Description

Technical Field

[0001] The present application relates to the field of packaging technology, and in particular to a box supply device and packaging equipment. Background Art

[0002] Currently, there are production lines that can mechanically load materials into packaging boxes. In this process, mechanical equipment usually takes out packaging boxes from a box supply. In order to facilitate loading more packaging boxes, the box supply usually folds the packaging boxes into a flat shape and stacks them. Therefore, the taken packaging boxes need to be unfolded from a flat shape to a three-dimensional shape before the materials can be loaded.

[0003] However, the thickness of each side of the box is not exactly the same, e.g. Figure 1 The three-dimensional packaging box 200 is shown in FIG. 1 , and the right side of the packaging box has two layers, and the other sides have one layer; when the packaging box is folded into a flat shape, as shown in FIG. Figure 2 As shown, the first thickness portion 201 of the flat packaging box 200 is two layers, and the second thickness portion 202 is three layers. Since the thickness of the two thickness portions are different, when multiple packaging boxes 200 are stacked, the packaging box 200 as a whole will tilt toward the thinner side, and the more the stacked boxes are, the greater the tilt of the subsequent packaging boxes will be, which is more unfavorable for mechanical equipment to perform box taking operations.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the present application, not all the implementation modes. Based on the implementation mode in the present application, all other implementation modes obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0033] At present, the thickness of each side of some packaging boxes is not exactly the same, for example Figure 2 The figure shows a flat packaging box 200, which has a first thickness portion 201 and a second thickness portion 202. The thickness of the first thickness portion 201 is less than the thickness of the second thickness portion 202. When multiple packaging boxes 200 are stacked, the packaging box 200 as a whole will tilt toward one side of the first thickness portion 201. The greater the tilt of the packaging box 200, the more unfavorable it is for the mechanical equipment to perform the box-taking operation.

[0034] Based on this, see Figure 3 and Figure 4The embodiment of the present application provides a box supply device 100, which can be applied to the above-mentioned packaging box 200 to adapt to the packaging box 200 having different thicknesses and can still effectively perform the box removal operation. The box supply device 100 includes a frame 10, a box removal mechanism 30 and a box push mechanism 50. The box removal mechanism 30 and the box push mechanism 50 are both installed on the frame 10, and the box push mechanism 50 is arranged opposite to the box removal mechanism 30. The frame 10 can be used to load the packaging box 200, and the box push mechanism 50 can push the packaging box 200 to the box removal mechanism 30, and the box removal mechanism 30 can take out the packaging box 200 located on the frame 10.

[0035] See also Figure 5 and Figure 6 The frame 10 may include a base 11, a first lever assembly 13 and a second lever assembly 15. Both the first lever assembly 13 and the second lever assembly 15 may be mounted on the base 11. The first lever assembly 13 and the second lever assembly 15 may be arranged opposite to each other. The box pushing mechanism 50 may also be mounted on the base 11.

[0036] The base 11 can be used as a connecting piece of the frame 10 to achieve the connection and coordination between the frame 10 and other structures. The base 11 can carry the packaging box 200, so that the first gear lever assembly 13, the box taking mechanism 30, the second gear lever assembly 15 and the box pushing mechanism 50 can jointly surround the packaging box 200, thereby helping the frame 10 to better load the packaging box 200. After the base 11 carries the packaging box 200, the first thickness portion 201 of the packaging box 200 can be closer to the first gear lever assembly 13 relative to the second gear lever assembly 15, and the second thickness portion 202 of the packaging box 200 can be closer to the second gear lever assembly 15 relative to the first gear lever assembly 13.

[0037] The first gear lever assembly 13 is slidably mounted on the base 11. The sliding of the first gear lever assembly 13 relative to the base 11 can change the distance between the first gear lever assembly 13 and the second gear lever assembly 15. This helps the frame 10 to adjust the distance between the first gear lever assembly 13 and the second gear lever assembly 15 according to the size of the packaging box 200, so that the frame 10 can be adapted to load packaging boxes 200 of different sizes.

[0038] The first lever assembly 13 and the base 11 may be provided with corresponding structures to achieve sliding connection. For example, the base 11 may include a base body 111 and a first slide bar 113. The first slide bar 113 may be connected to the base body 111. The first slide bar 113 may be located on the side of the base body 111 away from the second lever assembly 15. The length direction of the first slide bar 113 may be from the second lever assembly 15 to the first lever assembly 13. Then, the first lever assembly 13 may be slidably sleeved on the first slide bar 113, thereby achieving sliding connection between the first lever assembly 13 and the base 11. In addition, when the first lever assembly 13 slides to a suitable spacing relative to the second lever assembly 15, the box supply device 100 may also use fasteners such as screws and bolts to lock the first lever assembly 13 and the base 11, thereby helping to prevent the frame 10 from vibrating, bumping, etc. due to external forces, thereby causing the position of the first lever assembly 13 relative to the base 11 to change.

