Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and specifically to a box-feeding machine. Background Technology

[0002] A robotic arm for gripping and transferring workpieces includes a moving mechanism, a gripping mechanism, and a detection component. The moving mechanism drives the gripping mechanism to move horizontally and move vertically. The gripping mechanism includes two clamping members arranged opposite each other. The gripping mechanism can move the two clamping members closer or further apart, thereby clamping or releasing the workpiece. The detection component includes a magnetic scale, a laser rangefinder, and a CCD camera, which can detect the distance between the two clamping members and the clamping condition between the two clamping members.

[0003] The current process involves feeding tape boxes. Multiple tape boxes are initially placed horizontally in a standing position in multiple rows within a material box and fed to the feeding machine. In the subsequent processing steps, the tape boxes need to be placed in a lying position at the feeding station. Therefore, the feeding process requires removing the tape boxes from the material box and changing them from a standing to a lying position. Furthermore, since different orders have different quantities of tape boxes, not every material box is filled completely, and there may be variations in the number of tape boxes in different rows within the material box.

[0004] In this situation, firstly, multiple tape boxes in a row are too close together to be easily removed individually; even if one tape box is removed, adjacent tape boxes will tip over due to the empty space left by the removed box. Secondly, tape boxes not in a row will also tip over because at least one side will not be supported by the material box. Thirdly, if the entire row of tape boxes is removed and reversed to be stacked vertically, the total number and length of tape boxes in each row will differ, and the height of the top tape box in each vertically stacked row will also differ, making it impossible to standardize the loading and unloading height. These problems make it difficult to automate tape box loading. Summary of the Invention

[0005] The purpose of this invention is to provide a carton feeding machine that enables automated feeding of cartons.

[0006] The present invention provides a box-loading machine comprising a first moving mechanism and a gripping mechanism. The first moving mechanism drives the gripping mechanism to move horizontally and move vertically. The gripping mechanism includes two clamping members arranged opposite each other, which can be moved closer or further apart by the gripping mechanism. It includes a carrier and a side stop. The carrier includes two partitions and a box-loading space formed between the two partitions. The side stop has mating parts on both sides. The side stop is placed in the box-loading space, and each of the two mating parts abuts against a partition. A first clamping clearance opening is formed between the two mating parts, allowing the clamping members to enter. It also includes a first driving unit, a second driving unit, a rotating chamber, and a movable stop. The rotating chamber can be rotated under the drive of the first driving unit. The rotating chamber has an entrance opened along its first direction and an exit opened along its second direction. The movable stop is movably disposed in the rotating chamber along the second direction and is driven to move by the second driving unit. The movable stop has a third clamping clearance opening allowing the clamping members to enter.

[0007] As can be seen from the above solution, by setting a side stop that can be locked in the tape box placement space and has a first clamping clearance opening, when a row of tape boxes is not full, the side stop can be used to block the row of tape boxes to prevent them from tipping over, without affecting the clamping member's ability to clamp and remove the entire row of tape boxes from the side of the row direction. Furthermore, the invention also includes a rotating chamber, which not only changes multiple horizontally arranged and standing tape boxes to vertically stacked and flat, but also determines the target stroke of the movable stop based on the detection data obtained during the gripping mechanism's gripping, ensuring that the top tape box is at a uniform height each time, facilitating subsequent loading and unloading. Therefore, the invention solves the problems of tape box posture conversion, tape box tipping, and inconsistent unloading height, achieving automated tape box loading.

[0008] A further option is to provide a cover that can block at least part of the entrance and a third drive unit that drives the cover to move.

[0009] As can be seen from the above, the inlet needs to be large enough to accommodate a full row of tape boxes. Even with restrictions in other directions when the rotating chamber is upright, tape boxes may still fall out of the inlet. To address this, the present invention also includes a cover that can block the inlet. The inlet opens when the rotating chamber is horizontal and tape boxes are being loaded, and after loading is complete, it blocks at least a portion of the inlet, effectively preventing tape boxes from falling out and also providing a certain positioning effect.

[0010] A further option is to have the cover be a flip cover with the rotation axis along the second direction.

[0011] As can be seen from the above, this setting occupies less space during the opening and closing of the lower cover, which is conducive to the compact layout of the feeding machine and reduces the space occupied.

[0012] A further proposed solution includes a rack and a gear; the third drive unit drives the rack to move in a straight line, and the gear is coaxially connected to the flip cover, with the rack meshing with the gear.

[0013] As can be seen from the above, under this configuration, the third drive unit can be a cylinder, which helps to reduce equipment costs.

