Description

Technical Field

[0001] The utility model relates to the field of material transportation, in particular to a turnover box transportation buffer device. Background Art

[0002] The transportation of turnover boxes 50 can be used in the transportation, distribution, storage, circulation processing and other links in factory logistics, and can centrally summarize parts to avoid parts being missed or placed unevenly during transportation;

[0003] During the transportation of the turnover boxes 50, on the one hand, it is easy to cause transportation congestion due to insufficient transportation speed or equipment downtime, and on the other hand, the scheduling of the turnover boxes 50 is not reasonable, which wastes transportation resources. For example, the transportation speed of the turnover boxes 50 does not match the entire production line, or there is a time delay between the transportation of the turnover boxes 50 and the next process. When the turnover boxes 50 are transported to the transition position, the turnover boxes 50 need to wait due to the speed difference. At this time, the number of turnover boxes 50 will be too large and there is a lack of corresponding buffer.

[0004] On the other hand, some devices that can cache turnover boxes 50 use pallets 65 to lift the turnover boxes 50 to stagger the transportation to achieve caching of the turnover boxes 50. However, there is a problem: the single-sided pallet 65 can easily cause instability in the lifting process of the turnover box 50, and it is easy to cause tilting and tipping problems. Although the double-sided pallet 65 can ensure the stability of the turnover box 50, it cannot be adjusted according to the width of the turnover box 50, and the lifting and lifting at the same time require sensors and controllers to ensure joint control. Summary of the Invention

[0005] The purpose of the utility model is to provide a turnover box conveying and caching device, which not only realizes the caching of turnover boxes and avoids squeezing caused by the accumulation of multiple turnover boxes without affecting the conveying of turnover boxes, but also can adjust the distance between adjacent pallets in the horizontal direction to make it suitable for turnover boxes of different widths, and the caching is more stable.

[0006] To achieve the above purpose, this turnkey box conveying and buffering device includes:

[0007] The frame body is equipped with a conveying component for longitudinal movement of the turnover box;

[0008] A mobile frame is driven to move laterally and is located on the frame body;

[0009] A pair of lifting components are respectively mounted on the frame body and the movable frame and are located on both sides of the conveying component; each set of lifting components includes:

[0010] The support plate moves upward relative to the frame body and the movable frame;

[0011] Among them, the lateral width of the turnover box is greater than the lateral width of the conveying component; the laterally adjacent pallets move synchronously at the same height and can lift the turnover box from the bottom.

[0012] In some examples of the present invention, the lifting component further includes:

[0013] A pair of first shafts are arranged one above the other, with at least one first guide wheel fixed on each first shaft;

[0014] The first transmission belt is wound around the outer sides of the upper and lower adjacent first guide wheels and transmits the power;

[0015] There are multiple supporting plates, which are connected to the first conveyor belt at intervals;

[0016] One of the first shafts in each group of lifting components is connected to the drive motor; or one of the first shafts in one of the lifting components is connected to the drive motor, and a pair of laterally adjacent first shafts are connected via a linkage component.

[0017] In some examples of the present invention, the linkage component includes:

[0018] A second guide wheel is fixedly connected to the first shaft having the driving motor;

[0019] a fifth guide wheel, fixedly connected to another laterally adjacent first shaft;

[0020] Among them, power is transmitted between the second guide wheel and the fifth guide wheel through the second transmission belt.

[0021] In some examples of the present invention, the linkage component further includes

[0022] a second shaft connected to the fixed plate;

[0023] The third guide wheel and the fourth guide wheel are coaxially fixed on the second shaft; the third guide wheel is meshed and connected with the second guide wheel, and the fourth guide wheel is connected with the fifth guide wheel through a second transmission belt wound around the outside thereof.

[0024] In some examples of the present invention, the fixing plate is provided with an arc-shaped groove with the axis of the second guide wheel as the center;

[0025] The second shaft is slidably positioned in the arc groove and is locked and fixed.

[0026] In some examples of the present invention, the support plate is mounted on the first conveyor belt via a fixing block;

[0027] A vertically arranged first support plate is provided on the frame body and the movable frame;

[0028] The first support plate is located on the inner side of the first conveyor belt close to the conveying component. When the first conveyor belt is driven to rotate, the fixed block supporting one side of the turnover box contacts the first support plate.

[0029] In some examples of the present invention, the support plate is an L-shaped structure, with one side contacting the bottom of the turnover box to lift it, and the other side contacting the lateral side of the turnover box to limit it.

