Referring to fig. 1-3, a reclaiming assembly 100 according to an embodiment of a first aspect of the present application includes a reclaiming unit 110 and a first sensor 120. The first sensors 120 are provided in plurality, and each of the first sensors 120 is arranged along a straight line direction, the arrangement direction of the first sensors 120 is a first direction, and when the length direction of the pipe 200 is set along the first direction, and the pipe 200 is located within the detection range of the first sensors 120, the first sensors 120 can be triggered. The material taking unit 110 is used for picking up or putting down the pipe 200; when the first sensors 120 within the length range of the pipe 200 are all triggered by the pipe 200, the take-out unit 110 picks up the pipe 200; the take out unit 110 does not pick up the tubing 200 when the first sensor 120, which is within the length of the tubing 200, is not fully triggered by the tubing 200.

The material taking assembly 100 according to the embodiment of the application has at least the following advantages: when the length direction of the pipe 200 is coincident with the first direction (refer to fig. 2), that is, the placement timing of the pipe 200, the pipe 200 can trigger all the first sensors 120 within the length range of the pipe 200, and the material taking unit 110 can normally grasp the pipe 200 at this time; when the length direction of the pipe 200 does not coincide with the first direction (refer to fig. 3), even when the included angle α between the length direction of the pipe 200 and the first direction is larger, that is, the pipe 200 is not properly placed, the first sensors 120 arranged along the first direction will not be all triggered, and at this time, it is known that the pipe 200 is improperly placed, the material taking unit 110 does not grasp the pipe 200, and the probability that the improperly placed pipe 200 is picked up is lower.

Referring to fig. 1 to 3, in a modification of the above embodiment, a plurality of the reclaiming units 110 are provided, and each reclaiming unit 110 is arranged along the first direction; when the first sensors 120 within the length range of the pipe 200 are all triggered by the pipe 200, the corresponding take-out units 110 pick up the pipe 200; each pick-up unit 110 does not pick up a tubular 200 when the first sensor 120, which is within the length of the tubular 200, is not fully triggered by the tubular 200.

When the tube 200 is picked up by the picking units 110 aligned in the first direction (i.e., aligned in a row), if the tube 200 is not properly placed, a portion of the picking units 110 may not pick up the tube 200, and the falling risk of the tube 200 during the movement may be increased. In contrast, when the length direction of the pipe 200 does not coincide with the first straight direction (refer to fig. 3), even when the angle α between the length direction of the pipe 200 and the first straight direction is large, the first sensors 120 arranged along the first straight direction are not all triggered, and it is known that the pipe 200 is not properly placed, and the corresponding pick-up head 110 does not grasp the pipe 200. The improperly placed pipe 200 is not immediately fed, thereby being beneficial to reducing the falling risk of the pipe 200 in the moving process.

Referring to fig. 1, it should be noted that, since the lengths of the tubes 200 taken by the take out assembly 100 may be different, the number of first sensors 120 to be triggered may be different when the take out assembly 100 takes out the tubes 200, that is, a part of the first sensors 120 may be triggered, or all of the first sensors 120 may be triggered, and the number of first sensors 120 to be specifically triggered depends on the lengths of the tubes 200. Correspondingly, when the material taking assembly 100 takes the tubes 200 with different lengths, the number of the material taking units 110 may be different, that is, only a part of the material taking units 110 may be used, or all of the material taking units 110 may be used, and the number of the material taking units 110 specifically used depends on the length of the tubes 200.

Specifically, referring to fig. 1, the take-off assembly 100 is illustrated as it is gripping tubing 200 of different lengths. In fig. 1, the material taking unit 110 is provided with four, the first sensor 120 is also provided with four, and three kinds of pipes 200 of different lengths, namely, a first pipe 210, a second pipe 220, and a third pipe 230 are shown, wherein the length of the first pipe 210 is the largest, the length of the second pipe 220 is moderate, and the length of the third pipe 230 is the smallest.