[0014] A further embodiment is that the rotating chamber includes a first side portion, the first side portion having an elongated hole extending along a second direction, and a transmission assembly being disposed on the outer side of the first side portion; a second drive unit is disposed outside the rotating chamber, and the second drive unit, the transmission assembly, and the movable stop are sequentially connected in a transmission manner, a part of the movable stop being connected to the transmission assembly on the outer side of the first side portion, and the other part of the movable stop extending into the rotating chamber through the elongated hole.

[0015] As can be seen from the above, this setting minimizes the space occupied in the warehouse and avoids affecting the placement of the boxes.

[0016] A further option is that the rotating chamber includes a second side in its own third direction, and the rotating chamber is equipped with a clamping mechanism, which is opposite to the second side in the third direction inside the rotating chamber.

[0017] A further proposed solution is to position the clamping mechanism closer to the outlet in the second direction.

[0018] As can be seen from the above, under this configuration, when the rotating chamber is horizontal and the tape cassette has been loaded, the clamping mechanism presses down the first tape cassette closest to the outlet. This prevents the first tape cassette from falling out of the outlet, and at this time, the first tape cassette acts as a barrier for the other tape cassettes, preventing them from falling out of the outlet as well. Furthermore, the clamping mechanism is located near the outlet, bringing the highest tape cassette closer to the outlet, making it easier for the suction mechanism to pick up the parts.

[0019] Another further option is that the side stop includes a first elastic arm, a cross arm, and a second elastic arm that are bent and extended in sequence. The elastic arms are mating parts, and a first clamping clearance is formed between the two elastic arms and the cross arm.

[0020] As can be seen from the above, the side guards can be made of one-piece plastic molding or metal sheet bending molding to meet the elastic deformation requirements. Furthermore, since each vehicle needs to have side guards, this configuration facilitates the batch processing of side guards, and the processing is simple and the cost is low.

[0021] Another further option is that, along the length of the box placement space, the fourth side of the carrier is provided with two support parts facing the box placement space, and a second clamping clearance opening for accommodating another clamping member is formed between the two support parts.

[0022] As can be seen from the above, under this configuration, only one side stop and the fourth side of the carrier are needed to position a row of tape boxes from both sides in the column direction. There is no need to set two side stops for each row of tape boxes, which reduces the investment in side stops and lowers costs.

[0023] Another further solution includes a second moving mechanism and an adsorption mechanism; driven by the first moving mechanism, the gripping mechanism moves between the carrier and the horizontally positioned rotating chamber; driven by the second moving mechanism, the adsorption mechanism moves between the vertically positioned rotating chamber and the loading station.

[0024] As can be seen above, once the tape box is adjusted to a vertically stacked and flat position by the rotating chamber, the top tape box can be removed and transferred to the loading station simply by using the suction mechanism to pick it up from above. The tape box loading machine automatically completes all actions from picking up the parts from the carrier, adjusting the posture, and placing them at the loading station.

[0033] Example of a box-type feeding machine See Figure 1 and Figure 2The box-loading machine of this embodiment includes a first moving mechanism 21 and a gripping mechanism 3 driven by the first moving mechanism 21, which can move horizontally and be raised and lowered; it also includes, for example, Figure 2 The second moving mechanism 22 shown includes a horizontally movable and vertically adjustable suction mechanism 6 driven by the second moving mechanism 22; a rotating chamber 4 that can rotatably change between a horizontal and a vertical state; and a carrier 9 stacked at the tray stacking station, with the cartridge 8 placed in the carrier 9. In this embodiment, the cartridge 8 refers to the bare shell of the printing consumable cartridge, which needs to be loaded and assembled.

[0034] Driven by the first moving mechanism 21, the gripping mechanism 3 can move to the carrier 9 to take out a row of upright and stacked tape boxes 8 and transfer them to the horizontal rotating chamber 4. At this time, the tape boxes 8 are placed vertically in the rotating chamber 4. The rotating chamber 4 rotates to the vertical position, thereby rotating the tape boxes 8 in the rotating chamber 4 to the flat position. Driven by the second moving mechanism 22, the adsorption mechanism 6 can move to the vertical rotating chamber 4, adsorb a flat tape box 8 and transfer it to the loading station.

[0035] See Figure 3 The carrier 9 is a material box. The carrier 9 includes multiple partitions 92, which are wall panels. A box placement space 90 is formed between every two partitions 92. The box placement space 90 is used to place a row of boxes 8.

