Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubber mixing, and in particular to a feeding head and a feeding device. BACKGROUND

[0002] In the feeding process of the rubber mixing machine, the rubber is needed to be put into the feeding port of the rubber mixing machine. This process is often assisted by a mechanical hand to cooperate with a vacuum chuck to carry the rubber. However, because the rubber is relatively soft and has protrusions and / or depressions on the surface, it is not easy to arrange the rubber neatly in the frame. Therefore, the rubber needs to be arranged by hand before feeding, and then the rubber is sucked up by the vacuum chuck, which reduces the feeding efficiency of the rubber. For some uneven rubber, the vacuum chuck cannot adsorb it. At this time, the rubber block has to be carried to the feeding port by hand, which further reduces the overall feeding efficiency and also causes safety hazards.

[0003] Therefore, the above problems need to be solved. SUMMARY

In addition, the terms "first" and "second" are only used to distinguish in description and have no special meaning.

[0050] Please refer to Figures 1 to 5In the embodiment, the feeding device includes a transplanting mechanism, a feeding head, and a visual positioning mechanism. The feeding head is arranged at the transplanting end of the transplanting mechanism. The visual positioning mechanism is arranged on the feeding head and electrically connected with the transplanting mechanism to position the rubber material 100. It can be understood that the rubber material 100 is in the frame before feeding. Due to the uneven surface, the rubber material 100 is scattered in the frame and arranged in different postures. The visual positioning mechanism is used to position each rubber material 100. The visual positioning mechanism is preferably a CCD camera or an infrared visual positioning system in the prior art. After the position information of one rubber material 100 to be fed is obtained, a signal can be sent to the transplanting mechanism. Under the action of the transplanting mechanism, the feeding head can be directly opposite and the rubber material can be taken. The transplanting mechanism is preferably a multi-axis robot in the prior art. Then the transplanting mechanism can transplant the rubber material 100 to the feeding port of the internal mixer and put the rubber material 100 into the feeding port.

[0051] The feeding device is used to take the irregular rubber material 100 by the feeding head without manual assistance, thereby improving the feeding efficiency of the rubber material 100.

[0052] Based on the above, the feeding head in the embodiment includes a mounting seat 1, a rotating mechanism 2, a material taking part, and a material limiting mechanism 5. The rotating mechanism 2 is arranged on the mounting seat 1. The material taking part includes a center needle body 3 and a spiral blade 4 surrounding the center needle body 3. The rotating mechanism 2 is configured to drive the material taking part to rotate forward, so that the material taking part is screwed into the rubber material 100, thereby making the spiral blade 4 threadedly engaged with the rubber material 100. The material limiting mechanism 5 is used to abut and limit the rotation of the rubber material 100 when the rotating mechanism 2 drives the center needle body 3 to rotate reversely, so that the material taking part is screwed out of the rubber material 100.

[0053] It can be understood that the rotating mechanism 2 is arranged at the transplanting end of the transplanting mechanism through the mounting seat 1, the visual positioning mechanism can send a signal to the transplanting mechanism after positioning the rubber material 100, the transplanting mechanism can drive the material taking part to move close to the rubber material 100, and with the continuous action of the transplanting mechanism, the center needle body 3 abuts against the rubber material 100 and penetrates into the rubber material 100 to form positioning, then, under the cooperation of the rotating mechanism 2 and the transplanting mechanism, the material taking part is driven to rotate forward, and the material taking part is rotated into the inside of the rubber material 100, so that the spiral blade 4 is engaged with the rubber material, thereby avoiding the rubber material 100 from being separated from the center needle body 3. Compared with vacuum adsorption, the cooperation of the center needle body 3 and the spiral blade 4 does not need to consider the flatness of the rubber material 100, so that manual adjustment of the rubber material 100 is not needed, and the rubber material 100 can be moved to the above of the feeding port under the action of the transplanting mechanism, then, the limiting mechanism 5 limits the circumferential direction of the rubber material 100, so as to limit the rubber material 100 from rotating with the material taking part when the material taking part is driven to rotate reversely by the rotating mechanism, thereby making the rubber material 100 gradually separate from the center needle body 3. The whole process does not need manual participation, and the feeding efficiency of the rubber material 100 can be improved.