[0030] In some examples of the present invention, an adjustment component is provided on the frame body;

[0031] The adjusting component comprises:

[0032] The screw rod is arranged horizontally and is threadedly connected to the mobile frame, with one end driving the rotation;

[0033] At least one guide rod is arranged transversely and connected to the movable frame in a relatively sliding manner.

[0034] Compared with the existing technology, this turnover box conveying and caching device is provided with lifting components on the mobile frame and the frame body respectively. The transversely adjacent pallets synchronously lift the turnover boxes, thereby caching the turnover boxes without affecting the transportation of the turnover boxes, avoiding squeezing caused by the accumulation of multiple turnover boxes, and more stably lifting the turnover boxes, avoiding shaking and tilting of the turnover boxes caused by unilateral lifting. By moving the mobile frame laterally closer to or away from the conveying components, the distance between the transversely adjacent pallets can be adjusted, making it suitable for turnover boxes of different widths.

[0035] Since the lifting component also includes a pair of first shafts and a first conveyor belt, the first conveyor belt is rotated by the first shafts arranged up and down and the first guide wheel fixed on the first shaft. On the one hand, it can flexibly lift the turnover box upward for buffering and place the turnover box downward for transportation. On the other hand, it can adjust the size of the pallet based on the use environment and be suitable for different use environments.

[0036] Since the fixed plate in the linkage component is provided with an arcuate groove with the axis of the second guide wheel as the center, the second shaft slides to a suitable position in the arcuate groove and is locked, so that the second conveyor belt can be adjusted in angle to meet the movement of the movable frame while the length remains unchanged. This can realize the linkage of a pair of lifting components under a single power input, avoiding the frequent replacement of the second conveyor belt or the need to match second conveyor belts of different lengths. In addition, the linkage component can avoid the structural complexity caused by the use of sensor recognition and controller for separate control, making the overall structure simpler.

[0037] When the first conveyor belt is driven to rotate, the fixed block supporting one side of the turnover box contacts the first support plate. Through the contact between the first support plate and the fixed block, on the one hand, the first support plate can tension the first conveyor belt to a certain extent to ensure the stability of the first conveyor belt during the rotation process. On the other hand, the first support plate can guide the fixed block to prevent the fixed block from shifting due to uneven force on the turnover box. In addition, the L-shaped structure support plate can not only support and lift the bottom of the turnover box, but also clamp and limit the turnover box to avoid shaking due to a gap between the turnover box and the support plate.

[0054] like Figures 1 to 4 As shown, this turntable transport buffer device includes:

[0055] The frame body 10 is provided with a conveying component 40 for longitudinally moving the turnover box 50;

[0056] The mobile frame 20 is driven to move laterally and is located on the frame body 10;

[0057] A pair of lifting components are mounted on the frame body 10 and the movable frame 20, respectively, and are located on both sides of the conveying component 40; each set of lifting components includes:

[0058] The support plate 65 moves upward relative to the frame body 10 and the movable frame 20;

[0059] The lateral width of the turnover box 50 is greater than the lateral width of the conveying member 40; the lateral adjacent pallets 65 move synchronously at the same height and are capable of lifting the turnover box 50 from below;

[0060] Specifically, the frame body 10 is an integral support structure, and can be formed by welding or bolting a rectangular tube to form a frame body; the conveying component 40 is a plurality of rollers rotating in the same direction, and is located between the mobile frame 20 and one side of the frame body 10; the width of the rollers is smaller than the width of the turnover box 50, so that the support plate 65 can act on the peripheral side of the turnover box 50. The conveying component 40 is a traditional conveying structure for conveying the turnover box 50, which will not be further explained here;

[0061] The movable frame 20 moves laterally toward or away from the conveying member 40, which may also be a frame structure;

[0062] A pair of lifting members are located on both sides of the conveying member 40, wherein the pallets 65 can lift the turnover box 50 upward from the bottom, so that the turnover box 50 is separated from the conveying member 40 for buffering; accordingly, the pallets 65 adjacent to each other in the horizontal direction move synchronously to ensure that the turnover box 50 is stably lifted at the same time; each set of lifting members may include multiple pallets 65, which are arranged at intervals and the height of the pallets 65 adjacent to each other is greater than the height of the turnover box 50;

[0063] When the turnover box conveying and buffering device is initially used, the pallets 65 are no higher than the conveying member 40, or the spacing between the multiple pallets 65 is greater than the height of the turnover box 50, so that the turnover box 50 can normally pass between the upper and lower adjacent pallets 65 to avoid corresponding interference; based on the pallets 65 in the holding member on the frame body 10, the position of the mobile frame 20 is adjusted according to the lateral width of the turnover box 50, that is, the mobile frame 20 is driven to move closer to the turnover box 50 so that its holding member is close to the holding member on the frame body 10;

[0064] When the turnover box 50 is not in use for buffering, the turnover box 50 is normally transported longitudinally on the transport component 40 and does not come into contact with the frame body 10, the moving frame 20, and the lifting component.