When the material taking assembly 100 grabs the first pipe 210, the first pipe 210 can trigger all four first sensors 120, and all four material taking units 110 need to generate grabbing actions. When the material taking assembly 100 grabs the second pipe 220, the second pipe 220 can trigger the three first sensors 120 on the left side, and one first sensor 120 on the rightmost side is not triggered; correspondingly, the three material taking units 110 on the left side need to generate a grabbing action, and the material taking unit 110 on the rightmost side does not generate a grabbing action. When the material taking assembly 100 grabs the third pipe 230, the third pipe 230 can trigger the two first sensors 120 on the left side, and the two first sensors 120 on the right side are not triggered; correspondingly, the left two material taking units 110 need to generate grabbing actions, and the right two material taking units 110 do not generate grabbing actions.

Specifically, the distinction between the pick-up assembly 100 picking an aligned first tube 210 and picking a skewed first tube 210 is illustrated. Referring to fig. 2, when the length direction of the first pipe 210 coincides with the first direction, since each of the first sensors 120 is also aligned along the first direction, all four first sensors 120 can be triggered, and this indicates that the first pipe 210 is aligned. When the included angle α between the length direction of the first pipe 210 and the first direction is larger, the two first sensors 120 on the right side are not triggered by the first pipe 210, so that it can be determined that the first pipe 210 is not aligned.

Specifically, the number of the material taking units 110 may be one, two, three, four (refer to fig. 1), or other numbers, which are determined according to the maximum length of the tube 200 required to be taken by the material taking assembly 100. The number of first sensors 120 may be two, three, four (see fig. 1), or other numbers, and the minimum distance between two adjacent first sensors 120 is determined by the minimum length of tubing 200 required to be obtained by the take-out assembly 100, and the distance between the two farthest first sensors 120 is determined by the maximum length of tubing 200 required to be obtained by the take-out assembly 100.

It should be noted that some of the first sensors 120 are not triggered, which may be that the length of the pipe 200 is smaller or that the pipe 200 is skewed. At this time, it is necessary to determine how many first sensors 120 are to be activated in advance according to the length of the pipe, and even directly determine which positions of the first sensors 120 are to be activated. When the first sensors 120 that should be triggered are not triggered, or the number of first sensors 120 that are triggered is less than a set value (see description below), it is known that the pipe 200 is not properly placed.

It should be noted that the grabbing is only one action of the taking unit 110 to take the pipe 200, and does not mean that the taking unit 110 must be a clamping jaw, and the taking unit 110 may be other devices (see description below) that can take the pipe 200.

It should be noted that, when the first sensors 120 within the length range of the pipe 200 are triggered by the pipe 200, the corresponding material taking units 110 grab the pipe 200, where "corresponding material taking units 110" refers to material taking units 110 within the length range of the pipe 200. However, when the pipe 200 is light, the gripping action is not necessarily generated by all of the material taking units 110 within the length range of the pipe 200, but may be generated by some of the material taking units within the length range of the pipe 200.

Referring to fig. 1, in the modification of the above embodiment, the number of the reclaiming units 110 and the first sensors 120 is equal for any one reclaiming unit 110: when one of the first sensors 120 closest to the take-out unit 110 is not triggered, the take-out unit 110 does not grasp the tubing 200; the pick-up unit 110 grabs the tubing 200 when one of the first sensors 120 closest to the pick-up unit 110 is activated.

Thus, each of the reclaiming units 110 is individually controlled by one of the first sensors 120, and the corresponding reclaiming unit 110 may be deactivated when the first sensor 120 is not activated, thereby contributing to energy conservation.

Specifically, the length of a portion of the tubing 200 may not be sufficient to trigger all of the first sensors 120, at which time there are a plurality of possibilities for the location of the tubing 200 in the first direction even if the length direction of the tubing 200 is set in the first direction. At this time, as long as the number of the first sensors 120 that are triggered satisfies the set value, the on-utilization reclaiming unit 110 may normally operate, and the off-utilization reclaiming unit 110 may not operate, thereby saving energy.

For example, referring to fig. 1, the second pipe 220 located above is located to the left, only the three first sensors 120 on the left are activated, and the one first sensor 120 on the rightmost side is not activated; correspondingly, the three material taking units 110 on the left side generate a grabbing action, and the material taking unit 110 on the rightmost side does not generate a grabbing action. The second pipe 220 below is located at a right position, and only the three first sensors 120 on the right side are triggered, and the first sensor 120 on the leftmost side is not triggered; correspondingly, the three material taking units 110 on the right side generate a grabbing action, and the material taking unit 110 on the leftmost side does not generate a grabbing action. At this time, even though there are two positions of the second tube 220 along the first direction, the material taking units 110 can all take the second tube 220 by three material taking units 110 without the four material taking units 110 all generating the grabbing action, thereby saving energy.

