It is to be understood that the attitude of the bar 200 as described herein refers to the relative position of the sides of the bar 200 in space.

Further, the stacker further comprises a blanking device 4 configured to convey the bar stock 200 on the storage turntable 21 to the stacker. The stacking machine further comprises an electric control device which is configured to control the change of the space posture of the bar materials 200 and select the specific bar materials 200 on the storage turntable 21 to be conveyed to the stacking device for arrangement, so that the total width of the layered bar materials 200 is within a preset range.

The stacking machine further comprises a machine frame 100, and the detection device 1, the rotating device 5, the feeding device 3, the discharging device 4, the storage device 2, the stacking device and the material frame device 8 are all arranged on the machine frame 100.

Further, the stacking machine further comprises a display device, and the display device is configured to be capable of displaying the operation state of each device, so that the stacking process can be monitored manually in real time.

The embodiment further provides a stacking method, in which the stacking machine is used to stack the bar stock 200, and the method specifically includes the following steps:

s1: putting the bar 200 into the detection device 1 to detect the end face size of the bar 200;

s2: the bar material 200 is conveyed to a material storage turntable 21 through a feeding device 3 for storage;

s3: the blanking device 4 takes materials from the material storage device 2 and conveys the materials to the material stacking device, and the material stacking device arranges the bars 200 into layers;

s4: pushing the arranged layered bar stock 200 into a material frame 300 of a material frame device 8;

s5: and repeating the steps S3 and S4 to complete the stacking of the layered bar stock 200 in the material frame 300.

In specific implementation, in step S2, only the end face size of a certain number of bars 200 may be detected, and the end face size is stored in the storage device 2 without any rotation operation, and then a certain number of bars 200 are randomly selected to be arranged in a layered manner, and after the bars are arranged in a certain number, the electric control device selects the specific size of the bars 200 to be arranged subsequently according to the total width requirement of each layer of bars 200. Specifically, after the detection is completed, the detection device 1 transmits the size data of the bar 200 to the electric control device, so that the electric control device calculates to obtain whether the size of the subsequent bar 200 meets the requirement for arrangement, and if the size of the bar 200 cannot meet the requirement, the feeding device 3 is used for storing the bar 200 on the storage turntable 21 for standby; if the size of the bar 200 is sufficient, the bar 200 is deemed to be usable.

The method between the steps S1 and S2 may further include the steps of:

s11: the rotating device 5 selectively changes the spatial attitude of the bar material 200;

if the electric control device recognizes that a certain bar 200 is available and the posture of the bar 200 on the detection device 1 is just the posture required for arrangement, the bar 200 is placed on the storage turntable 21 only by the direct operation of the feeding device 3 and then taken out by the discharging device 4 for arrangement; however, if the posture of the bar 200 on the detecting device 1 needs to be changed as required, the rotating device 5 needs to rotate the bar 200, so that the bar 200 is stored in the storage turntable 21 in a specific posture and kept in the posture until the arrangement is completed. So, can guarantee naturally that the total width of every layer of bar 200 is at certain predetermined range, bar 200 can pile up in the material frame 300 just and do not take place to rock and loose, guarantees the regularity and the stability of piling up. Of course, in specific implementation, the electronic control device can also select the bar stock 200 with the required posture and size from the bar stocks 200 stored on the storage turntable 21. Further, the material storage device 2 comprises at least two material storage rotating discs 21, the two material storage rotating discs 21 are arranged, the storage capacity is improved, and the electric control device can select from a larger database, so that the proper bars 200 can be selected more easily to be arranged, and the stacking efficiency is improved.

According to the material stacking machine and the material stacking method provided by the embodiment, the automatic stacking of the bars 200 is realized by arranging the detection device 1, the feeding device 3, the storage device 2, the discharging device 4 and the material stacking device, so that the stacking efficiency is improved; meanwhile, the rotating device 5 is arranged between the detection device 1 and the feeding device 3, so that the space posture of the bars 200 is changed, the total width of each layer of stacked bars 200 is in a preset range, the bars 200 are stably stacked in the material frame 300, and the convenience of later-stage transportation and use is improved; the arrangement of the two material storage turntables 21 improves the stock base number of the bar material 200, and the stacking is completed efficiently.

