Specifically, the first baffle c ' and the second baffle d ' are respectively positioned above the oblique sides of the first frame body a ' and the second frame body b ', and a first discharge opening K1 is formed between the first baffle c ', the first frame body a ' and the first gate e '; the second baffle d ', the second frame b ', and the second gate f ' form a second discharge opening K2; the first discharging opening K1 and the second discharging opening K2 are symmetrically arranged and form a discharging opening K. That is, the gate also forms part of the discharge opening K, so long as the movement of the gate allows the long rod to fall from the first discharge opening K1 and the second discharge opening K2.

The first baffle c 'is vertically arranged, a discharging space for a long rod to fall is formed between the lower end part of the first baffle c' and the inclined edge of the first frame body a ', the first gate e' is positioned above the side of the discharging space and is horizontally arranged, and the first discharging opening K1 is opened after the first gate e 'horizontally moves towards the feeding end part of the first frame body a'.

The first gate e 'comprises a first gate seat e1 positioned on the truss s20, a first sliding seat e2 horizontally arranged on the first gate seat e1 along the direction perpendicular to the length direction of the long bar material B, and a first supporting round rod e3 fixedly arranged on the first sliding seat e2 and extending along the length direction of the first sliding seat e2, wherein the cross section of the first supporting rod e3 is circular, the upper part of the circular shape upwards protrudes out of the first sliding seat e2 and forms a part of the first discharging opening K1, the contact area with the long bar material B is small, the opening and closing operation of the discharging opening K is facilitated, the first driver g' is used for pushing the first sliding seat e2 to move on the first gate seat e1, the long bar material B is erected on the first supporting rod e3 when the first discharging opening K1 is closed (shown in combination with fig. 9), and the long bar material B rolls out from the first discharging opening K1 when the size of the first discharging opening K1 is equal to the outer diameter of the long bar material B (shown in combination with fig. 10).

The symmetry principle shows that the second baffle d 'is also vertically arranged, and a discharging space for a long rod to fall is formed between the lower end of the second baffle d' and the inclined edge of the second frame b ', and the second gate f' is positioned above the side of the discharging space and horizontally arranged, wherein when the second gate f 'horizontally moves towards the feeding end of the second frame b', the second discharging opening K2 is opened.

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

In the application, when the unloading port is opened, if the blanking is not smooth, the telescopic rod can be regulated to perform small-amplitude back and forth telescopic movement, so that the first gate e 'and the second gate f' perform further opening and closing movement, the state of the long rod in the long rod bearing area is regulated, and the long rod is smoothly blanked, namely, the phenomenon of blocking is reduced.

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

The bar stock feeding unit s3 comprises an annular conveyor belt s30 arranged on the other side of the truss s20 and horizontally arranged on the 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 arranged below the unloading channel X, and the discharging end (left end) is arranged at the opposite side of the frame s10 corresponding to the support frame s 21.

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

Meanwhile, an upper trough s30a and a driving trough s30b which are recessed inwards from the surface are respectively arranged on the inner circumferential surface and the outer circumferential surface of the annular conveyor belt s30, wherein the upper trough s30a and the driving trough s30b have the same shape and structure. Thus, the front and back sides are universal as long as the belt is an annular belt, and the belt is very convenient to use and install in practice.

Meanwhile, in order to simplify the structure and only possibly reduce the dead weight, the support in the example is formed by splicing frame rods.

In this example, two endless belts s30 are arranged, and the two endless belts s30 are arranged between the first frame a 'and the second frame b' in parallel and aligned along the length direction of the truss s20, and at the same time, the feeding end of the endless belt s30 extends below the inclined surface; the discharge end extends outside the frame s 10.

The two annular conveyor belts s30 synchronously move, and meanwhile, the feeding grooves s30a on the two annular conveyor belts s30 are arranged in one-to-one correspondence, and each long bar B falling from the unloading channel X falls into the two feeding grooves s30a corresponding to the unloading channel X, so that the long bar B is supported and reloaded and positioned.

Specifically, the driving assembly s31 includes a driving wheel s310 and a driven wheel s311 that mate with the driving groove s30b of each endless conveyor belt s30, a synchronizing shaft s312 for synchronously connecting the adjacent two driving wheels s310, and a driving motor s313 and a transmission member s314 that drive the synchronizing shaft s312 to rotate about their own axes.

The transmission s314 may take the form of a pulley or gear-engagement transmission, which is not described in detail herein.

Meanwhile, in consideration of the different carrying capacities of the endless conveyor belt s30, tensioning of the endless belt by adjusting the distance between the driving wheel s310 and the driven wheel s311 is also a conventional means in the art, and will not be described in detail herein.

In this example, the number of the material grooves s30a on the upper surface of the endless conveyor belt s30 is greater than the number of the material supplies required by each processing apparatus, and the width of the unloading opening is equal to the outer diameter of the long bar to be fed. Therefore, a batch of material is generally fed and basically falls on the feeding groove of the corresponding horizontal section of the annular conveyor belt.

