However, this is very easy to implement in the enterprise, and is also a conventional means (such as control of magnetic channel, etc.), and will not be explained here.

Referring to fig. 2 and 3, the long bar stock carrier unit 2 includes a truss 20 fixed on the frame 10 and extending along the length direction of the long bar stock B, and a support frame 21 located at one side of the truss 20 and forming a long bar stock carrying area, wherein two ends of the truss 20 extend out of two sides of the frame 10 and have a length greater than that of the long bar stock B.

The supporting frame 21 comprises a frame base 210 fixed on the frame 10 and having a feeding end and a discharging end, a baffle 211 arranged at the discharging end of the frame base 210, and a gate assembly 212 movably arranged on the truss 20 and capable of opening or closing an unloading opening formed by the baffle 211 and the discharging end of the frame base 210, wherein the feeding end of the frame base 210 is butted with an unloading surface of the long rod material distribution device, and after the unloading opening is opened by the gate assembly 212, long rod materials B are unloaded from the unloading opening one by one to form a long rod material bearing area.

That is, the opening and closing of the discharge port in this example is determined by the size of the opening (also referred to as discharge port) of the gate assembly 212, and once the width of the opening is greater than or equal to the outer diameter of the long billet B, the discharge port is in an open state.

Meanwhile, in the embodiment, in order to realize two technical purposes of discharging one by one and preventing material blockage, two discharging procedures are adopted, and the method is specifically implemented as follows.

The upper surface of the frame base 210 is formed with a bearing surface extending from the outside of the transfer cart to the inside from top to bottom, wherein the bearing surface is connected with the unloading surface from the upper end, and the long rod material freely rolling down from the unloading surface rolls to the unloading opening at the lower part along the bearing surface for stacking.

Thus, the structure can be greatly simplified and the self weight can be reduced.

The baffle 211 includes a first baffle c and a second baffle d, which are disposed in a one-to-one correspondence with the first frame a and the second frame b and disposed on the truss 20, wherein the first baffle c and the second baffle d are symmetrically disposed.

The gate assembly 212 includes a first gate e and a second gate f disposed at one side of the first frame a and the second frame b, and a first driver g and a second driver h for driving the first gate e and the second gate f to move, respectively, wherein the first gate e and the first driver g are in one group, the second gate f and the second driver h are in another group, and the two groups move symmetrically and synchronously.

Specifically, a first baffle plate c and a second baffle plate d are respectively positioned above the oblique sides of a first frame body a and a second frame body b, and a first discharge opening K1 is formed among the first baffle plate c, the first frame body a and a first gate e; a second discharge opening K2 is formed among the second baffle plate d, the second frame body b and the second gate f; the first discharge port K1 and the second discharge port K2 are symmetrically arranged and constitute the discharge port K. 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 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 bevel edge of the first frame body a, the first gate e is positioned above the discharging space and horizontally arranged, and after the first gate e moves towards the feeding end part of the first frame body a horizontally, the first discharging opening K1 is opened.

The first gate e comprises a first gate seat e1 positioned on the truss 20, a first slide seat e2 horizontally arranged on the first gate seat e1 along the direction perpendicular to the length direction of the long bar B, a first supporting round rod e3 fixedly arranged on the first slide seat e2 and extending along the length direction of the first slide seat e2, wherein the first supporting bar e3 is circular in cross section, and the upper part of the circle protrudes upwards out of the first slide seat e2 and forms part of the first discharge opening K1, so that the contact area with the long bar B is small, and the opening and closing operation of the discharge opening K is facilitated, the first actuator g is used to push the first slide e2 to move on the first gate e1, when the first discharge port K1 is closed (as shown in connection with fig. 4), the long bar stock B is bridged on the first support rod e3, when the first discharge opening K1 is opened and the size of the gap formed is equal to the outer diameter of the long billet B (shown in connection with fig. 5), the long billet B rolls out of the first discharge opening K1.