Alternatively, in this embodiment, the bar 200 to be stacked is a regular hexagonal prism structure, and the end surface of the bar 200 is a regular hexagon, which cannot be guaranteed due to the problem of manufacturing error, so that the bar 200 can change its posture under the operation of the rotating device 5 according to the instruction of the electric control device, so that the six side surfaces of the bar can change their spatial positions according to the arrangement requirement. Further, for the bars 200 with the regular hexagonal prism structure, in order to stack more bars 200 as much as possible, the total number of the bars 200 of the two adjacent layers of bars 200 should be different by 1, and the number of the bars 200 at the bottom layer is more than that of the bars 200 at the last but one layer, so except for the bars 200 at the top layer and the bottom layer and the edge bars 200 of the layered bars 200 with more total number, each bar 200 is arranged between the two adjacent bars 200 at the lower layer and the upper layer, and the side surfaces are mutually attached, which is beneficial to the regular arrangement of the bars 200, effectively utilizes the regular hexagonal prism structure of the bars 200 to improve the space utilization rate of the material frame 300, and can avoid the problems that the bars 200 shake in the material frame 300, cause disordered arrangement, and are not beneficial to later-stage transportation and use. For the bars 200 with a regular hexagonal prism structure, the total number of the bars 200 in each layer can be 70 or 71, and of course, the total number of the bars 200 in each layer and the total width thereof can be adjusted according to the structure of a specific product and the size of the storage space of the material frame 300, which is just an example. It should be noted that the stacker in this embodiment can be used for stacking bars 200 having a regular hexagonal prism structure, but is not limited to stacking bars 200 having a regular hexagonal prism structure, and may also be used for stacking bars 200 having other structures, such as a rectangular parallelepiped, a regular triangular prism, and the like, and the specific stacking principle is similar to that in this embodiment, the description is mainly given by taking bars 200 having a regular hexagonal prism structure as an example.

In specific implementation, after the image acquisition assembly 12 on one side finishes the end face image acquisition of the bar 200, if the rotating device 5 is required to adjust the posture of the bar 200, the rotating clamping jaw 51 is driven by the first driving module 53 to move towards the carrier 11 until one end of the bar 200 placed on the carrier 11 can be clamped; subsequently, the sliding plate 14 of the carrier 11 is driven by the first driving mechanism 15 to move away from the fixed plate 111, so that the bar 200 is separated from the limit of the limiting member 141; then, the fixing plate 111 moves in the direction of the upper material level under the driving of the detection driving module 13, the bar 200 is released, and the bar 200 rotates under the driving of the rotation driving mechanism 52 until the posture meets the requirement; finally, the feeding device 3 transfers the bar 200 from the rotating device 5 to the storing device 2.

If the bar 200 does not need to be changed in posture, the bar 200 can be directly transported from the carrier 11 to the stocker 2 by the feeding device 3. Therefore, the present embodiment further provides a feeding device that can be used in the above-mentioned stacker. Referring to fig. 9, the feeding device 3 includes a feeding clamping jaw 31, a feeding driving module 32 and a feeding mounting frame 33, the feeding mounting frame 33 is disposed on the rack 100, the feeding driving module 32 is disposed on the feeding mounting frame 33, and an output end of the feeding driving module is connected to the feeding clamping jaw 31, so as to realize displacement of the feeding clamping jaw 31 in a first direction, a second direction and a vertical direction. Optionally, the feeding driving module 32 is a combination of a sliding table cylinder and a cylinder module, wherein the cylinder module is used for realizing the movement of the feeding clamping jaw 31 along the vertical direction, and the sliding table cylinder is used for realizing the movement of the feeding clamping jaw 31 along the first direction and the second direction. Alternatively, the feeding gripper 31 is a thin pneumatic gripper. Further, the feeding mounting frame 33 extends along a first direction, and the feeding clamping claws 31 move along the first direction under the driving of the feeding driving module 32, so that the bar stock 200 can be fed to any one of the two storage turntables 21; because the storage turntable 21 and the detection device 1 (or the rotating device 5) have an interval in the second direction, the feeding driving module 32 can also drive the feeding clamping claw 31 to move along the second direction, and the feeding process is completed by moving back and forth between the storage turntable 21 and the detection device 1 (or the rotating device 5); further, the feeding clamping claw 31 can also move in the vertical direction under the driving of the feeding driving module 32, so that the clamping and the placing of the bar 200 are realized. Optionally, the loading mount 33 is a gate mount that is disposed across the rack 100 in a first direction.