[0039] The first gear lever assembly 13 may include a first base frame 131 , a first rod body 133 , a second rod body 135 and a first connecting bracket 137 . The first rod body 133 may be mounted on the first base frame 131 , and the first connecting bracket 137 may be connected to the first rod body 133 and the second rod body 135 , respectively.

[0040] The first base frame 131 can be installed on the base 11, for example, the first base frame 131 can be slidably mounted on the first slide bar 113 of the base 11. The first rod body 133 can be fixed to the first base frame 131, and the length direction of the first rod body 133 can be perpendicular to the length direction of the first slide bar 113. The second rod body 135 can be fixed to the first connecting bracket 137, and the length direction of the second rod body 135 can be perpendicular to the length direction of the first rod body 133, and can also be perpendicular to the length direction of the first slide bar 113. The first connecting bracket 137 can be slidably connected to the first rod body 133, and the direction in which the first connecting bracket 137 slides relative to the first rod body 133 can be the length direction of the first rod body 133, so that the second rod body 135 can slide relative to the first rod body 133 to different positions through the first connecting bracket 137, so that the height range between the second rod body 135 and the base 11 can be adjusted, which helps the frame 10 to be adapted to load packaging boxes 200 of different heights.

[0041] In addition, when the second rod 135 slides to a suitable height relative to the base 11, the box supply device 100 can also be locked with fasteners such as screws and bolts. For example, the fastener can be installed on the first connecting bracket 137 and connected to the second rod 135, so that the relative position between the second rod 135 and the first rod 133 remains unchanged, which helps to avoid external forces causing the frame 10 to vibrate, bump, etc., which may cause the position of the second rod 135 relative to the base 11 to change.

[0042] The second lever assembly 15 can be fixed to the base 11, or can be slidably installed on the base 11. When the second lever assembly 15 is fixed to the base 11, the second lever assembly 15 can be fixed to the base 11 by means of snap, thread connection, gluing, etc. When the second lever assembly 15 is slidably installed on the base 11, the sliding of the second lever assembly 15 relative to the base 11 can change the distance between the second lever assembly 15 and the first lever assembly 13. Since the first lever assembly 13 can also be slidably installed on the base 11, it is helpful for the frame 10 to adjust the distance between the second lever assembly 15 and the first lever assembly 13 according to actual conditions through at least one of the second lever assembly 15 and the first lever assembly 13, so that the adjustment method of the frame 10 is more flexible.

[0043] The second lever assembly 15 and the base 11 can be slidably connected by the same structure as the first lever assembly 13 being slidably connected to the base 11. For example, the base 11 can also include a second slide bar (not shown), which can be connected to the base body 111. The second slide bar can be located on a side of the base body 111 away from the first lever assembly 13. The length direction of the second slide bar can be from the first lever assembly 13 to the second lever assembly 15. The second lever assembly 15 can be slidably sleeved on the second slide bar, so that the second lever assembly 15 and the base 11 can be slidably connected.

[0044] In addition, when the second lever assembly 15 slides to a suitable spacing relative to the first lever assembly 13, the box supply device 100 can also use fasteners such as screws and bolts to lock the second lever assembly 15 and the base 11, thereby helping to prevent external forces from causing the frame 10 to vibrate, bump, etc., which may cause the position of the second lever assembly 15 relative to the base 11 to change.

[0045] The second gear lever assembly 15 may include a second base frame 151 , a third rod 153 , a fourth rod 155 and a second connecting bracket 157 . The third rod 153 may be mounted on the second base frame 151 , and the second connecting bracket 157 may be connected to the third rod 153 and the fourth rod 155 , respectively.

[0046] The second base frame 151 can be installed on the base 11. When the second lever assembly 15 is fixed to the base 11, the second base frame 151 can be fixed to the base 11. When the second lever assembly 15 is slidably installed on the base 11, the second base frame 151 can be slidably sleeved on the second slide bar of the base 11.

