Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a box-retrieving mechanism that facilitates rapid box packing. Background Technology

[0002] In the tissue paper production process, a case packing machine is needed to pack multiple packs of tissue paper into boxes for easy transportation. The boxes are then transported to the packing area by a conveyor mechanism. Existing case packing machines typically use existing conveyor roller frames for conveying boxes. For example, in a fully automatic case packing machine disclosed in Chinese Patent CN111846431B, the empty carton conveying mechanism is a conveyor roller frame. The empty carton conveying mechanism transports the boxes to a position below a support block, which opens the opening of the box. A suction cup-type robotic arm then places multiple packs of tissue paper into the box. However, because it needs to accommodate packaging boxes of different sizes and ensure that the boxes can accurately enter under the support block, the empty carton conveying mechanism usually needs to be equipped with two adjustable guide plates. These guide plates limit the sides of the carton after it enters the conveying mechanism, ensuring accurate entry under the support block. However, the existing adjustable guide plates on the empty carton conveying mechanism are quite long, typically requiring multiple adjusting screws for positioning. Therefore, this presents the following drawbacks during adjustment:

[0003] The adjustment of the guide plates requires manual adjustment of the adjusting screws of multiple positioning guide plates. Therefore, when changing to packaging boxes of different sizes, the adjustment process of the guide plates is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0005] Therefore, one objective of this utility model is to propose a box-retrieving mechanism that facilitates rapid box packing, aiming to solve the problem that the adjustment of the guide plate on the empty carton conveying mechanism of the existing box packing machine is relatively cumbersome.

[0006] To achieve the above objectives, one embodiment of the present invention provides a box-retrieving mechanism for quick box packing, comprising two bases, two linear slides, two linear slides, two clamping assemblies, and two U-shaped grooves;

[0007] Two linear slides are respectively installed on the top of two bases, and each of the two bases is provided with a support seat. One linear slide is installed on the top of the two support seats, and the other linear slide is installed on the slide structure of the two linear slides. Two clamping assemblies are respectively fixedly installed on the slide structure of the two linear slides. The machine head at both ends of the linear slide installed on the linear slide is provided with a bracket.

[0008] Both U-shaped grooves are rotatably connected to multiple rollers inside. One of the U-shaped grooves is fixedly installed on the top of the two supports, and the other U-shaped groove is fixedly installed on the side of the case packer near the paper towel conveying mechanism, so that the linear slide can drive one U-shaped groove to move. Guide plates are fixedly installed on the outer sides of both U-shaped grooves.

[0009] The beneficial effects are:

[0010] Firstly, two linear slides can drive one of the linear slides, thereby moving the clamping components and U-shaped grooves on the linear slide. This allows for adjustment of the spacing between the guide plates on the two U-shaped grooves, making it suitable for packaging boxes of different widths. Moreover, the adjustment of the guide plates does not require manual operation, making the operation simple, time-saving, and labor-saving.

[0011] Secondly, the stationary U-shaped troughs are fixed inside the case packer on the side closest to the tissue paper conveying mechanism. Therefore, no matter how the distance between the two guide plates is adjusted according to the width of the packaging box, the packaging boxes on the two U-shaped troughs will always be closest to the tissue paper side inside the case packer. As a result, the robot arm has the shortest stroke when picking up and placing tissue paper, which can improve the efficiency of case packing and achieve the purpose of energy saving.

[0012] Furthermore, a motor bracket is installed on one side of one of the linear slide heads, and a servo motor is fixedly installed on one side of the motor bracket. The output shaft of the servo motor is connected to the input end of the linear slide head. The heads of the two linear slides are connected by a transmission shaft, so that one servo motor can drive the slide mechanism of the two linear slides to move.

[0013] In a preferred embodiment, one of the bases is provided with a ball spline on its top, and a second servo motor is also installed on the top of the base. The output shaft of the second servo motor is connected to one end of the spline shaft of the ball spline via a coupling. A first synchronous pulley is fixedly installed on the spline shaft of the ball spline, and a second synchronous pulley is installed on the outer flange of the spline cylinder of the ball spline. The input shaft ends of the two linear slide heads are each fixedly installed with a third synchronous pulley. The two third synchronous pulleys are respectively connected to the first and second synchronous pulleys via synchronous belt drives.