[0054] In the embodiment, the limiting mechanism 5 includes a connecting plate 51 and a plurality of limiting nails 52, the connecting plate 51 is opposite to the rubber material 100; the limiting nails 52 are arranged on the side of the connecting plate 51 facing the rubber material 100; a driving mechanism 53 is connected with the connecting plate 51 and is used for driving the connecting plate 51 to move close to the rubber material 100 when the center needle body 3 reversely rotates, so that the limiting nails 52 are inserted into the rubber material 100. It can be understood that, with the continuous forward rotation of the material taking part, the rubber material can be gradually moved from the needle head position of the center needle body 3 to the needle tail position under the action of the spiral blade 4, and can gradually move close to the connecting plate 51, before the rotating mechanism 2 reverses, the connecting plate 51 can be driven to move close to the rubber material 100 by the driving mechanism 53, and the limiting nails 52 can be inserted into the rubber material 100, the limiting nails 52 can limit the rubber material 100 from rotating around the axis of the center needle body 3 in the process of reverse rotation of the spiral blade 4, thereby driving the rubber material 100 to move along the axial direction of the center needle body 3, so that the rubber material 100 is separated from the material taking part, and the feeding of the rubber material 100 is completed.

[0055] It should be noted that, in order to ensure that the rubber material 100 can be separated from the center needle body 3, it should be ensured that the connecting plate 51 and / or the limiting nails 52 abut against the rubber material 100, so that the limiting mechanism 5 can always limit the circumferential direction of the rubber material 100 in the discharging process.

[0056] Exemplarily, the rotating mechanism 2 is a rotating motor in the prior art, which comprises a housing 21 arranged on the mounting base 1, a rotor arranged inside the housing 21, a stator arranged inside the housing 21, and a chuck 22 arranged on the rotor, the rotor and the stator are cooperated to enable the rotor to rotate around its own axis, and the chuck 22 is used to lock the needle tail, so that the central needle body 3 rotates synchronously with the rotor. The specific structure and use steps of the rotor, the stator and the chuck 22 are all in the prior art, so they are not described here.

[0057] The driving mechanism 53 comprises at least two first linear driving members 531, and any first linear driving member 531 is fixed on the housing 21, so as to improve the compactness of the feeding head, and the driving ends of the two first linear driving members 531 are connected with the connecting plate 51, so as to ensure that each limiting pin 52 can be stably inserted into the rubber material 100.

[0058] In addition, the limiting pin 52 is conical. It can be understood that the pointed top of the conical limiting pin 52 is directed towards the rubber material 100, so as to facilitate the insertion of the limiting pin 52 into the rubber material 100, and after the rubber material 100 is separated from the spiral blade 4, only gravity exists in the axial direction of the central needle body 3, under the action of the gravity, the rubber material 100 can be separated from the central needle body 3 and the limiting pin 52, and the conical limiting pin 52 can further prevent the rubber material 100 from adhering to the limiting pin 52 under the action of its own taper.

[0059] Further, the limiting pin 52 is provided at least two, and the increase of the number of limiting pins 52 can further increase the limitation of the rubber material.

[0060] It should be noted that the rubber material will be broken after entering the internal mixer, therefore, the damage of the material taking part and the limiting pin 52 to the rubber material will not affect the subsequent mixing.

[0061] In the embodiment, the connecting plate 51 has a avoiding hole 511 for the central needle body 3 to pass through, which is arranged in this way, so that a connecting plate 51 with a larger area can be selected, thereby increasing the contact area between the connecting plate 51 and the rubber material 100, and all the first linear driving members 531 are uniformly distributed with the axis of the avoiding hole 511 as the center line. It can be understood that all the first linear driving members 531 are fixed on different side walls of the housing 21, so as to ensure that the connecting plate 51 receives a relatively uniform thrust. Among them, the first linear driving member 531 is preferably a linear cylinder in the prior art, which can keep the connecting plate 51 and / or the limiting pin 52 in abutment with the rubber material 100 during the movement from the starting position to the terminal position.

[0062] Further, the shell 21 is provided with a limiting column on the side facing the rubber material 100; the connecting plate 51 is between the shell 21 and the rubber material 100 and has a limiting hole which is adapted to be positioned with the limiting column, and the depth of the limiting hole is less than the length of the limiting column. It can be understood that, in the process of returning from the terminal position to the starting position, the limiting column can be inserted into the limiting hole, and since the depth of the limiting hole is less than the length of the limiting column, when the limiting column abuts against the bottom of the limiting hole, there is still a gap between the connecting plate 51 and the shell 21, so as to avoid collision between the connecting plate 51 and the shell 21, and improve the safety performance.

