Description

Technical Field

[0001] The invention relates to a machine for preforming a rubber crawler track, in particular to an automatic feeding device for a rubber crawler track core metal and a rubber crawler track preforming production line. Background Art

[0002] Rubber tracks are walking parts with large contact surface with the ground. They have the advantages of anti-skid and anti-sinking, and are widely used in engineering machinery, agricultural machinery and military equipment. Conventional rubber tracks are mainly composed of three parts: the belt body, the core metal inside the belt body and the strong layer; among them, the core metal acts as a supporting skeleton, directly meshing with the driving wheel of the mechanical equipment, playing the role of transmitting power and supporting the mechanical equipment.

[0003] In the production process of rubber tracks, it is necessary to produce the track blanks on the preforming production line, and then vulcanize and mold them to obtain the finished rubber tracks. During the preforming process, the core gold needs to be arranged on the material table according to the rule that the iron teeth are facing downward, waiting for the robot to grab it and send it to the preforming equipment (the preforming equipment can refer to the Chinese patent document CN 114434843A). At present, due to the lack of automated feeding equipment, the core gold is arranged on the material table one by one manually, which has a high labor intensity and high labor costs. In addition, the preforming equipment is often short of materials due to untimely feeding of the iron teeth, which affects production efficiency. Therefore, it is necessary to develop a device that can automatically feed the core gold instead of manual labor. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present application provides an automatic feeding device for rubber track core gold. The automatic feeding device for rubber track core gold of the present application adopts a specific design, which can automatically replace manual feeding operations for rubber track core gold in the rubber track preforming production line, thereby reducing labor costs; and the assembly line-style feeding avoids the problem of material shortage in the preforming equipment due to untimely feeding of iron teeth, thereby improving the production efficiency of rubber tracks. In addition, the present application also provides a rubber track preforming production line using the automatic feeding device for rubber track core gold.

[0005] For the feeding equipment, the technical solution of this application is:

[0006] The automatic feeding equipment for rubber track core metal comprises a feeding and tidying device, an arrangement detection device, a flip transfer device and a control system; the feeding and tidying device comprises a silo; a belt conveyor A is provided at the bottom of the silo, and correspondingly, a stepped lifting assembly is provided on the front side of the silo; the stepped lifting assembly comprises a group of fixed plates inclined forward and arranged in a stepped manner, and a lifting and lowering push plate is provided between two adjacent fixed plates; when the push plate is at the lowest point, the top of the push plate is lower than the top of the fixed plate behind it; when the push plate is at the highest point, the top of the push plate is higher than the top of the fixed plate in front of it; the front end of the A belt conveyor is connected with the top of the fixed plate located at the bottom; the arrangement detection device comprises a B belt conveyor; the conveying route of the B belt conveyor is divided into a receiving section, a detection section and a feeding section ; In the material receiving section, one side of the B belt conveyor is connected to the fixed plate located at the top, and the other side is provided with an A material baffle plate; in the detection section, one side of the B belt conveyor is provided with a sensor assembly and a kicking mechanism, and the other side is provided with a return material chute; during operation, if the sensor assembly detects that the iron teeth of the core gold are not facing correctly or there are multiple core golds stacked, the kicking mechanism will push the corresponding core gold into the return material chute; the flipping and transfer device is arranged at the end of the B belt conveyor; the flipping and transfer device includes a transfer table, a flipping assembly and a transfer assembly; the transfer table is used to receive the core gold from the B belt conveyor; a position sensor is provided on the transfer table, and when working, when the position sensor detects the core gold, the flipping assembly flips the core gold on the transfer table 180°, and then the transfer assembly transfers the flipped core gold to the swing table.