[0036] See Figure 3 and Figure 4 The cassette feeding machine of the present invention also includes a side baffle 7. Each side baffle 7 has mating portions on opposite sides. The side baffle 7 is positioned within a cassette placement space 90, and each of the two mating portions abuts against two partition portions 92 on the left and right sides of the cassette placement space 90. More specifically, as shown... Figure 4 As shown, the side stop 7 includes a first elastic arm 71, a horizontal arm 72, and a second elastic arm 71 that extend in sequence by bending. The elastic arms 71 are the mating parts of the present invention, and a first clamping clearance opening 70 is formed between the two elastic arms 71 and the horizontal arm 72. The first clamping clearance opening 70 not only extends horizontally, but also has an upward opening 701, which is also formed between the two elastic arms 71.

[0037] The side stop 7 can be integrally molded from plastic or bent from a metal sheet. The elastic arm 71 is configured as a continuously bent shape to ensure better elastic deformation capability. Furthermore, the elastic arm 71 has an inclined segment 71a, which extends upward and gradually outward from the side stop 7.

[0038] Thus, after the side guard 7 is placed into the tape box placement space 90, the elastic arms 71 on both sides contract and deform after being squeezed by the partition 92. Through the rebound force of the elastic arms 71, the elastic arms 71 abut against the partition 92 to maintain the current state. In this way, when the upright and rowed tape boxes 8 are not fully placed in a row, the side guard 7 can block the first tape box 8 from the front of the rowing direction of the tape boxes 8 to prevent it from tipping over.

[0039] See also Figure 3 Along the length of the cassette placement space 90, that is, along the cassette 8 in the row direction, the side wall of the carrier 9 (the fourth side of the present invention) is provided with two support portions 91 that protrude toward the cassette placement space 90, and a second clamping clearance opening 910 is formed between the two support portions 91. The second clamping clearance opening 910 opens upward and communicates with the cassette placement space 90 along the row direction of the cassette 8.

[0040] See Figure 5 The gripping mechanism 3 includes two clamping members 31 arranged opposite each other. The gripping mechanism 3 can move the two clamping members 31 closer together or further apart. The gripping mechanism 3 also includes a motor 33 and a first belt drive assembly 32. The motor 33 drives the first belt drive assembly 32 to work. A follower on the first belt drive assembly 32, connected to the drive belt, is connected to one of the clamping members 31. Driven by the motor 33, the clamping member 31 can move closer to or further away from the other clamping member 31. By adjusting the distance between the two clamping members 31, different columns and different numbers of tape boxes 8 within different tape box placement spaces 90 can be clamped.

[0041] In addition, a laser sensor 391 and an optical fiber sensor 392 are installed on the movable clamping member 31, and a magnetic scale is provided on the gripping mechanism 3 for detecting the moving distance data of the clamping member 31. With the laser sensor 391, the optical fiber sensor 392 and the magnetic scale, the moving distance data of the clamping member 31 and the situation of the tape box 8 clamped between the two clamping members 31 can be detected.

[0042] In addition, a buffer block 311 is provided on the clamping side of the clamping member 31. The buffer block 311 is fixed to the main body of the clamping member 31 by a spring. The buffer block 311 helps to protect the strap box 8. Furthermore, the buffer member 311 can be made of cushioning materials such as rubber or silicone.

[0043] Combination Figures 3 to 5 The gripping mechanism 3 grips the same column of tape boxes 8 in the tape box placement space 90 each time. The first clamping clearance opening 70 and the second clamping clearance opening 910 allow the two clamping members 31 to enter respectively. In this embodiment, the clamping member 31 is configured as an elongated shape extending vertically. This configuration mainly makes the clamping member 31 narrower and longer, facilitating its entry into the first clamping clearance opening 70 and the second clamping clearance opening 910, which have limited widths.

[0044] like Figure 3 As shown, since the number of tape boxes in each order varies, the number of tape boxes 8 in each column of the multiple tape box placement spaces 90 may also vary. The side baffles 7 placed in the tape box placement space 90 block the first tape box 8 in each column, while the inner wall of the tape box placement space 90 blocks the last tape box 8. This ensures that tape boxes 8 in a partially filled column will not tip over. Furthermore, since the placement position of the side baffles 7 is not restricted, they can also be used to keep the multiple tape boxes 8 in an ideal state of close contact with each other. On the other hand, both the side baffles 7 and the carrier 9 have clearance openings, allowing each column of tape boxes 8 to be clamped by two clamping members 31.