[0014] Furthermore, a traction plate is installed at the bottom of one of the brackets, and the outer spline cylinder of the ball spline is rotatably connected inside the traction plate. Therefore, during the process of linear slide one driving linear slide two to move, the bracket pushes the outer spline cylinder of the ball spline to move through the traction plate, thereby achieving the purpose of moving synchronous pulley two, which can avoid the problem of the synchronous belt on synchronous pulley two and synchronous pulley three falling off during the adjustment process.

[0015] The beneficial effects are as follows: by setting the ball spline and traction plate, the synchronous wheel 2 used for driving the movable linear slide 2 can slide, so that the two linear slides 2 can be driven simultaneously by one servo motor 2, thereby ensuring the synchronization of the two linear slides 2 and achieving the purpose of making the two clamping components move in the same direction and at the same speed.

[0016] In a preferred embodiment, the clamping assembly includes a housing, which is fixedly mounted on the slide structure of the linear slide table II. A drive cylinder is fixedly mounted inside the housing. A push plate is fixedly mounted on the piston rod end of the drive cylinder. A slide plate is fixedly mounted on the top of the push plate. A base is fixedly mounted on the top of the slide plate. A vertical plate is fixedly mounted on the top of the base. A clamping plate is fixedly mounted on the inner side of the vertical plate. A suction cup is fixedly mounted on the inner side of the clamping plate. The suction cup is connected to a suction tube, and the suction tube is connected to a vacuum pump for vacuum adsorption to fix the empty box.

[0017] The beneficial effect is that by setting suction cups on the inside of the clamping plate, the packaging box can be fixed by the suction of the suction cups. In this way, the clamping plate does not need to provide a large clamping force on the packaging box, thereby avoiding the problem of deforming the packaging box and making it difficult to pack the tissues into the box later.

[0018] Furthermore, a guide rail is fixedly installed inside the housing, and a slider is slidably connected above the guide rail. The slide plate is also fixed to the top of the slider, which can improve the stability of the slide plate movement.

[0019] Furthermore, a top plate is fixedly installed on one side of the clamping plate.

[0020] The beneficial effect is that when the clamping component moves the empty box to the packing position, the top plate can push away the full box in advance, avoiding the problem of the empty box colliding with the full box, causing the empty box to deform or the empty box to be displaced relative to the suction cup, resulting in the empty box not being accurately placed into the packing position.

[0021] In a preferred embodiment, a tilting cylinder is installed at the feed end on the outer side of the U-shaped channel. A baffle is installed on the tilting cylinder to block empty packaging boxes and prevent subsequent packaging boxes from pushing each other, causing the packaging boxes to move to the packing position and squeezing out the packaging boxes that are being packed.

[0022] The beneficial effects are as follows: by setting up a flip cylinder and setting a baffle on the flip plate of the flip cylinder, the packaging box can be blocked, avoiding the problem of subsequent packaging boxes pushing each other, causing the packaging box to move to the packing position and squeezing out the packaging box that is being packed.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] This invention provides a box-retrieving mechanism that facilitates rapid box packing.

[0033] Example 1:

[0034] like Figure 1 As shown, it includes two bases 1, two linear slides 21, two linear slides 31, two clamping assemblies 4, and two U-shaped grooves 51.

[0035] like Figure 1 As shown, two linear slides 21 are respectively mounted on the top of two bases 1. A motor bracket 22 is mounted on one side of the head of one of the linear slides 21. A servo motor 23 is fixedly mounted on one side of the motor bracket 22. The output shaft of the servo motor 23 is connected to the input end of the head of the linear slide 21. The heads of the two linear slides 21 are connected by a transmission shaft 24, so that the servo motor 23 can drive the slide mechanism of the two linear slides 21 to move.

[0036] like Figure 1-2 As shown, each of the two bases 1 is provided with a support seat 11 on its top. One linear slide 2 31 is installed on the top of the two support seats 11, and the other linear slide 2 31 is installed on the slide structure of the two linear slides 1 21. Thus, the two linear slides 1 21 can drive one linear slide 2 31 to move, thereby achieving the purpose of adjusting the distance between the two linear slides 2 31.

[0037] like Figure 1As shown, a ball spline 12 is provided on the top of one of the bases 1, and a servo motor 2 13 is also installed on the top of the base 1. The spline shaft of the ball spline 12 is installed on the top of the base 1 through multiple bearing seats. The output shaft end of the servo motor 2 13 is connected to one end of the spline shaft of the ball spline 12 through a coupling. A synchronous pulley 14 is fixedly installed on the spline shaft of the ball spline 12. The ball spline 12 is of type SLF, and a flange is provided on its spline outer cylinder. A synchronous pulley 2 15 is installed on the flange of the spline outer cylinder of the ball spline 12. Thus, the synchronous pulley 2 15 can slide on the surface of the spline shaft through the spline outer cylinder and can also be driven to rotate by the spline shaft. The input shaft ends of the two linear slide tables 2 31 are fixedly installed with synchronous pulleys 3 32. The two synchronous pulleys 3 32 are respectively connected to synchronous pulleys 1 14 and synchronous pulleys 2 15 through synchronous belt drive.