Further alternatively, in this embodiment, since the bars 200 on the detecting device 1 and the rotating device 5 extend along the first direction, when the feeding device 3 and the discharging device 4 are respectively located at two sides of the storage turntable 21 along the second direction, the feeding clamping claw 31 still maintains the state that the bars 200 extend along the first direction when the bars 200 are taken out from the carrier 11 or the rotating clamping claw 51, but the accommodating groove 213 on the storage turntable 21 extends along the radial direction of the storage turntable 21 when rotating to the feeding device 3, and therefore forms an included angle or overlaps with the second direction. In order to ensure that the bar 200 can be placed into the accommodating groove 213, the feeding device 3 further includes a second motor 34, a main body of the second motor 34 is connected with an output end of the feeding driving module 32 through a motor mounting plate 35, an output end of the second motor 34 is connected with the feeding clamping claw 31, and then the feeding clamping claw 31 is driven to rotate until the bar 200 clamped by the feeding clamping claw is matched and corresponds to the accommodating groove 213 in the vertical direction, so as to keep the extending direction consistent, and then the feeding driving module 32 drives the feeding clamping claw 31 to descend along the third direction, so that the bar 200 is just placed into the accommodating groove 213.

The embodiment also provides a blanking device which can be used in the stacking machine. Referring to fig. 10, the blanking device 4 includes a blanking clamping jaw 41, a blanking driving module 42 and a blanking mounting bracket 43, the blanking mounting bracket 43 is disposed on the frame 100, the blanking driving module 42 is disposed on the blanking mounting bracket 43, and an output end of the blanking driving module is connected to the blanking clamping jaw 41, so as to realize displacement of the blanking clamping jaw 41 in the horizontal direction and the vertical direction. Optionally, in this embodiment, the blanking driving module 42 is mainly used for realizing displacement of the blanking clamping jaw 41 in the first direction and the vertical direction. Optionally, the blanking driving module 42 is also a combination of a sliding table cylinder and a cylinder module, wherein the sliding table cylinder is arranged on a sliding table of the cylinder module; the cylinder module is used for realizing the removal of unloading clamping jaw 41 along first direction, and the output and the unloading clamping jaw 41 of slip table cylinder are connected to realize the removal of unloading clamping jaw 41 along vertical direction. Optionally, the blanking clamping jaw 41 also adopts a thin type pneumatic jaw. Further, the blanking mounting frame 43 extends along the first direction, and the blanking clamping jaw 41 moves along the first direction under the driving of the blanking driving module 42, so that the bar 200 on any one of the two storage turntables 21 can be taken out; further, the feeding clamping jaw 31 can also move in the vertical direction under the driving of the feeding driving module 42, so as to take out or pinch the bar 200 from the storage turntable 21 to the stacking device. Optionally, the blanking mount 43 is also a gate mount, which is disposed across the frame 100 in a first direction.

Further optionally, the blanking device 4 further includes a third motor 44, a main body of the third motor 44 is connected to an output end of the blanking driving module 42, and an output end of the third motor 44 is connected to the blanking clamping jaw 41, so as to drive the blanking clamping jaw 41 to rotate. The main reasons for providing the third motor 44 are: since the feeding jaw 41 still maintains the specific extending direction (the second direction in the present embodiment) when the bar material 200 is taken out from the storage tray 212, but the stacking machine needs to satisfy the requirement of compactness in design, the extending direction of the bar material 200 when the bar material 200 is pushed into the stacking device does not necessarily coincide with the extending direction of the bar material 200 when the bar material 200 is taken out from the accommodating groove 213, and therefore, the third motor 44 needs to rotate the bar material 200 to satisfy the requirement of the stacking device on the extending direction of the bar material 200.

The position that loading attachment 3 and unloader 4 that this embodiment provided is relatively fixed, and the rotation mainly through carousel body 211 is supplementary to realize the material loading of bar 200 and the getting of specific bar 200, has avoided loading attachment 3 and unloader 4 to produce and has removed on a large scale, and structural design is simple, the simple operation.

It can be understood that, as shown in the first embodiment, the step of arranging the bars 200 into layers is an important step in stacking the bars 200.