[0047] The third rod 153 can be fixed to the second base frame 151, and the length direction of the third rod 153 can be perpendicular to the length direction of the second slide bar. The fourth rod 155 can be fixed to the second connecting bracket 157, and the length direction of the fourth rod 155 can be perpendicular to the length direction of the third rod 153, and can also be perpendicular to the length direction of the second slide bar. The second connecting bracket 157 can be slidably connected to the third rod 153, and the direction in which the second connecting bracket 157 slides relative to the third rod 153 can be the length direction of the third rod 153, so that the fourth rod 155 can slide to different positions relative to the third rod 153 through the second connecting bracket 157, so that the height range between the fourth rod 155 and the base 11 can be adjusted, which helps to adapt to packaging boxes 200 of different heights.

[0048] In addition, when the fourth rod 155 slides to a suitable height relative to the base 11, the box supply device 100 can also be locked with fasteners such as screws and bolts. For example, the fastener can be installed on the second connecting bracket 157 and connected to the third rod 153, so that the relative position between the fourth rod 155 and the third rod 153 remains unchanged, which helps to avoid external forces causing the frame 10 to vibrate, bump, etc., which may cause the position of the fourth rod 155 relative to the base 11 to change.

[0049] See also Figure 4 and Figure 7 , the box taking mechanism 30 can take out the packaging box 200 located on the frame 10. The box taking mechanism 30 can be installed on the first lever assembly 13 in a liftable manner, which helps the box supply device 100 to adjust the height of the box taking mechanism 30 relative to the base 11 according to the size of the packaging box 200, making it easier for the box taking mechanism 30 to perform the box taking operation. The box taking mechanism 30 can be installed on the first connecting bracket 137 of the first lever assembly 13. Since the first connecting bracket 137 is slidably installed on the first rod body 133, the sliding of the first connecting bracket 137 relative to the first rod body 133 can realize the lifting and lowering of the box taking mechanism 30, and also avoids the need for an additional lifting component between the box taking machine and the first lever assembly 13, which helps to simplify the structure of the box supply device 100 and reduce costs.

[0050] See also Figure 8 The box taking mechanism 30 may include a box taking bracket 31 , a box body suction member 33 and a box taking power unit 35 . Both the box body suction member 33 and the box taking power unit 35 may be installed on the box taking bracket 31 .

[0051] The box body suction member 33 can be installed on the surface of the box taking bracket 31 facing the box pushing mechanism 50, and the box body suction member 33 is used to suck the packaging box 200. For example, the box body suction member 33 can be a suction cup, and the box body suction member 33 can be connected to the vacuum pump of the box supply device 100 through a vacuum tube, so that when the box body suction member 33 is attached to the surface of the packaging box 200, the box body suction member 33 can suck the packaging box 200 under the action of the vacuum pump.

[0052] The box taking power unit 35 can be connected between the box taking bracket 31 and the frame 10, and the box taking power unit 35 can drive the box taking bracket 31 to selectively move toward or away from the box pushing mechanism 50. The box taking power unit 35 can be a cylinder, and the cylinder body of the box taking power unit 35 can be connected to the first gear lever assembly 13, and the piston rod of the box taking power unit 35 can be connected to the box taking bracket 31.

[0053] For example, when the box supply device 100 needs to take out the packaging box 200, the box taking power unit 35 can drive the box taking bracket 31 to move toward the box pushing mechanism 50. Since the box pushing mechanism 50 and the box taking mechanism 30 are suitable for accommodating the packaging box 200, the box body suction piece 33 can be attached to the surface of the packaging box 200 to facilitate sucking the packaging box 200. After the box body suction piece 33 sucks the packaging box 200, the box taking power unit 35 can drive the box taking bracket 31 to move away from the box pushing mechanism 50 to facilitate taking out the packaging box 200.

[0054] The box taking mechanism 30 may further include a support guide rod 37, which is connected to the box taking support 31. For example, the support guide rod 37 may be fixedly connected to the box taking support 31 by means of snap, thread connection, gluing, etc. The support guide rod 37 may also be slidably connected to the first gear rod assembly 13. For example, the support guide rod 37 may penetrate the first gear rod assembly 13. In this way, when the box taking power unit 35 drives the box taking support 31 to move, the support guide rod 37 helps to improve the stability of the movement of the box taking support 31, and effectively ensures that the box taking support 31 will not be too vibrated during the movement, causing the packaging box 200 to be separated from the box body suction member 33.

[0055] See also Figure 4 and Fig. 9 The box pushing mechanism 50 includes a main box pushing component 51 and an auxiliary box pushing component 53. The auxiliary box pushing component 53 can be installed on the main box pushing component 51. The box pushing mechanism 50 pushes the packaging box 200 together through the main box pushing component 51 and the auxiliary box pushing component 53.

