the first frame a 'and the second frame b', and the feeding end of endless conveyor s30 extends below the inclined surface; the discharge end portion protrudes outside the vehicle frame s 10.

The two endless conveyors s30 move synchronously, the feeding troughs s30a on the two endless conveyors s30 are arranged in one-to-one correspondence, and each long bar B falling from the unloading channel X falls into the two feeding troughs s30a corresponding to the long bar B, so that the long bar B is supported and transshipped and positioned.

Specifically, the driving assembly s31 includes a driving wheel s310 and a driven wheel s311 which are in matched butt joint with the driving grooves s30b of each endless transmission belt s30, a synchronizing shaft s312 for synchronously connecting two adjacent driving wheels s310, and a driving motor s313 and a transmission member s314 for driving the synchronizing shaft s312 to rotate around the axes thereof.

The transmission s314 may take the form of a belt-pulley or gear-mesh transmission, which will not be described in detail herein.

Meanwhile, it is also a conventional means in the art to adjust the distance between the driving pulley s310 and the driven pulley s311 so as to tension the endless belt in consideration of the different load-bearing capacities of the endless transmission belt s30, and it will not be described in detail herein.

In this case, the number of the channels s30a of the endless conveyor s30 on the upper surface is greater than the number of feeds required per processing unit, and the opening width of the discharge opening is equal to the outer diameter of the long bar to be fed. Thus, it is generally the case that a batch of material falls substantially onto the loading chute of the corresponding horizontal segment of the endless conveyor.

Meanwhile, it should be noted that, in this example, the height of the unloading port is matched with the moving distance of the endless conveyor in unit time, that is, after the endless conveyor moves for every pitch groove distance, a long bar falls from the unloading port, so that a batch of long bars falls into each feeding groove passing below the unloading port one by one.

In this example, in order to realize quantitative feeding (without manually counting) for each machine tool, the following two methods can be adopted:

1) the automatic feeding device also comprises a weighing mechanism (not shown in the figure, but not difficult to think) which is arranged on the transfer skip car and used for weighing long bars loaded in each batch, wherein the weighing mechanism is communicated with the driving assembly, when in feeding, the weight reduced each time is the weight of one long bar, and when the reduced weight is equal to the total weight of the required feeding number, the driving assembly is switched to move in a reverse direction to return the long bars close to the output end part to the horizontal section of the endless conveyor belt. The purpose that sets up like this can realize the feed of the long bar of required radical of a batch, and unnecessary long bar returns endless conveyor's horizontal segment again simultaneously, makes things convenient for unnecessary long bar to remove like this, prevents that long bar from losing from endless conveyor discharge end portion.

Meanwhile, the applicant needs to supplement that once interruption occurs in the weighing process, which indicates that the unloading port may be blocked, one solution is to alarm; the other solution is that the telescopic rod moves back and forth in a small amplitude, so that the problem of blockage at the unloading port is automatically solved.

) The automatic feeding device also comprises a counting mechanism communicated with the driving component, wherein the counting mechanism is used for counting the number of long bars transmitted out of the annular conveyor belt, when the number of the fed bars is equal to the number of the required bars, the driving component is switched to move in a reverse direction, and the long bars close to the output end part are returned to the horizontal section of the annular conveyor belt. Thus, redundant long bars can be conveniently moved, and the long bars are prevented from being lost from the discharge end part of the annular conveyor belt.

In 2), as to how to realize the statistics of the number of the long bars transmitted from the endless conveyor, a photoelectric sensor commonly used in the field can be adopted, when the photoelectric sensor senses that one long bar is discharged from the endless conveyor, the number of the long bars is counted, and when the accumulated number of the counts is equal to the number of the long bars needing to be fed, the driving assembly is switched to move in the reverse direction, and the long bars close to the output end are sent back to the horizontal section of the endless conveyor. Or according to the time, the reason is simple, because the moving speed of the endless conveyor belt is stable, a sensor is arranged at the output end, once a long bar material is discharged, the timing is started, and after the set time, the discharging is stopped and the reverse rotation is carried out, so that the feeding can be quantitatively finished.

Similarly, once interruption occurs in the counting process, the unloading port is probably blocked, and one solution is alarm; the other solution is that the telescopic rod moves back and forth in a small amplitude, so that the problem of blockage at the unloading port is automatically solved.

In the embodiment, the two means are combined, so that mutual authentication is performed between the two means, and feeding is completed more accurately.

Meanwhile, baffle plate assemblies s4 extending in the long rod conveying direction are provided at both ends of the truss s20, and the baffle plate assemblies s4 at both ends are symmetrically provided.

Specifically, the baffle assembly s4 includes a sealing plate s40 disposed perpendicular to the truss s20, and guide flanges s41 bent inward from both ends of the sealing plate s 40. In this case, the baffle assembly s4 is provided to prevent sudden stop during the transfer of long rods, which may result in unexpected transportation accident due to the impact of the long rods from the feeding chute. Meanwhile, under the action of the guide folding edge s41, the long rod materials which are staggered conveniently can be smoothly ejected into the long rod material bearing area.

In summary, the implementation process of this embodiment is as follows:

a) moving the transfer trolley to the side where the unloading surface of the long bar material distribution device is located, correspondingly inserting the first frame body and the second frame body below the unloading surface, butting the unloading surface with the inclined surface, and freely rolling the long bars into a long bar material bearing area with a closed unloading opening when the long bar material distribution device unloads the materials in batches;

b) after material taking is finished, moving the material transferring trolley to the machine tool, butting the discharge end part of the annular conveyor belt with the feeding material of the machine tool, opening an unloading opening and operating the annular conveyor belt, wherein the long bars roll from the unloading opening one by one into a feeding groove passing through the lower part of the unloading opening in sequence, and then the long bars are conveyed to the machine tool one by one under the operation of the annular conveyor belt;

c) through the double combination of weighing and counting, after the feeding number of the annular conveyor belt is determined, the annular conveyor belt reversely runs, and redundant long bars are transferred to a feeding port of a next machine tool or directly fed back to a long bar stacking area, so that the automatic feeding process of the long bars is completed.

Therefore, this application adopts batch material loading, that does not need the manual work to count, the long bar is removed to the manual work, then quantitatively send long bar to machining center through the delivery vehicle, and under the motion of the last silo of endless conveyor, each long bar that unloads from the uninstallation mouth falls into the last silo through unloading the below in proper order, and carry out the material loading to the pan feeding tip of lathe, simultaneously, once quantity or weight reach standard after, stop the feed and reverse rotation endless conveyor, move remaining long bar to the horizontal segment of endless conveyor's top, then transfer remaining long bar to the lathe of other required materials or directly transport back and roll to the pile district, so, through batching and continuous batch material supply after, can increase substantially the material loading efficiency of long bar, and more laborsaving, difficult mistake.

The present invention has been described in detail in order to enable those skilled in the art to understand the invention and to practice it, and it is not intended to limit the scope of the invention, and all equivalent changes and modifications made according to the spirit of the present invention should be covered by the present invention.