Referring to fig. 11, the feeding device 6 includes a conveying mechanism 61 for receiving the bar material 200 conveyed by the blanking device 4 and conveying the bar material to the clip device 7. The conveying mechanism 61 includes: a conveying clamping jaw 611 used for clamping the bar stock 200, and a second driving module 612 used for driving the conveying clamping jaw 611 to move towards the direction of the cartridge clamping device 7. Further, the conveying mechanism 61 is arranged on the rack 100 through a conveying mounting frame 615, the second driving module 612 is arranged on the conveying mounting frame 615, and a sliding table of the second driving module 612 is connected with the conveying clamping jaw 611. Wherein the second drive module 612 may optionally be a pneumatic module. Further, the conveying mechanism 61 further includes a first laser displacement sensor 613 disposed on the sliding table of the second driving module 612, and a third driving module 614 disposed between the conveying clamping jaw 611 and the sliding table of the second driving module 612, the first laser displacement sensor 613 can move to the vicinity of the clip device 7 along with the conveying clamping jaw 611, and measure the distance of the closest bar 200 on the clip loading mechanism 71, so as to obtain the distance that the conveying clamping jaw 611 needs to continue to advance, after the calculation is completed, the conveying clamping jaw 611 pushes the bar 200 into the clip loading mechanism 71 under the driving of the third driving module 614, and fits with the closest bar 200 in the clip loading mechanism 71, thereby completing the layered arrangement. Alternatively, the third driving module 614 may be a sliding table cylinder. Alternatively, in the present embodiment, the conveying mechanism 61 is provided between the two magazine disks 21.

As can be seen from the fourth embodiment, the blanking device 4 can drive the blanking clamping jaw 41 to rotate, so as to change the extending direction of the bar material 200 in the space, for convenience of describing the material stacking process of the material stacking device, in this embodiment, the blanking device 4 rotates the bar material 200 to extend along the first direction, and then conveys the bar material 200 to the conveying mechanism 61, and the conveying mechanism 61 conveys the bar material 200 to the clip device 7 along the second direction. That is, in the present embodiment, the layered bars 200 are arranged in the second direction, and each bar 200 extends in the first direction. Of course, in practical implementation, the extending direction of the bar material 200 on the conveying mechanism 61 is not limited to the above arrangement, and can be flexibly changed according to the arrangement of the spring loading device 6, the clip device 7 and the frame device 8 on the rack 100 in different directions.

In particular, with reference again to fig. 11, the delivery jaw 611 comprises an upper jaw 6111 and a lower jaw 6112, which can be relatively close to or far from each other, the upper jaw 6111 and the lower jaw 6112 being able to clamp the bar 200 close to each other; the lower end of the upper clamping jaw 6111 and the upper end of the lower clamping jaw 6112 are respectively provided with a second clamping groove and a third clamping groove, when the upper clamping jaw 6111 and the lower clamping jaw 6112 are close to each other, the second clamping groove and the third clamping groove form a space matched with the structure of the bar material 200, and the bar material 200 can be clamped in the space to ensure the stability of the bar material 200 in the conveying process. Further specifically, the upper jaw 6111 and the lower jaw 6112 are both U-shaped, and the bar material 200 is clamped at the free end of the U-shaped. In specific implementation, the blanking clamping jaw 41 clamps the bar material 200 from the material storage turntable 21, moves to the upper part of the conveying mechanism 61 along the first direction, and then descends to the conveying clamping jaw 611 along the vertical direction under the driving of the blanking driving module 42; the upper clamping jaw 6111 and the lower clamping jaw 6112 of the conveying clamping jaw 611 are far away from each other, and the conveying clamping jaw 611 is driven to be close to the bar stock 200 through the third driving module 614 until the bar stock 200 can be placed in the third clamping groove on the lower clamping jaw 6112; loosening the blanking clamping jaw 41 and keeping away from the conveying mechanism 61; the upper jaw 6111 approaches the lower jaw 6112 until the bar 200 is clamped, i.e. the bar 200 is transported from the magazine 2 to the transport mechanism 61. Preferably, the upper jaw 6111 and the lower jaw 6112 are designed to be U-shaped, so as to accommodate the blanking jaw 41, and avoid interference with the blanking jaw 41 in the above process. Preferably, the second driving module 612 and the third driving module 614 on the conveying mechanism 61 can both realize the movement of the conveying clamping jaw 611 along the second direction, so that the position of the blanking clamping jaw 41 is not required to be adjusted in the second direction, the structure of the blanking device 4 is simplified, and the design of the stacking machine is optimized.

