Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a box-retrieving mechanism for a box packing machine. 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 carton-retrieving mechanism for a carton packing machine, which aims to solve the problem that the adjustment of the guide plate on the empty carton conveying mechanism of the carton packing machine in the prior art is relatively cumbersome.

[0006] To achieve the above objectives, one embodiment of the present invention provides a box-retrieving mechanism for a box packing machine, including an X-axis driving mechanism, a Y-axis driving mechanism mounted on the X-axis driving mechanism, a clamping mechanism mounted on the Y-axis driving mechanism, and a supporting mechanism parallel to and above the X-axis driving mechanism.

[0007] The Y-axis drive mechanism includes a housing, with a mounting plate fixed to one end of the housing. A bidirectional ball screw is rotatably connected inside the housing. Sliders are mounted on the two nuts of the bidirectional ball screw, and a slide rail is fixedly connected inside the housing. The sliders are slidably connected to the surface of the slide rail. A second servo motor is mounted on one side of the mounting plate. Synchronous pulleys are provided on the output shaft of the second servo motor and one end of the screw shaft of the bidirectional ball screw. The two synchronous pulleys are connected by a synchronous belt drive.

[0008] The clamping mechanism includes two bases, which are respectively mounted on the top of two sliders. Each of the two bases has a vertical plate fixedly connected to its top. Each of the two vertical plates has a clamping plate fixedly mounted on its opposite side, and each of the two clamping plates has a suction cup fixedly mounted on its opposite side.

[0009] The supporting mechanism includes two U-shaped grooves, and multiple rollers are rotatably connected inside the U-shaped grooves. A flipping cylinder is provided between the two U-shaped grooves, and the flipping cylinder is located at the feed end of the U-shaped groove. A limit plate is installed on the flip plate of the flipping cylinder.

[0010] The beneficial effects are:

[0011] Firstly, the two clamping plates of the clamping mechanism can be driven by the bidirectional ball screw to move closer or further away from each other synchronously. Thus, when the packaging box enters the supporting mechanism, if the position is offset, the two clamping plates can move synchronously to center the offset packaging box above the supporting mechanism when the clamping mechanism picks up the packaging box. Therefore, there is no need to set up a guide structure. When loading packaging boxes of different sizes, there is no need to manually adjust the guide structure. Therefore, the operation process is simpler when changing packaging boxes of different sizes.

[0012] Secondly, by setting suction cups on the inside of the clamping plate, the suction force of the suction cups is used to fix the packaging box. In this way, the clamping plate does not need to provide a large clamping force to the packaging box, thus avoiding the problem of deforming the packaging box and making it difficult to pack the tissues into the box later.

[0013] Third, by setting up a flip cylinder and setting a limit plate on the flip plate of the flip cylinder, the packaging box can be blocked to prevent subsequent packaging boxes from pushing each other, causing the packaging box to move to the packing position and squeezing out the packaging box that is being packed.

[0014] Furthermore, the X-axis driving mechanism includes a linear slide table. A fixing plate is provided at the bottom of the housing. The housing is fixedly mounted on the slide table of the linear slide table through the fixing plate, so that the linear slide table can drive the housing to move in the X direction. A motor frame is installed on one side of the linear slide table head. A servo motor is fixedly installed on the side of the motor frame away from the linear slide table. The output shaft of the servo motor is connected to the drive shaft of the linear slide table, so that the servo motor can drive the slide table of the linear slide table to move.

[0015] Furthermore, the X-axis drive mechanism also includes an aluminum crossbeam, the side of which is provided with a support. The aluminum crossbeam is fixed inside the packing machine by the support, and the linear slide is installed on top of the aluminum crossbeam.

[0016] In a preferred embodiment, the X-axis drive mechanism includes two aluminum crossbeams and two linear slides. The housing is fixedly mounted on the slides of the two linear slides via a fixing plate. For a longer housing, fixing it on the two linear slides provides more stable movement. Furthermore, the drive shafts of the two linear slides are connected via a transmission shaft, thus requiring only one servo motor to be installed on one side of one linear slide. This servo motor drives the slides on both linear slides, ensuring synchronization of the slides on the two linear slides.

[0017] Furthermore, a dust cover is installed on one side of the mounting plate to shield the two synchronous pulleys and provide a certain degree of dust protection.