[0038] like Figure 1 As shown, brackets 33 are installed on both ends of the machine head of the linear slide 21 mounted on the linear slide 21. A traction plate 34 is installed at the bottom of one of the brackets 33. The traction plate 34 has a bearing inside, and the spline outer cylinder of the ball spline 12 is fixed inside the bearing, so that the spline outer cylinder is rotatably connected to the traction plate 34. Therefore, during the process of the linear slide 21 driving the linear slide 21 to move, the bracket 33 pushes the spline outer cylinder of the ball spline 12 to move through the traction plate 34, thereby achieving the purpose of moving the synchronous pulley 2 15. This can avoid the problem of the synchronous belt on the synchronous pulley 2 15 and the synchronous pulley 32 falling off during the adjustment process.

[0039] like Figure 1-3 As shown, the clamping assembly 4 includes a housing 41, which is fixedly mounted on the slide structure of the linear slide 31, so that the two linear slides 31 can drive the two clamping assemblies 4 to move in the X direction. The housing 41 is fixedly mounted with a drive cylinder 42 and a guide rail 43. The piston rod end of the drive cylinder 42 is fixedly mounted with a push plate 44. The top of the push plate 44 is fixedly mounted with a slide plate 45. The guide rail 43 is slidably connected to a slider 46. The slide plate 45 is also fixedly mounted on the top of the slider 46. The top of the slide plate 45 is fixedly mounted with a base 47. The top of the base 47 is fixedly mounted with a vertical plate 48. The inner side of the vertical plate 48 is fixedly mounted with a clamping plate 49. The inner side of the clamping plate 49 is fixedly mounted with a suction cup 410. The suction cup 410 is connected to a suction tube, which is connected to a vacuum pump for vacuum adsorption to fix the empty box. The clamping plate 49 is fixedly mounted with a top plate 411 on one side.

[0040] like Figure 1 and Figure 4As shown, multiple rollers 52 are rotatably connected inside both U-shaped grooves 51. One U-shaped groove 51 is fixedly installed on the top of the two supports 33, and the other U-shaped groove 51 is fixedly installed on the side of the packing machine near the paper towel conveying mechanism, so that the linear slide 21 can drive one U-shaped groove 51 to move, thereby achieving the purpose of adjusting the distance between the two U-shaped grooves 51.

[0041] like Figure 1 As shown, guide plates 53 are fixedly installed on the outer sides of the two U-shaped grooves 51 to prevent cartons from slipping off the U-shaped grooves 51. A flipping cylinder 54 is installed at the feeding end on the outer side of the U-shaped grooves 51. The flipping cylinder 54 mainly includes a cylinder and a flipping plate structure. The cylinder can drive the flipping plate to flip 90 degrees. The flipping cylinder 54 is prior art, and the specific structure of the flipping cylinder 54 will not be described in this application. A baffle 55 is installed on the flipping plate of the flipping cylinder 54 to block empty packaging boxes and prevent subsequent packaging boxes from pushing each other, causing the packaging boxes to move to the packing position and squeezing out the packaging boxes that are being packed.

[0042] The working principle of this utility model is as follows: Two bases 1 are installed inside the case packing machine, and one of the U-shaped grooves 51 is fixed inside the case packing machine near the paper towel conveying mechanism. In use, empty boxes are transported to the top of the two U-shaped grooves 51 by the conveyor belt. The shift 55 on the flip cylinder 54 blocks the empty boxes. The two linear slides 31 drive the two clamping components 4 to move to the sides of the empty boxes. The drive cylinder 42 drives the clamping plate 49 to approach the empty boxes until the suction cup 410 adheres to the side of the empty boxes. The purpose of clamping and fixing the empty boxes is achieved by vacuum adsorption. Then, the flip cylinder 54 flips the baffle 55. The linear slides 31 then drive the two clamping components 4 to move to the case packing position above the U-shaped groove 51. After the first empty box is removed, the flip cylinder 54 rotates the baffle 55 to block the empty boxes behind. When the case packing position is full, the clamping components 4 can perform the case removal operation as described above.