[0007] Compared with the prior art, the automatic feeding equipment for rubber track core metal of the present application can automatically feed on the rubber track preforming production line by setting a feeding and tidying device, an arrangement detection device and a flip transfer device that work together. The core metal is placed on the discharge table with the iron teeth facing downwards, which can reduce labor costs and avoid the problem of shortage of materials on the discharge table due to untimely feeding, thereby improving the production efficiency of the rubber track preforming production line. Specifically, the feeding and tidying device is composed of a silo, a belt conveyor A and a stepped lifting assembly. When working, the belt conveyor A conveys the core metal to the stepped lifting assembly, and the stepped lifting assembly lifts the core metal upwards one level at a time. Due to the special structure of the core metal itself, if the core metal is not in a state with the iron teeth facing upwards during the lifting process, it is easy to fall due to instability. Therefore, after multiple levels of lifting, the core metal that finally reaches the arrangement detection device is basically in a state with the iron teeth facing upwards; the arrangement detection device is composed of a belt conveyor B, a sensor assembly and When the core metal passes through the detection section, during operation, if the sensor component detects that the iron teeth of the core metal are not facing the correct direction or there are multiple core metals stacked, the kicking mechanism will remove the corresponding core metal to avoid affecting the subsequent loading process; the flipping and transferring device includes a transfer table, a flipping component and a transfer component. After the transfer table receives the core metal from the B belt conveyor, the flipping component flips the core metal 180 degrees so that the iron teeth face downward, and then the transfer component transfers the flipped core metal to the swing table of the rubber track preforming production line to complete the automatic loading of the core metal.

[0008] As an optimization, in the aforementioned rubber crawler core gold automatic feeding equipment, a C-belt conveyor is provided at the end of the return slideway; the end of the C-belt conveyor is connected to the return port on the side of the silo to return the core gold to the silo. Thus, the core gold rejected by the kicking mechanism can be returned to the silo, further improving the level of automation.

[0009] As an optimization, in the aforementioned automatic feeding equipment for core metal of rubber tracks, a feeding device is provided at the rear side of the feeding and regularizing device; the feeding device includes a tipping bucket and a tipping bucket driving assembly; a detachable material box is provided on the tipping bucket; the tipping bucket can be driven by the tipping bucket driving assembly to flip over and pour the core metal in the material box into the silo. Thus, after the core metal is produced, it is collected in a material box and then transferred to the preforming workshop and loaded onto the tipping bucket. When the silo is short of material, the tipping bucket driving assembly is controlled to work to replenish the silo, which helps to reduce labor intensity.

[0010] Furthermore, in the aforementioned rubber track core metal automatic feeding equipment, a gravity sensor is provided at the bottom of the silo, and when the gravity sensor detects that there is a lack of material in the silo, the control system controls the bucket driving assembly to work and replenish the material, thereby further improving the degree of automation.

[0011] As an optimization, in the aforementioned automatic feeding equipment for core gold of rubber tracks, the sensor assembly includes a core gold detection sensor and an iron tooth detection sensor, which are arranged one above the other; when working, if the core gold detection sensor continuously detects the core gold within a set time interval, and the iron tooth detection sensor detects the core gold twice within the time interval, the control system determines that the orientation of the core gold is correct and there is no overlap, otherwise, the control system controls the kicking mechanism to remove the core gold detected by the core gold detection sensor. This detection method is consistent with the structural characteristics of the core gold, has high reliability, and is easy to implement.

[0012] As an optimization, in the aforementioned rubber crawler core metal automatic feeding equipment, B baffle plates are provided on both sides of the B belt conveyor in the feeding section. With this structure, the core metal can be limited before entering the flip transfer device, which has a corrective effect on some skewed core metals, ensuring that the core metal maintains a consistent posture when entering the flip transfer device, thereby improving the reliability of the equipment.

[0013] As an optimization, in the aforementioned rubber track core gold automatic feeding equipment, the A baffle plate and the B baffle plate are both provided with guide rods in groups. With this structure, the friction between the core gold and the A baffle plate and the B baffle plate can be reduced, making it easier for the B belt conveyor to transport the core gold.