[0056] The main box pushing assembly 51 is suitable for pushing the packaging box 200 toward the box taking mechanism 30, thereby helping to push the packaging box 200 toward the box taking mechanism 30. The main box pushing assembly 51 may include a main box pushing member 511 and a main box pushing power unit 513, and the main box pushing member 511 may be installed on the main box pushing power unit 513.

[0057] The main push box push member 511 can be driven by the main push box power unit 513 to resist the packaging box 200. The main push box push member 511 can be flat, and the width of the main push box push member 511 can be smaller than the distance between the first gear lever assembly 13 and the second gear lever assembly 15, so as to facilitate the main push box push member 511 to move in the interval space between the first gear lever assembly 13 and the second gear lever assembly 15 to push the packaging box 200 toward the box taking mechanism 30.

[0058] The position where the main box pushing member 511 abuts against the packaging box 200 will change according to the number of packaging boxes 200. When the frame 10 is loaded with a large number of packaging boxes 200, the packaging boxes 200 will be tilted toward the thinner side (the first thickness portion 201) after being stacked, so that the second thickness portion 202 of each packaging box 200 is closer to the main box pushing member 511 than the first thickness portion 201. In the initial stage, the main box pushing member 511 will usually abut against the second thickness portion 202 of the packaging box 200 to push the packaging box 200 toward the box taking mechanism 30. As the number of packaging boxes 200 on the frame 10 decreases, the position where the main box pushing member 511 abuts against the packaging box 200 will shift from the second thickness portion 202 to the first thickness portion 201.

[0059] The main box pushing power unit 513 can be installed on the frame 10, for example, the main box pushing power unit 513 can be installed on the base 11 of the frame 10. The main box pushing power unit 513 can drive the main box pushing member 511 to slide relative to the frame 10, so that the main box pushing member 511 is suitable for pushing the packaging box 200 toward the box taking mechanism 30. The main box pushing power unit 513 can be an electric cylinder, and the main box pushing member 511 can be fixed to the slider of the main box pushing power unit 513 by fasteners such as screws and bolts.

[0060] See also Figure 4 and Fig.10The auxiliary box pushing assembly 53 is suitable for pushing the first thickness portion 201 of the packaging box 200 toward the box taking mechanism 30, and the thickness of the first thickness portion 201 of the packaging box 200 is less than the thickness of the second thickness portion 202. Since the box pushing mechanism 50 additionally pushes the thinner part of the packaging box 200 through the auxiliary box pushing assembly 53, it helps to straighten and flatten the packaging box 200, so that the first thickness portion 201 of the packaging box 200 is also as close to the box taking mechanism 30 as possible, which further facilitates the box taking operation of the box taking mechanism 30 and improves the box taking success rate of the box taking mechanism 30.

[0061] The auxiliary push box assembly 53 can be connected to the main push box assembly 51. For example, the auxiliary push box assembly 53 can be connected to the main push box push piece 511. Then, the sliding of the main push box push piece 511 relative to the frame 10 can drive the auxiliary push box assembly 53 to slide, ensuring that when the main push box push piece 511 moves toward the packaging box 200, the auxiliary push box assembly 53 can also move toward the packaging box 200 synchronously, thereby helping the auxiliary push box assembly 53 to maintain the push against the first thickness portion 201 of the packaging box 200.

[0062] The auxiliary push box assembly 53 may include an auxiliary push box bracket 531 , an auxiliary push box push member 533 and an auxiliary push box power unit 535 . The auxiliary push box power unit 535 may be installed on the auxiliary push box bracket 531 , and the auxiliary push box push member 533 may be connected to the auxiliary push box power unit 535 .

[0063] The auxiliary push box pushing member 533 can be located on the side of the main push box pushing member 511 facing the box taking mechanism 30. The auxiliary push box pushing member 533 can be driven by the auxiliary push box power unit 535 to resist the first thickness portion 201 of the packaging box 200. The auxiliary push box pushing member 533 can be in the shape of a flat plate, for example, the auxiliary push box pushing member 533 can be a rectangular plate, and the length direction of the auxiliary push box pushing member 533 can be parallel to the length direction of the first rod body 133.

[0064] The auxiliary box support 531 can be installed on the main box push member 511, for example, the auxiliary box support 531 can be fixed to the main box push member 511 by snapping, threading, gluing, etc. The auxiliary box support 531 can be located on the side of the main box push member 511 away from the box removal mechanism 30.

