In this example, a plurality of feeding grooves 30a extending along the direction of the width of the annular conveyor belt are uniformly distributed on the circumferential surface of the annular conveyor belt 30, the feeding grooves 30a 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 30 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 machine tool feeding center one by one from the discharging end under the transmission of the annular conveyor belt.
Meanwhile, an upper trough 30a and a driving trough 30b are respectively arranged on the inner circumferential surface and the outer circumferential surface of the annular conveyor belt 30, and the upper trough 30a and the driving trough 30b are identical in 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.

Specifically, the driving assembly 31 includes a driving wheel 310 and a driven wheel 311 which are matingly abutted with the driving groove 30b of each endless conveyor 30, a synchronizing shaft 312 for synchronously connecting the adjacent two driving wheels 310, and a driving motor 313 and a transmission 314 which drive the synchronizing shaft 312 to rotate about their own axes.
The drive 314 may take the form of a pulley or gear engagement drive, which is not described in detail herein.
Meanwhile, the tensioning of the endless belt by adjusting the distance between the driving wheel 310 and the driven wheel 311 is also a conventional means in the art in consideration of the different carrying capacities of the endless belt 30, which will not be described in detail herein.
In this example, the number of the feed grooves 30a on the upper surface of the endless conveyor 30 is larger than the number of the feed materials required for 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 mechanism 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 mechanism 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 4 extending along the conveying direction of the long bar are provided at both end portions of the truss 20, wherein the baffle assemblies 4 at both end portions are symmetrically arranged.
Specifically, the baffle assembly 4 includes a sealing plate 40 disposed perpendicular to the truss 20, and guide flaps 41 bent inward from both end portions of the sealing plate 40. In this case, the baffle assembly 4 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 41, 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 batch feeding is adopted, that is, manual counting is not needed, long bars are manually moved, then 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 passing through the lower part of the unloading in sequence under the motion of a feeding groove of an annular conveying 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 conveying belt is reversely rotated, the rest long bars are moved to a horizontal section above the annular conveying belt, then the rest long bars are conveyed to other machine tools needing materials or are directly transported back to roll to a stacking area, and in this way, the feeding efficiency of the long bars can be greatly improved after the feeding of batches and continuous batches, the machine tool is labor-saving, and the machine tool is not prone to error.
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.