[0063] In this embodiment, the diameter of the center needle body 3 gradually increases in the direction from the needle head to the needle tail of the center needle body 3. It can be understood that the needle head is tapered, which facilitates initial penetration into the rubber material 100, and as the center needle body 3 gradually penetrates, it is like a wedge inserted into the rubber material 100, which can make the center needle body 3 more firmly clamped into the rubber material 100, greatly enhancing the gripping force and anti-skid ability of the rubber material 100. And as the diameter of the center needle body 3 gradually increases, the insertion resistance and impact load can be reduced, the power requirement of the driving mechanism 53 is reduced, and the rubber material 100 is protected from damage.

[0064] Further, the end of the spiral blade 4 facing the rubber material 100 is provided with a cutting surface 41. In this way, the spiral blade 4 can be easily rotated into the rubber material 100.

[0065] In addition, the feeding head also includes a posture adjusting mechanism 8 which is connected with the mounting seat 1 to adjust the orientation of the center needle body 3. It can be understood that the posture adjusting mechanism 8 is electrically connected with the visual detection mechanism, and when the visual detection mechanism acquires the position information of the rubber material 100 or the position information of the feeding opening, it can not only transmit signals to the transplanting mechanism, but also transmit signals to the posture adjusting mechanism 8 to make the center needle body 3 face the rubber material 100 or the feeding opening.

[0066] Specifically, the posture adjusting mechanism 8 includes a first hollow rotary motor 81 and a second hollow rotary motor 82, the mounting seat 1 includes a first mounting plate 11 and a second mounting plate 12 which is vertically arranged with the first mounting plate 11, the rotating end of the first hollow rotary motor 81 is connected with the first mounting plate 11, and the first hollow rotary motor 81 can be connected with the transplanting end of the transplanting mechanism through the connecting column 9, the second hollow rotary motor 82 is arranged on the second mounting plate 12, and the rotating end of the second hollow rotary motor 82 is connected with the shell 21. Since the first mounting plate 11 and the second mounting plate 12 are vertically arranged, the rotating axis of the first hollow rotary motor 81 and the rotating axis of the second hollow rotary motor 82 are vertically arranged, so that the axis direction of the center needle body 3 can be adjusted under the action of the first hollow rotary motor 81 and the second hollow rotary motor 82, thereby adapting to different working conditions.

[0067] In the mixing process of the rubber compound 100, various additives such as reinforcing agents, fillers, softeners, vulcanizing agents, etc. need to be added to the mixer to ensure the mixing quality. At present, various additives are placed in the bag 200 together, and after the rubber compound 100 is put into the mixer, the bag 200 also needs to be put into the mixer.

[0068] Therefore, in the embodiment, the feeding head further comprises a second linear driving member 6 and a vacuum suction accessory 7. The second linear driving member 6 is arranged on the mounting seat 1 and is arranged side by side with the rotating mechanism 2. The vacuum suction accessory 7 is arranged on the driving end of the second linear driving member 6. The second linear driving member 6 is used to drive the vacuum suction accessory 7 to move to the lower side of the material limiting mechanism 5 to suck the bag 200. It can be understood that the vacuum suction accessory 7 can be moved to the lower side of the material limiting mechanism 5 under the action of the second linear driving member 6 to avoid interference with the material limiting mechanism 5. The vacuum suction accessory 7 can suck the bag 200 under the action of the transplanting mechanism, and then the feeding of the bag 200 can be completed under the action of the transplanting mechanism. Compared with manual feeding, the feeding efficiency can be further improved.

[0069] Exemplarily, the second linear driving member 6 is a linear cylinder in the prior art, and the vacuum suction accessory 7 comprises a vacuum suction plate and a plurality of suction nozzles arranged on the vacuum suction plate. The plurality of suction nozzles are in communication with a negative pressure source to realize the suction and fixation of the bag 200. Preferably, the bag 200 is made of a gas-impermeable material such as plastic.

[0070] In addition, to avoid interference between the suction nozzles and the connecting plate 51 when the bag 200 is sucked, the connecting plate 51 is provided with a cutout which is flush with the side surface of the housing 21 on which the second linear driving member 6 is arranged.

[0071] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application. It is unnecessary and impossible to enumerate all the implementation modes here. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