[0045] See Figure 6 , Figure 6 The rotating chamber 4 is shown in a horizontal position with its inlet 401 open. A series of tape boxes 8 (at least one tape box 8) clamped from the carrier 9 will be inserted into the interior 40 of the rotating chamber 4 from its inlet 401.

[0046] See Figure 6 and Figure 7 The box-loading machine also includes a third moving mechanism 23 and a first drive unit 49. The first drive unit 49 is a motor, and its main body is connected to the moving end of the third moving mechanism 23. The rotating bin 4 is connected to the output shaft of the first drive unit 49. Driven by the third moving mechanism 23, the rotating bin 4 can translate; driven by the first drive unit 49, the rotating bin 4 can rotate at least 90 degrees to... Figure 6 The horizontal state shown has changed to Figure 8 The vertical position is shown. The third moving mechanism 23 drives the first driving unit 49 and the rotating chamber 4 to move synchronously, which facilitates the subsequent rotation of the rotating chamber 4 and prevents interference.

[0047] See Figure 6 The rotating chamber 4 has an entrance 401 along its first direction (the z-axis direction in the diagram) and an exit 402 along its second direction (the y-axis direction in the diagram). A row of tape boxes 8, gripped by the gripping mechanism 3, is fed into the interior 40 of the rotating chamber 4 from the entrance 401 along the first direction, and then grips the tape boxes 8 at the exit. The entrance 401 facilitates the placement of upright and row-shaped tape boxes 8 inside the rotating chamber 4; after the rotating chamber 4 rotates, the exit 402 facilitates the gripping mechanism 3 to grip tape boxes 8 that are placed horizontally.

[0048] See Figure 6 and Figure 7 The rotating chamber 4 is also provided with a movable stop 5, a second drive unit 59, a second belt drive assembly 58 and a slide rail assembly 57. The second belt drive assembly 58 is the transmission assembly of the present invention.

[0049] The rotating chamber 4 includes a first side portion 41, which is one of the wall panels constituting the interior 40 of the rotating chamber 4. The first side portion 41 is provided with an elongated hole 410 extending in a second direction. The second belt drive assembly 58 and the slide rail assembly 57 are both disposed on the outside of the first side portion 41, which is the side facing away from the interior 40 and towards the outside of the rotating chamber 4.

[0050] like Figure 6 As shown, the second drive unit 59 is a motor, and it is located outside the rotating chamber 4 in the second direction. The output shaft of the second drive unit 59 is connected to the input pulley of the second belt drive assembly 58. A portion of the movable stop 5 is connected to the follower 581 of the second belt drive assembly 58, which is fixed to the belt, on the outside of the first side portion 41. The other portion of the movable stop 5 extends into the interior 40 of the rotating chamber 4 through the elongated hole 410. Furthermore, the follower 581 of the second belt drive assembly 58 is also connected to the first side portion 41 via a slide rail assembly 57 arranged along the second direction. This arrangement ensures the stability and translational straightness of the follower 581.

[0051] like Figure 6 As shown, the portion of the movable stop 5 located inside 40 is provided with a third clamping clearance opening 50 for the clamping member 31 to enter. The third clamping clearance opening 50 extends through in the second direction and opens in the first direction.

[0052] See also Figure 6 and Figure 7 The rotating chamber 4 includes a second side 42 and a third side 43 arranged opposite each other in a third direction. The second side 42 and the third side 43 are both wall panels that constitute the interior 40 of the rotating chamber 4. The second side 42, the first side 41 and the third side 43 are connected to each other at right angles in sequence.

[0053] The rotating chamber 4 is equipped with a clamping mechanism 46, which is opposite to the second side 42 in the third direction (x-axis direction in the figure) inside the rotating chamber 4 to clamp the tape box 8 from the third direction.

[0054] The clamping mechanism 46 includes a fourth drive unit 462 and a clamping member 461. The fourth drive unit 462 is a cylinder and is located on the outside of the first side portion 41. The clamping member 461 is connected to the end of the piston rod of the fourth drive unit 462 via an extension and extends into the interior 40 through a through hole in the third side portion 43. In the second direction, the clamping member 461 is located near the outlet 402. The clamping mechanism 46 mainly clamps the first tape cassette 8 closest to the outlet 402. By clamping the tape cassette closest to the outlet 402 using the clamping mechanism 46, the first tape cassette will not fall from the outlet 402 when the rotating chamber 4 is horizontal. At this time, the first tape cassette acts as a barrier for the other tape cassettes, preventing them from falling from the outlet 402 as well.