[0014] As an optimization, in the aforementioned rubber track core metal automatic feeding equipment, the flip assembly includes A telescopic cylinder, A rotating cylinder and A pneumatic clamp; the A telescopic cylinder is connected to the A rotating cylinder, used to drive the A rotating cylinder to move forward and backward; the A rotating cylinder is connected to the A pneumatic clamp, used to drive the A pneumatic clamp to rotate; the A pneumatic clamp is used to clamp the core metal. The flip assembly adopts the above structural design, which can not only meet the use requirements, but also has the advantages of easy implementation and low cost.

[0015] As an optimization, in the aforementioned automatic feeding equipment for core metal of rubber crawler, the transfer assembly includes a B telescopic cylinder, a B rotary cylinder, a connecting rod and a B pneumatic clamp; the B telescopic cylinder is connected to the B rotary cylinder to drive the B rotary cylinder to move up and down; the B rotary cylinder is connected to the B pneumatic clamp through the connecting rod; the B pneumatic clamp is used to clamp the core metal. The moving assembly adopts the above structural design, which can not only meet the use requirements, but also has the advantages of easy implementation and low cost.

DETAILED DESCRIPTION

[0034] The present application is further described below in conjunction with the accompanying drawings and embodiments, but is not intended to be limiting of the present application. In the following embodiments, the contents not described in detail or not shown in detail in the accompanying drawings are all common technical knowledge in the art.

[0035] Example (see Figure 1 to Figure 14 ):

[0036] In this embodiment, the rubber track preforming production line has a material swinging table 8 (the material swinging table 8 is a prior art), and a rubber track core gold automatic feeding device is provided on the side of the material swinging table 8. The rubber track core gold automatic feeding device includes a feeding regularization device 1, an arrangement detection device 2, a flip transfer device 3 and a control system. When working, the rubber track core gold automatic feeding device places the core gold 4 on the material swinging table 8 according to the rule that the iron teeth face downward.

[0037] In this embodiment, the material loading and sorting device 1 includes a silo 11; a belt conveyor A 12 is provided at the bottom of the silo 11, and correspondingly, a stepped lifting assembly 13 is provided on the front side of the silo 11; the stepped lifting assembly 13 includes a group of fixed plates 131 inclined forward and arranged in a stepped manner, and a push plate 132 that can be raised and lowered is provided between two adjacent fixed plates 131; when the push plate 132 is at the lowest point, the top of the push plate 132 is lower than the top of the fixed plate 131 behind it; when the push plate 132 is at the highest point, the top of the push plate 132 is higher than the top of the fixed plate 131 in front of it; the front end of the belt conveyor A 12 is connected to the top of the fixed plate 131 located at the bottom. When working, the belt conveyor 12 conveys the core gold 4 in the silo 11 to the stepped lifting assembly 13, and the push plate 132 reciprocates under the drive of the cylinder to lift the core gold 4 up step by step until it reaches the arrangement detection device 2. During the lifting process, if the iron teeth 41 of the core gold 4 are not in an upward state or there are multiple core golds 4, the core gold 4 will fall back into the silo 11 due to instability. Thereby ensuring that the core gold 4 entering the arrangement detection device 2 is basically in a state where the iron teeth 41 are facing upward, and basically no stacking occurs.

[0038] In this embodiment, the arrangement detection device 2 includes a B belt conveyor 21; the conveying route of the B belt conveyor 21 is divided into a receiving section, a detection section and a feeding section; at the receiving section, one side of the B belt conveyor 21 is connected to the fixed plate 131 located at the top, and the other side is provided with an A material blocking plate 211; at the detection section, one side of the B belt conveyor 21 is provided with a sensor assembly 22 and a kicking mechanism 23, and the other side is correspondingly provided with a return material chute 24; when working, if the sensor assembly 22 detects that the iron teeth 41 of the core gold 4 are not facing upward or there are multiple core golds 4 stacked, the kicking mechanism 23 pushes the corresponding core gold 4 into the return material chute 24. When working, the B belt conveyor 21 conveys the core gold 4 to the feeding section. When the core gold 4 passes through the detection section, the sensor assembly 22 detects it. If the iron teeth 41 of the core gold 4 are not facing upward or there are multiple core golds 4 stacked, the control system controls the kicking mechanism 23 to work and remove it.