Referring to fig. 4, according to some embodiments of the present application, the number of first sensors 120 is twice the number of reclaiming units 110, and two first sensors 120 are disposed between two adjacent reclaiming units 110, for any one reclaiming unit 110: when neither of the two first sensors 120 closest to the pick-up unit 110 is triggered, the pick-up unit 110 does not grasp the tubing 200; the pick-up unit 110 grips the tubing 200 when at least one of the two first sensors 120 closest to the pick-up unit 110 is activated.

In actual production, the length of the portion of tubing 200 may be relatively close to the distance between the two take-off units 110. At this time, if the position of the tube 200 along the first direction is improperly placed, the material taking unit 110 near the edge of the tube 200 in the length direction can actually take the tube 200 to provide a force for lifting the tube 200, but since only one side of the material taking unit 110 is provided with the first sensor 120, if the first sensor 120 is not triggered, the tube 200 which originally meets the grabbing condition may be caused, and the tube 200 is determined to not meet the grabbing condition (for example, the number of the material taking units 110 which generate the grabbing action is insufficient), and the normal handling of the tube 200 is easily affected.

Specifically, with reference to fig. 4 and 5, an example is described. The number of the first sensors 120 of the material taking assembly 100 in fig. 4 is twice the number of the material taking units 110, and the number of the first sensors 120 of the material taking assembly 100 in fig. 5 is equal to the number of the material taking units 110, and the second pipe 220 is gripped.

Referring to fig. 5, in the initial setting, as long as three first sensors 120 are triggered, the second pipe 220 can be grabbed and lifted by three material taking units 110 to complete feeding or discharging. However, due to the length and placement position of the second tube 220, the third first sensor 120 from left to right cannot be triggered by the right end of the second tube 220, so that only the two first sensors 120 on the left side are triggered, and as a result, it is determined that the second tube 220 cannot be gripped, and in fact, the second tube 220 satisfies the gripping condition.

Referring to fig. 4, at this time, the first sensors 120 are disposed on both sides of any one of the material taking units 110, and even if the first sensor 120 on the right side of the third material taking unit 110 from left to right is not triggered, the first sensor 120 on the left side of the material taking unit 110 is still triggered, the material taking unit 110 can still work normally, and the second pipe 220 can be grasped normally.

It should be noted that, in fig. 4, the condition of the second pipe 220 being grabbed is changed to that when five or six first sensors 120 are triggered, the second pipe 220 may be grabbed and lifted by three material taking units 110.

In summary, for any one of the material taking units 110, the first sensors 120 dedicated to controlling the material taking unit 110 are disposed on two sides of the material taking unit 110, no matter which first sensor 120 is triggered on the edge of the tube 200 along the length direction, the material taking unit 110 can generate a grabbing action, so that the probability that the material taking unit 110 generating the grabbing action does not generate the grabbing action can be reduced, the material taking assembly 100 can normally carry the tube 200 under certain specific conditions, and the adaptability of the material taking assembly 100 is stronger.

Referring to fig. 5, in a modification of the above embodiment, adjacent first sensors120 and a minimum distance d between the take-off unit 110 ₁ Is 5-100 mm.

Because the first sensor 120 and the material taking unit 110 are close together, the first sensor 120 can provide a more accurate reference for whether the corresponding material taking unit 110 generates the grabbing action after detecting whether the pipe exists below. Meanwhile, in order to avoid collision between the first sensor 120 and the material taking unit 110, the first sensor 120 and the material taking unit 110 should be kept at a corresponding distance. Minimum distance d between adjacent first sensor 120 and take-off unit 110 ₁ The range of values is 5-100 mm, which can satisfy both requirements, the first sensor 120 is not too far from the pick-up unit 110, and the first sensor 120 does not collide with the pick-up unit 110.

Specifically, the minimum distance d between adjacent one of the first sensors 120 and one of the take-off units 110 ₁ 5mm, 10mm, 50mm, 80mm, 100mm or other values, with 50mm being preferred.