Referring to fig. 12 and 13, the clip loading mechanism 71 includes a clip 711, the bars 200 conveyed by the conveying mechanism 61 sequentially enter the clip 711 to complete alignment, the clip 711 specifically includes an upper cover plate and a lower cover plate which are arranged at intervals, a storage space for the bars 200 is provided between the upper cover plate and the lower cover plate, and the height of the storage space should be greater than the height of the bars 200 to accommodate the aligned bars 200. Further, in order to realize the sequential arrangement of the bars 200, the clip loading mechanism 71 further includes a reverse stopping mechanism 712 and an elastic stopping mechanism, which are respectively located at two ends of the clip 711 along the arrangement direction (in this embodiment, the second direction), wherein the reverse stopping mechanism 712 is located at the inlet end of the clip 711, and the layered bars 200 in the clip 711 are always kept tightly attached without shaking or rolling through the cooperation of the reverse stopping mechanism 712 and the elastic stopping mechanism until the final layered arrangement is completed.

Further, referring to fig. 12, the clip loading mechanism 71 further includes a second laser displacement sensor 713 disposed on the clip 711, which cooperates with the first laser displacement sensor 613 for detecting the total width of the whole layered bar material 200, and when the total width reaches a preset range, the feeding device 6 stops feeding the bar material 200. Specifically, the second laser displacement sensor 713 is used for performing coordinate positioning on the bar 200 entering the clip 711 first, and the first laser displacement sensor 613 is used for performing coordinate positioning on the bar 200 entering the clip 711 last, so as to measure the total width of the whole laminated bar 200.

Referring to fig. 12 and 13, the pushing mechanism 72 includes a push plate 721 and a fourth driving module 722, the push plate 721 is disposed opposite to the layered bar 200 in the clip loading mechanism 71, and the fourth driving module 722 is configured to drive the push plate 721 to abut against one end surface of the layered bar 200, so as to push the entire layered bar 200 to move toward the inside of the material frame 300. The fourth drive module 722 may alternatively be a pneumatic module. Further, the width of the push plate 721 should be consistent with the total width of the layered bar 200 to ensure that all the bar 200 of the layered bar 200 are abutted, so that the total width of the layered bar 200 may be varied according to the stacked products and the size and structure of the products, and therefore at least two push plates 721 with different widths and corresponding fourth driving modules 722 may be optionally provided to respectively push the layered bars 200 with different total width sizes. In this embodiment, for the bar material 200 having a regular hexagonal prism structure, the number of the bar materials 200 arranged in two adjacent layers differs by 1, so the total width of the layered bar material 200 mainly has two sizes, and accordingly, the number of the push plate 721 and the number of the fourth driving module 722 are both set to two. Further, since the positions of the frame 300 and the clip loading mechanism 71 on the frame 100 are relatively fixed, the clip device 7 further includes a fifth driving module 73 for driving the pushing mechanism 72 to move along the width direction of the laminated bar material 200, so that the pushing plates 721 with different width dimensions correspond to the laminated bar material 200 with corresponding total width, and the laminated bar material 200 is further pushed into the same frame 300. In this embodiment, the push plate 721 can push the bar material 200 into the frame 300 along the first direction under the driving of the fourth driving module 722; the pushing mechanism 72 can be driven by the fifth driving module 73 to move along the second direction.

Further, the width of the clip 711 is smaller than the length of the bar 200, so that the two free ends of the bar 200 can be arranged to protrude out of the clip 711, which is convenient for pushing the bar 200 by the conveying clamping jaw 611, and is also convenient for the push plate 721 to abut against the bar 200 to complete pushing. In this embodiment, the width of the clip 711 is smaller than the distance between the two free ends of the U-shaped structure of the upper jaw 6111 and the lower jaw 6112, so that the feeding jaw 611 is not interfered when pushing the bar stock 200 into the clip 711, and the bar stock 200 is pushed into the clip 711 along the arrangement direction until the clip is attached to the nearest bar stock 200.

Further, since the length and the size of the bars 200 are substantially the same, in order to ensure that the end surfaces of the plurality of bars 200 are flush when the stacking device performs the layered arrangement, the feeding clamping jaw 31 and the discharging clamping jaw 41 are used for clamping specific parts of the bars 200, and further, the problem that whether the end surfaces are flush is considered when each layer of the bars 200 are arranged differently. In order to achieve the above purpose, referring to fig. 5 and 7, a yielding groove 214 is formed near each of the receiving grooves 213 of the fixing plate 111, the sliding plate 14 and the storage tray 212 of the detecting device 1, the positions of the yielding grooves 214 relative to the bar 200 are kept consistent, and the feeding clamping jaw 31 and the discharging clamping jaw 41 extend into the corresponding yielding grooves 214 to clamp the bar 200 at fixed positions.