[0039] In this embodiment, the flip transfer device 3 is arranged at the end of the B belt conveyor 21; the flip transfer device 3 includes a transfer table 31, a flip assembly 32 and a transfer assembly 33; the transfer table 31 is used to receive the core gold 4 from the B belt conveyor 21; the transfer table 31 is provided with a position sensor 34 (in the embodiment, the position sensor 34 adopts a contact sensor, when the core gold 4 contacts the sensor contact, the position sensor 34 detects the core gold 4), when working, when the position sensor 34 detects the core gold 4, the flip assembly 32 flips the core gold 4 on the transfer table 31 by 180°, and then the transfer assembly 33 transfers the flipped core gold 4 to the swing table 8. As a result, the core gold 4 placed on the swing table 8 is in a state where the iron teeth 41 are facing downward.

[0040] In this embodiment, a C-belt conveyor 5 is provided at the end of the return chute 24; the end of the C-belt conveyor 5 is connected to the return port on the side of the silo 11, and is used to return the core gold 4 to the silo 11. With this structure, the core gold 4 rejected by the kicking mechanism 23 can be returned to the silo 11, further improving the level of automation.

[0041] In this embodiment, a feeding device 6 is provided at the rear side of the feeding and tidying device 1; the feeding device 6 comprises a tipping bucket 61 and a tipping bucket driving assembly 62; a detachable material box 7 is provided on the tipping bucket 61; the tipping bucket 61 can be driven by the tipping bucket driving assembly 62 to realize flipping (as shown in the attached Figure 2 As shown in FIG. 1 , the core gold 4 in the material box 7 is poured into the silo 11. With this structure, after the core gold 4 is produced, it is collected by the material box 7 and then transferred to the preforming workshop and loaded onto the tipping bucket 61. When the silo 11 is short of material, the tipping bucket driving assembly 62 is controlled to work, so that the silo 11 can be replenished, which is conducive to further reducing labor intensity.

[0042] In this embodiment, a gravity sensor is provided at the bottom of the silo 11. When the gravity sensor detects that there is a lack of material in the silo 11 (in the embodiment, when the gravity sensor detects that the weight is less than 100KG, the control system determines that there is a lack of material in the silo 11), the control system controls the bucket driving assembly 62 to work and replenish the material. Thus, the degree of automation is further improved.

[0043] In this embodiment, the sensor assembly 22 includes a core gold detection sensor 221 and an iron tooth detection sensor 222 which are arranged one above the other (in the embodiment, the core gold detection sensor 221 and the iron tooth detection sensor 222 use photoelectric proximity switches); when working, if the core gold detection sensor 221 continuously detects the core gold 4 within 3 seconds, and the iron tooth detection sensor 222 detects the core gold 4 twice within this time period (detects two upward iron teeth 41), the control system determines that the orientation of the core gold 4 is correct and there is no overlap (if there is overlap, the core gold detection sensor 221 will continuously detect the core gold 4 for more than 3 seconds), otherwise, the control system controls the kicking mechanism 23 to remove the core gold detected by the core gold detection sensor 221. This detection method is consistent with the structural characteristics of the core gold 4, has high reliability, and is easy to implement.

[0044] In this embodiment, on the feeding section, B baffle plates 212 are provided on both sides of the B belt conveyor 21. With this structure, the core metal 4 can be limited before entering the flip transfer device 3, which has a corrective effect on the partially deflected core metal 4, ensuring that the core metal 4 maintains a consistent posture when entering the flip transfer device 3, thereby improving the reliability of the equipment.

[0045] In this embodiment, the A baffle plate 211 and the B baffle plate 212 are both provided with guide rollers 213. With this structure, the friction between the core gold 4 and the A baffle plate 211 and the B baffle plate 212 can be reduced, so that the B belt conveyor 21 can convey the core gold 4.