[0018] Furthermore, a reinforcing plate is fixed at the angle between the base and the upright plate to reinforce the upright plate.

[0019] Furthermore, the supporting mechanism also includes two aluminum crossbeams, each with a fixing seat at both ends for fixing the two aluminum crossbeams inside the packing machine, and two U-shaped grooves installed on the top of the two aluminum crossbeams respectively.

[0020] Furthermore, a positioning seat is provided below the two aluminum crossbeams, and the tilting cylinder is mounted on the positioning seat.

[0021] In a preferred embodiment, a pusher plate is provided on the side of the two clamping plates near the discharge end of the U-shaped channel.

[0022] The beneficial effect is that when the clamping mechanism moves the empty box to the packing position, the pusher plate can push the full box away 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, which would prevent the empty box from accurately entering the packing position.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. 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.

[0033] 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.

[0034] This utility model provides a box-retrieving mechanism for a box-packing machine.

[0035] Example 1:

[0036] like Figure 1 As shown, it includes an X-axis drive mechanism 1, a Y-axis drive mechanism 2 mounted on the X-axis drive mechanism, a clamping mechanism 3 mounted on the Y-axis drive mechanism 2, and a supporting mechanism 4 that is parallel to and above the X-axis drive mechanism 1.

[0037] like Figure 2 As shown, the X-axis drive mechanism 1 includes an aluminum crossbeam 11 and a linear slide 13. A support 12 is provided on the side of the aluminum crossbeam 11, and the aluminum crossbeam 11 is fixed inside the packing machine through the support 12. The linear slide 13 is installed on the top of the aluminum crossbeam 11. A motor frame 14 is installed on one side of the head of the linear slide 13. A servo motor 15 is fixedly installed on the side of the motor frame 14 away from the linear slide 13. The output shaft of the servo motor 15 is connected to the drive shaft of the linear slide 13, so that the servo motor 15 can drive the slide on the linear slide 13 to move. The linear slide 13 is the prior art well known to those skilled in the art. Its internal structure and the way it is connected to the servo motor are also prior art, so they will not be described in detail in this application.

[0038] like Figure 3 and Figure 4As shown, the Y-axis drive mechanism 2 includes a housing 21, with a fixing plate 22 at the bottom. The housing 21 is fixedly mounted on a linear slide 13 via the fixing plate 22, allowing the linear slide 13 to drive the housing 21 to move in the X-axis. One end of the housing 21 is fixed with a mounting plate 23. A bidirectional ball screw 24 is rotatably connected inside the housing 21. The bidirectional ball screw 24 has two nuts and two threads on its screw shaft. The two threads rotate in opposite directions, and rotation of the screw shaft can bring the two threads closer or further apart. Slider 25 is mounted on each of the two nuts of the bidirectional ball screw 24. A slide rail 26 is fixedly connected to the slide rail 26, and a slider 25 is slidably connected to the surface of the slide rail 26, thereby rotating the screw shaft of the bidirectional ball screw 24, which can make the two sliders 25 move closer or further apart. A servo motor 27 is installed on one side of the mounting plate 23. The output shaft of the servo motor 27 and one end of the screw shaft of the bidirectional ball screw 24 both pass through the mounting plate 23. Synchronous pulleys 28 are provided on the output shaft of the servo motor 27 and one end of the screw shaft of the bidirectional ball screw 24. The two synchronous pulleys 28 are connected by a synchronous belt drive, so that the servo motor 27 can drive the two sliders 25 to move in the Y direction. A dust cover 29 is installed on one side of the mounting plate 23 to shield the two synchronous pulleys 28.

[0039] Preferred, such as Figure 1-2 As shown, the X-axis drive mechanism 1 includes two aluminum crossbeams 11 and two linear slides 13. The housing 21 is fixedly mounted on the slides of the two linear slides 13 by a fixing plate 22. For the long housing 21, the movement is more stable when fixed on the two linear slides 13. The drive shafts of the two linear slides 13 are connected by a transmission shaft 16. Thus, only one side of the linear slide 13 needs to be equipped with a servo motor 15, and one servo motor 15 drives the slides on the two linear slides 13 to move, which can ensure the synchronization of the slides on the two linear slides 13.