Meanwhile, it should be noted that in this example, the height of the unloading opening and the moving distance of the endless conveyor within a unit time are matched, that is, after each pitch slot distance of the endless conveyor, one long bar material is dropped from the unloading opening, so that a batch of long bar materials falls into each feeding slot passing below the unloading opening one by one.

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

1) The automatic feeding device further comprises a weighing mechanism (not shown in the figure, but not easily thought) which is arranged on the transfer trolley and used for weighing the long bars carried by each batch, when the weighing mechanism is communicated with the driving assembly, the weight of each time is reduced to be the weight of one long bar, when the weight is reduced to be equal to the total weight of the required feeding number, the driving assembly is switched to move reversely, and the long bars close to the output end are returned to the horizontal section of the annular conveyor belt. The purpose of setting like this can realize the feed of the required number stock of a batch, and unnecessary stock returns the horizontal segment of annular conveyor again simultaneously, makes things convenient for unnecessary stock to remove like this, prevents that the stock from leaving from annular conveyor discharge end portion and missing.

Meanwhile, the applicant needs to supplement that once the intermittent state occurs in the weighing process, the unloading port possibly jams, and 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 further comprises a counting mechanism which is communicated with the driving assembly, wherein the counting mechanism is used for counting the number of long bars transmitted from the annular conveyor belt, and when the number of the fed long bars is equal to the number of the required fed long bars, the driving assembly is switched to move reversely, and long bars close to the output end are returned to the horizontal section of the annular conveyor belt. Thus, the extra long bar is convenient to move, and the long bar is prevented from falling from the discharge end of the annular conveying belt.

In 2), as to how to realize statistics of the number of long bars coming out of the endless conveyor, a photoelectric sensor commonly used in the art can be adopted, when the photoelectric sensor senses that one long bar is discharged out of the endless conveyor, the photoelectric sensor counts once, and when the accumulated count number is equal to the number of the tertiary bars needing to be fed, the driving assembly is switched to move reversely, and the long bar near the output end is returned to the horizontal section of the endless conveyor. Or the time is calculated, the reason is very simple, because the moving speed of the annular conveyor belt is stable, a sensor is arranged at the output end part, once the long rod material starts to be counted when being discharged, the discharging is stopped and the reverse rotation is carried out after the set time is reached, and thus, the feeding can be quantitatively completed.

Similarly, once the intermittent operation occurs in the counting process, the unloading port can be blocked, and 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.

In the embodiment, the combination of the two means is adopted, so that mutual authentication is carried out between the two means, and feeding is more accurately finished.

Meanwhile, baffle assemblies s4 extending along the conveying direction of the long bar are arranged at two end parts of the truss s20, wherein the baffle assemblies s4 at the two end parts are symmetrically arranged.

Specifically, the baffle assembly s4 includes a closing plate s40 disposed perpendicular to the truss s20, and guide flaps s41 bent inward from both end portions of the closing plate s 40. In this case, the baffle assembly s4 is mainly configured to prevent sudden stop during the long rod transferring process, so that the possibility of unexpected transportation caused by flushing from the feeding trough is avoided. Meanwhile, under the action of the guide folded edge s41, long bars which are convenient for some dislocation can be smoothly jacked into the long bar bearing area.

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

a) Moving a transfer skip to the side of a discharging surface of the long bar material distributing device, correspondingly inserting the first frame body and the second frame body below the discharging surface, butting the discharging surface with the inclined surface, and freely rolling the long bar material into a long bar material bearing area with a closed discharging opening when the long bar material distributing device discharges in batches;

b) After material taking is completed, moving a transfer skip to a machine tool, butting the discharge end part of the annular conveyor belt with the feeding material of the machine tool, opening an unloading port and operating the annular conveyor belt, wherein long bar materials roll down from the unloading port to a feeding groove passing through the lower part of the unloading port one by one in sequence, and then conveying the long bar materials to the machine tool one by one under the operation of the annular conveyor belt;

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

Therefore, the application adopts batch feeding, namely, long bars are not required to be manually checked, the long bars are quantitatively conveyed to a processing center through a carrier, each long bar unloaded from an unloading port falls into a feeding groove below the unloading port in sequence under the movement of the feeding groove of the annular conveyor belt, and is fed to the feeding end part of a machine tool, meanwhile, once the quantity or the weight reaches the standard, the feeding is stopped, the annular conveyor belt is reversely rotated, the rest long bars are moved to the horizontal section above the annular conveyor belt, and then the rest long bars are transferred to other machine tools needing materials or are directly transported back to a stacking area, so that the feeding efficiency of the long bars can be greatly improved after batch and continuous batch feeding, and the machine tool is labor-saving and is not easy to make mistakes.

The present invention has been described in detail with the purpose of enabling those skilled in the art to understand the contents of the present invention and to implement the same, but not to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