[0046] In this embodiment, the flipping assembly 32 includes an A telescopic cylinder 321, an A rotating cylinder 322 and an A pneumatic clamp 323; the A telescopic cylinder 321 is connected to the A rotating cylinder 322 to drive the A rotating cylinder 322 to move forward and backward; the A rotating cylinder 322 is connected to the A pneumatic clamp 323 to drive the A pneumatic clamp 323 to rotate; the A pneumatic clamp 323 is used to clamp the core gold 4; the transfer assembly 33 includes a B telescopic cylinder 331, a B rotating cylinder 332, a connecting rod 333 and a B pneumatic clamp 334; the B telescopic cylinder 331 is connected to the B rotating cylinder 332 to drive the B rotating cylinder 332 to move up and down; the B rotating cylinder 332 is connected to the B pneumatic clamp 334 through the connecting rod 333; the B pneumatic clamp 334 is used to clamp the core gold 4. The flip assembly 32 and the moving assembly 33 adopt the above-mentioned structural design, which can not only meet the use requirements, but also have the advantages of easy implementation and low cost.

[0047] In this embodiment, the steps of automatically feeding the core metal in the rubber track preforming production line are as follows:

[0048] ①: Place the material box 7 containing the core gold 4 on the tipping bucket 61;

[0049] ②: When the weight detected by the gravity sensor is less than the set value, the control system controls the tipping bucket 61 to work and pour the core gold 4 in the material box 7 into the silo 11;

[0050] ③: The A belt conveyor 12 conveys the core gold 4 thereon toward the step-type lifting assembly 13; the step-type lifting assembly 13 lifts the core gold 4 step by step and conveys it to the B belt conveyor 21 in the arrangement detection device 2;

[0051] ④: After receiving the core gold 4, the receiving section of the belt conveyor 21 of B conveys the core gold 4 thereon toward the turning transfer device 3;

[0052] ⑤: When the core gold 4 on the B belt conveyor 21 passes through the detection section, the core gold detection sensor 221 and the iron tooth detection sensor 222 will detect the core gold 4. When it is detected that the iron teeth 41 of the core gold 4 are not facing correctly or there are multiple core golds 4 stacked, the kicking mechanism 23 is started to push the corresponding core gold 4 into the return chute 24 and transport it back to the silo 11 through the C belt conveyor 5;

[0053] ⑥: The qualified core gold 4 is transported by the B belt conveyor 21 to the transfer table 31 of the flip transfer device 3;

[0054] ⑦: When the position sensor 34 on the turntable 31 detects the core gold 4, the A telescopic cylinder 321 of the flip assembly 32 extends, driving the A rotating cylinder 322 and the A pneumatic clamp 323 to move toward the core gold 4. After moving into position, the A pneumatic clamp 323 clamps the core gold 4, the A telescopic cylinder 321 retracts, the A rotating cylinder 322 drives the A pneumatic clamp to rotate 180°, and the A telescopic cylinder 321 extends again. After extending into position, the A pneumatic clamp 323 releases the core gold 4 and puts the core gold 4 back on the turntable 31, and the A telescopic cylinder 321 retracts again to return to position (to avoid interference with the transfer assembly 33);

[0055] ⑧: The B telescopic cylinder 331 of the transfer assembly 33 retracts, driving the B rotating cylinder 332, the connecting rod 333 and the B pneumatic clamp 334 to descend and move toward the flipped core metal 4. After moving into position, the B pneumatic clamp 334 clamps the core metal 4, the B telescopic cylinder 331 extends (to raise the core metal 4 to avoid interference), the B rotating cylinder 332 drives the B pneumatic clamp 334 to rotate 90°, the B telescopic cylinder 331 retracts again, and after being in position, the B pneumatic clamp 334 releases the core metal 4 and places the core metal 4 on the material placing table 8, the B telescopic cylinder 331 extends again, and the B rotating cylinder 332 drives the B pneumatic clamp 334 to rotate 90° in the opposite direction to reset;

[0056] ⑨: Repeat the above steps to carry out the automatic batch loading operation of core gold 4.