[0040] like Figure 3-4As shown, the clamping mechanism 3 includes two bases 31, which are respectively mounted on the tops of the two sliders 25. Each base 31 has a vertical plate 32 fixedly connected to its top. A reinforcing plate 36 is fixed at the angle between the bases 31 and the vertical plates 32 to reinforce the vertical plates 32. Clamping plates 33 are fixedly installed on opposite sides of each of the two vertical plates 32, and suction cups 34 are fixedly installed on opposite sides of each of the two clamping plates 33. A cable chain is installed inside the packing machine, with one end connected to the housing 21. A cable connected to the servo motor 27 and a suction cup 34 are also included. The suction cups connected to the plate 34 are all inserted into the cable chain, so that the cables and suction cups will not become tangled during the movement of the Y-axis drive mechanism 2 and the clamping mechanism 3. The two sliders 25 drive the two bases 31 to move closer to each other, thereby bringing the two clamping plates 33 closer to each other. When the suction cup 34 is attached to the side of the packaging box, the Y-axis drive mechanism 2 stops driving, and the suction cup 34 uses suction to adhere to the side of the packaging box, thus fixing the packaging box. In this way, the clamping plates 33 do not need to provide a large clamping force to the packaging box, thereby avoiding the problem of deforming the packaging box.

[0041] like Figure 5 As shown, the supporting mechanism 4 includes two aluminum crossbeams 41 and two U-shaped channels 43. Each of the two aluminum crossbeams 41 has a fixing seat 42 at its bottom end for fixing the two aluminum crossbeams 41 inside the packing machine. The two U-shaped channels 43 are respectively installed on the top of the two aluminum crossbeams 41, and multiple rollers 44 are rotatably connected inside the U-shaped channels 43. Figure 1 and Figure 5 As shown, a tilting cylinder 5 is provided between the two U-shaped grooves 43. The tilting cylinder 5 mainly includes a cylinder and a tilting plate structure. The cylinder can drive the tilting plate to tilt 90 degrees. The tilting cylinder 5 is prior art, and its specific structure will not be described in this application. The tilting cylinder 5 is located at the feeding end of the U-shaped groove 43. A positioning seat 52 is provided below the two aluminum crossbeams 41. The tilting cylinder 5 is installed on the positioning seat 52. A limit plate 51 is installed on the tilting plate of the tilting cylinder 5. When the tilting cylinder 5 drives the limit plate 51 to rotate and stand upright, the limit plate 51... The protrusion above the U-shaped groove 43 can block the packaging boxes and prevent them from pushing each other, causing them to move to the packing position and squeezing out the packaging boxes that are being packed. The two clamping plates 33 are equipped with push plates 35 on the side near the discharge end of the U-shaped groove 43. When the clamping mechanism 3 moves the empty box to the packing position, the push plates 35 can push the full box away in advance, avoiding the problem of empty boxes colliding with full boxes, causing the empty boxes to deform, or the empty boxes to be displaced relative to the suction cup 34, which would prevent the empty boxes from accurately entering the packing position.

[0042] The working principle of this utility model is as follows: Figure 6As shown, the box-retrieving mechanism is installed inside the box-packing machine. During operation, empty boxes are transported to the top of the supporting mechanism 4 via a conveyor belt. The limiting plate 51 on the tilting cylinder 5 then blocks the empty boxes. The X-axis drive mechanism 1 drives the clamping mechanism 3 to move towards the feed end of the supporting mechanism 4. When the two clamping plates 33 of the clamping mechanism 3 move to both sides of the first empty box, the Y-axis drive mechanism 2 drives the two clamping plates 33 closer to the empty box. When the suction cups 34 adhere to both sides of the empty box, the Y-axis drive mechanism 2 stops. The suction cup 34 vacuum-adheses and fixes the empty box, and then the flip cylinder 5 rotates the limiting plate 51 so that the limiting plate 51 is rotated to the bottom of the two U-shaped grooves 43. The X-direction drive mechanism 1 then drives the empty box to the packing position on the support mechanism 4 for packing. After the first empty box is removed, the flip cylinder 5 rotates the limiting plate 51 so that it protrudes above the U-shaped grooves 43 to block the empty boxes behind. When the packing position is full of boxes, the clamping mechanism 3 performs the box removal operation as described above.