[0065] The auxiliary push box power unit 535 can be connected between the auxiliary push box bracket 531 and the auxiliary push box pushing member 533. The auxiliary push box power unit 535 can drive the auxiliary push box pushing member 533 to slide relative to the auxiliary push box bracket 531, so that the auxiliary push box pushing member 533 is suitable for pushing the first thickness portion 201 toward the direction of the box taking mechanism 30.

[0066] The auxiliary push box power unit 535 may include an auxiliary push box guide rod 5351 and an elastic member 5353. The auxiliary push box guide rod 5351 is connected to the auxiliary push box bracket 531 and is penetrated by the auxiliary push box pushing member 533. The elastic member 5353 is sleeved on the auxiliary push box guide rod 5351 and is respectively connected to the auxiliary push box bracket 531 and the auxiliary push box pushing member 533. The elastic member 5353 can provide the auxiliary push box pushing member 533 with a thrust toward the box taking mechanism 30. For example, the elastic member 5353 can be a compression spring, and the elastic member 5353 can be in a compressed state. In this way, the auxiliary push box pushing member 533 can straighten and flatten the packaging box 200 in real time, thereby helping the auxiliary push box pushing member 533 to keep the first thickness portion 201 of the packaging box 200 in a pushing state.

[0067] See also Fig.11 and Fig.12 The box supply device 100 may further include a workbench 70 and a telescopic power unit 90, and the frame 10 may be rotatably mounted on the workbench 70, for example, in combination with Fig.13 As shown, the frame 10 may further include a rotating shaft 17, which may be installed at the bottom of the base 11. The rotating shaft 17 may be matched with a bearing and installed on a bearing seat of the workbench 70, thereby realizing a rotational connection between the frame 10 and the workbench 70.

[0068] The telescopic power unit 90 can be connected between the workbench 70 and the frame 10. The telescopic movement of the telescopic power unit 90 drives the frame 10 to rotate relative to the workbench 70, so that the frame 10 can be rotated to a suitable angle to facilitate the worker to place the packaging box 200 on the frame 10, and after the worker completes the material placement operation, the frame 10 can be reversely rotated and reset to facilitate the box supply device 100 to continue to supply boxes. The telescopic power unit 90 can be a telescopic cylinder, the cylinder body of the telescopic power unit 90 can be hinged to the workbench 70, and the piston rod of the telescopic power unit 90 can be hinged to the base 11 of the frame 10.

[0069] The box supply device 100 may further include a stopper 40 and an oil pressure buffer 60, both of which may be mounted on the workbench 70 via a bracket. The stopper 40 may be located in the rotation path of the frame 10 relative to the workbench 70, thereby limiting the angle and position of the frame 10 relative to the workbench 70, which helps ensure that the box taking mechanism 30 of the box supply device 100 delivers the taken-out packaging box 200 to a position corresponding to the lower station. The oil pressure buffer 60 may buffer the impact force between the stopper 40 and the frame 10, which helps reduce the amplitude of the vibration of the frame 10 and the noise, and helps the frame 10 to rotate more smoothly.

[0070] See also Fig.13The box supply device 100 may further include a wheel 20, which may be mounted on the frame 10, for example, on the base 11 of the frame 10, and the wheel 20 helps to improve the flexibility of the frame 10 to rotate relative to the workbench 70. The wheel 20 may be a universal wheel.

[0071] The embodiment of the present application further provides a packaging device (not shown), which includes the box supply device 100 of any of the above embodiments.

[0072] In the packaging device provided in the embodiment of the present application, the box taking mechanism 30 and the box pushing mechanism 50 are installed on the frame 10 and are arranged opposite to each other. Since the box pushing mechanism 50 and the box taking mechanism 30 are suitable for accommodating the packaging box 200, the main box pushing component 51 of the box pushing mechanism 50 is suitable for pushing the packaging box 200 in the direction of the box taking mechanism 30, thereby helping to push the packaging box 200 toward the box taking mechanism 30, and the auxiliary box pushing component 53 of the box pushing mechanism 50 is suitable for pushing the first thickness portion 201 of the packaging box 200 in the direction of the box taking mechanism 30, and the thickness of the first thickness portion 201 of the packaging box 200 is less than the thickness of the second thickness portion 202. Since the box pushing mechanism 50 additionally pushes the thinner part of the packaging box 200 through the auxiliary box pushing component 53, it helps to straighten and flatten the packaging box 200, so that the first thickness portion 201 of the packaging box 200 is also as close to the box taking mechanism 30 as possible, further facilitating the box taking operation of the box taking mechanism 30 and improving the box taking success rate of the box taking mechanism 30.