In a modification of the above embodiment, the first sensor 120 includes at least one of a proximity switch, an ultrasonic ranging sensor, and an electro-optical ranging sensor.

The proximity switch, the ultrasonic ranging sensor and the electro-optical ranging sensor can feed back the position of the pipe 200, thereby providing a reference for the grabbing action of the material taking unit 110.

It should be noted that, when the first sensor 120 includes a proximity switch, the proximity switch may need to be triggered after touching the pipe 200, and the ultrasonic ranging sensor and the electro-optical ranging sensor may both be triggered in the process that the material taking unit 110 is approaching the pipe 200 downward, so that the triggering time of the ultrasonic ranging sensor and the electro-optical ranging sensor is earlier.

In a modification of the above embodiment, the take-out unit 110 includes an electromagnet, suction cup, or clamping jaw. The electromagnet, suction cup or clamping jaw can grasp or release the pipe 200 to transfer the pipe 200.

It should be noted that, the power supply or the power failure of the electromagnet, the vacuumizing or the vacuum breaking of the sucker, and the folding or opening of the clamping jaw are controlled by a controller (such as a PLC, a singlechip, etc.), and the controller receives the electric signals fed back by the proximity switch, the ultrasonic ranging sensor or the photoelectric ranging sensor and then sends corresponding control signals to the electromagnet, the sucker or the clamping jaw, thereby controlling the actions of the electromagnet, the sucker or the clamping jaw.

Referring to fig. 5, in some embodiments of the present application, the take out assembly 100 further includes a first cross member 140 and a frame 150. The first cross member 140 is detachably fixed to the frame 150, and each first sensor 120 and each material taking unit 110 are mounted on the first cross member 140, and a length direction of the first cross member 140 is a first direction.

Therefore, when the length of the pipe 200 to be obtained is greatly changed, the first cross beam can be replaced, so that the number and the position of the first sensors 120 and the number and the position of the material taking units 110 can be adaptively adjusted, the compatibility of the material taking assembly 100 can be improved, and the equipment cost can be reduced.

Specifically, the first cross member 140 is generally fixed to the frame 150 by a fastener such as a screw or a bolt, thereby achieving the detachable connection.

Further, when the frame 150 is to be mounted with the guide rail having a length direction disposed in a vertical direction, the frame 150 itself may be disposed in a vertical direction, while the first cross member 140 is generally disposed in a horizontal direction in a length direction. At this time, the first beam 140 and the frame 150 are disassembled, so that the transportation space can be saved and the transportation is convenient.

Referring to fig. 6 and 7, in fig. 7, the second pulley 317 and the second gear 324 are shown for clarity, and some parts are omitted. The handling device according to the second aspect of the embodiments of the present application includes a take out assembly 100 and a drive member 300. The driving part 300 is used for driving the material taking assembly 100 to move in the up-down direction, and the driving part 300 is also used for driving the material taking assembly 100 to move in the horizontal direction.

According to the carrying device disclosed by the embodiment of the application, the carrying device has at least the following beneficial effects: by using the material taking assembly 100, the risk of dropping the pipe 200 is reduced, and the safety performance of the handling device is higher.

The movement of the material taking assembly 100 in the horizontal direction refers to a movement in any straight line direction on the horizontal plane, for example, a movement in the front-back direction, or a movement in the left-right direction.

Specifically, the handling device further includes a gantry 400, and the driving part 300 includes a first driving assembly 310, a second driving assembly 320, and a second beam 330. The first driving assembly 310 includes a first shaft 311, a first motor 312, a first gear 313, a first rack 314, a first rail 315, a first pulley 316, and a second pulley 317. The two first racks 314 are provided, the length directions of the two first racks 314 are all along the vertical direction, and the two first racks 314 are fixed on the frame body 150 through fasteners such as screws. The first gears 313 are also provided in two, and the two first gears 313 are respectively engaged with the two first racks 314. The first rotating shafts 311 are also provided in two, and the two first rotating shafts 311 are coaxially provided. One end of the two first rotating shafts 311, which are close to each other, is in transmission connection with the output shaft of the first motor 312 through a speed reducer, and one end of the two first rotating shafts 311, which are far away from each other, is respectively fixed with a first gear 313.