According to the principle of symmetry, the second baffle d is also vertically arranged, a discharging space for a long rod to fall is formed between the lower end part of the second baffle d and the bevel edge of the second frame body b, the second gate f is positioned above the discharging space and horizontally arranged, and after the second gate f moves horizontally to the feeding end part of the second frame body b, the second discharging opening K2 is opened.

In this example, the first driver g and the second driver h have the same structure, are both telescopic rods, and have power of hydraulic pressure, electric power or pneumatic power.

The second gate f comprises a second gate seat f1 positioned on the truss 20, a second slide seat f2 horizontally arranged on the second gate seat f1 along the direction perpendicular to the length direction of the long bar B, a second supporting rod f3 fixedly arranged on the second slide seat f2 and extending along the length direction of the second slide seat f2, wherein the section of the second supporting rod f3 is circular, the upper part of the circular shape protrudes upwards out of the second slide seat f2 and forms a part of a second discharging opening K2, and a second driver h is used for pushing the second slide seat f2 to move on the second gate seat f 1.

That is, under the driving of the first driver g and the second driver h which move synchronously, the first discharge opening K1 and the second discharge opening K2 move synchronously, so that the discharge openings are opened, the width of the discharge openings is equal to the outer diameter of the long rod materials, and at this time, the long rod materials are discharged from the discharge openings one by one and form a first 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 further opening and the closed motion of first gate e and second gate f, 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.

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

The baffle 211 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 example is unloaded from the discharge port K to the discharge passage X, and then discharged from the bottom of the discharge passage X. 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 3 comprises an endless conveyor 30 arranged on the other side of the truss 20 and horizontally arranged on the frame 10, and a driving assembly 31 for driving the endless conveyor 30 to rotate, wherein the feeding end (right end) of the endless conveyor 30 is positioned below the unloading channel X, and the discharging end (left end) protrudes from the opposite side of the frame 10 corresponding to the support frame 21.

In this example, a plurality of feeding troughs 30a extending along the width direction of the endless conveyor belt are uniformly distributed on the circumferential surface of the endless conveyor belt 30, the feeding troughs 30a are matched with long bars to be fed, when a specified machine tool needs to be fed, the discharging end part of the endless conveyor belt 30 is inserted into the machine tool for feeding, after an unloading opening is opened, the long bars drop into the corresponding feeding troughs 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 part under the transmission of the endless conveyor belt.

Meanwhile, an upper trough 30a and a driving trough 30b which are recessed inwards from the surface are respectively arranged on the inner circumferential surface and the outer circumferential surface of the endless conveyor 30, wherein the upper trough 30a and the driving trough 30b are the same in 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 30, and the two endless conveyors 30 are distributed between the first frame a and the second frame b in parallel and aligned along the length direction of the truss 20, and at the same time, the feeding end of the endless conveyor 30 extends to the lower part of the inclined plane; the discharge end extends outside the frame 10.

The two endless conveyors 30 move synchronously, the feeding troughs 30a on the two endless conveyors 30 are arranged in one-to-one correspondence, and each long bar B falling from the unloading channel X falls into the two feeding troughs 30a corresponding thereto, so that the long bar B is supported and transshipped and positioned.

Specifically, the driving assembly 31 includes a driving wheel 310 and a driven wheel 311 which are in matching engagement with the driving groove 30b of each endless transmission belt 30, a synchronizing shaft 312 for synchronously connecting the adjacent two driving wheels 310, and a driving motor 313 and a transmission member 314 for driving the synchronizing shaft 312 to rotate about its axis.

The transmission 314 may take the form of a pulley or gear mesh transmission and 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 310 and the driven pulley 311 so as to tension the endless belt in consideration of the different load-bearing capacities of the endless transmission belt 30, and it will not be described in detail herein.

In this case, the number of the troughs 30a of the endless conveyor 30 on the upper surface is greater than the number of feeds required for each processing device, 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 mechanism also comprises a weighing mechanism (not shown in the figure, but not difficult to think) which is arranged on the transfer trolley and used for weighing long bars loaded in each batch, when the weighing mechanism is communicated with the driving assembly, 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 the 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 mechanism 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 fed 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.