[0055] Before the gripping mechanism 3 places a series of tape boxes 8 into the rotating chamber 4, the position of the movable stop 5 is adjusted according to the data obtained by the magnetic scale on the gripping mechanism 3. This setting ensures that the first tape box 8 in different series of tape boxes 8 with varying numbers is located near the outlet 402, opposite to the clamping member 461, while the last tape box 8 is blocked by the movable stop 5. Figure 6 As shown, the current batch of tape boxes 8 includes only one tape box 8. Therefore, the movable stop 5 is moved to a position very close to the exit 402. This single tape box 8 is both pressed by the clamping member 461 and blocked by the movable stop 5.

[0056] The rotating chamber 4 is also provided with a cover 44 that can block part of the entrance 401 and a third drive unit 451 that drives the cover 44 to move. In this embodiment, the cover 44 is a flip cover with the rotation axis along the second direction. The rotating chamber 4 also includes a rack 452 and a gear 453. The third drive unit 451 is a cylinder. The third drive unit 451 drives the rack 452 to move in a straight line. The gear 453 is coaxially rotatably connected to the flip cover, and the rack 452 meshes with the gear 453.

[0057] See Figure 6 and Figure 8 After the clamping member 461 and the movable stop 5 move into place and cooperate with the tape box 8, the gripping mechanism 3 leaves the range of motion of the cover 44, and the third drive unit 451 drives the cover 44 from... Figure 6 The location shown for opening entrance 401 is rotated to... Figure 8 The closed position, shown, partially blocks the inlet 401. Then, the rotating chamber 4 is controlled to move from... Figure 6 Rotate to the horizontal position shown Figure 8 The image shows the upright position.

[0058] When the rotating chamber 4 is in the upright position, the cover 44 blocking the inlet 401 prevents the tape box 8 from falling out of the inlet 401 and also plays a certain role in positioning the tape box 8. Therefore, the cover 44 does not need to be designed to completely block the inlet 401, thus avoiding unnecessary complexity in the design.

[0059] Combined Figure 2 When the rotating chamber 4 is in an upright position with the outlet 402 facing upwards, the movable stop 5 supports all the tape boxes 8 inside the rotating chamber 4 from below. Because the position of the movable stop 5 was accurately adjusted in the previous steps, regardless of the number of tape boxes 8 inside the rotating chamber 4, the uppermost tape box 8 is always positioned at a uniform height close to the outlet 402. Therefore, regardless of the number of tape boxes 8 inside the rotating chamber 4 each time, the subsequent adsorption mechanism 6 will retrieve the tape at a uniform height.

[0060] Since the outlet 402 is facing upwards at this time, the tape box 8 can no longer fall out of the outlet 402. At this time, the clamping mechanism 46 is released first to avoid affecting the subsequent picking operation. Then, the adsorption mechanism 6 takes out the top tape box 8 from the outlet 402. Each time a tape box 8 is taken out, the movable stop 5 is controlled to rise by the height of one tape box 8. The height at which the adsorption mechanism 6 picks up the tape box 8 is consistent each time.

[0061] Mainly, this invention provides a side stop 7 that can be locked in the tape box placement space 90 of the carrier 9 and has a first clamping clearance opening 70. When a row of tape boxes 8 is not full, the side stop 7 can be used to block that row of tape boxes 8 to prevent them from tipping over. Furthermore, it does not affect the clamping member 31 from clamping and removing the entire row of tape boxes 8 from the side in the rowing direction.

[0062] Furthermore, the present invention also designs a rotating chamber 4, which not only changes the multiple horizontally arranged and standing tape boxes to vertically stacked and lying flat, but also determines the target stroke of the movable stop 5 based on the detection data obtained when the gripping mechanism 3 grips, ensuring that the top tape box 8 is at a uniform height each time, so as to facilitate subsequent loading and unloading.

[0063] As can be seen, the present invention solves the problems of posture conversion of the tape box 8, tilting of the tape box 8, and inconsistent picking height, and realizes the automation of the feeding of the tape box 8.

[0064] In addition, the first moving mechanism, the second moving mechanism and the third moving mechanism in this invention are all implemented using means commonly used in the field of mechanical equipment to achieve linear movement, such as linear modules, lead screw assemblies, belt drive assemblies, etc.

[0065] In other embodiments, the mating parts of the side stop may not need to be elastic. For example, multiple slots can be provided on the partition of the carrier, equidistant from each other along the length of the cassette placement space. The two mating parts on both sides of the side stop are inserted into the two slots respectively, so that the side stop can be stably placed in the cassette placement space.

[0066] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