[0065] When a large number of turnover boxes 50 are blocked and need to be buffered, the pallets 65 adjacent to each other in the horizontal direction move upward synchronously so that the pallets 65 can synchronously support the lower ends of the turnover boxes 50. When the pallets 65 move upward to a certain height, this height can ensure that the next turnover box 50 can pass normally on the conveying component 40. When each group of supporting components includes multiple pallets 65, the pallets 65 of the first layer are higher than the turnover boxes 50, completing the support and buffering of the turnover boxes 50, and the pallets 65 of the second layer are slightly lower than the turnover boxes 50, waiting for the buffering of the next turnover box 50.

[0066] This turnover box conveying and caching device is configured with lifting components on the mobile frame 20 and the frame body 10 respectively, so that the laterally adjacent pallets 65 lift the turnover boxes 50 synchronously, thereby caching the turnover boxes 50 without affecting the conveying of the turnover boxes 50, avoiding squeezing caused by the accumulation of multiple turnover boxes 50, and making the lifting of the turnover boxes 50 more stable, avoiding shaking and tilting of the turnover boxes 50 caused by unilateral lifting; by moving the mobile frame 20 laterally close to or away from the conveying component 40, the distance between the laterally adjacent pallets 65 can be adjusted to make it suitable for turnover boxes 50 of different widths.

[0067] In some examples of the present invention, Figure 2 、 Figure 3 、 Figure 4 As shown, the lifting component also includes:

[0068] A pair of first shafts 62 are arranged one above the other, and at least one first guide wheel 63 is fixed to each first shaft 62;

[0069] The first transmission belt 64 is wound around the outer sides of the upper and lower adjacent first guide wheels 63 and transmits the power;

[0070] There are multiple supporting plates 65, which are connected to the first conveyor belt 64 at intervals;

[0071] One of the first shafts 62 in each set of lifting components is connected to the drive motor 61; or one of the first shafts 62 in one of the lifting components is connected to the drive motor 61, and a pair of laterally adjacent first shafts 62 are connected via a linkage component 70;

[0072] Specifically, the axis of the first shaft 62 is arranged longitudinally and is rotatably mounted on the frame body 10 / movable frame 20 via a bearing seat;

[0073] When one of the first shafts 62 in each set of lifting components is connected to the drive motor 61, the pair of drive motors 61 are connected to the controller, and the controller controls the start and stop of the drive motors 61 so that the first conveyor belt 64 rotates at the same speed and in the same direction. Preferably, the drive motor 61 is a servo motor.

[0074] After the driving motor 61 is started, the first conveyor belt 64 is rotated through the first shaft 62 arranged up and down and the first guide wheel 63 fixed on the first shaft 62. Preferably, there are two first guide wheels 63, which are longitudinally arranged on the first shaft 62.

[0075] In this example, the first conveyor belt 64 is rotated so that the pallets 65 thereon can move in a circular cycle. On the one hand, the turnover boxes 50 can be flexibly lifted up for caching and placed down for transportation. On the other hand, the size of the pallets 65 can be adjusted based on the usage environment. For example, there are 10 pallets 65 on the first conveyor belt 64, of which the pallets 65 spaced apart from each other are of size A, and the other pallets 65 spaced apart from each other are of size B. The forward and reverse rotation of the first conveyor belt 64 can enable 5 pallets 65 of size A to cache and transport 5 corresponding turnover boxes 50. When the size of the turnover boxes 50 changes, the first conveyor belt 64 rotates half a cycle, so that the other 5 pallets 65 of size B can cache and transport the 5 corresponding turnover boxes 50. Therefore, it is more flexible and suitable for different usage environments.

[0076] In some examples of the present invention, Figure 2 、 Figure 3 As shown, when a first shaft 62 of one of the lifting components is connected to the drive motor 61, and a pair of laterally adjacent first shafts 62 are connected by a linkage component 70, the linkage component 70 includes:

[0077] The second guide wheel 71 is fixedly connected to the first shaft 62 with the driving motor 61;

[0078] A fifth guide wheel 75 is fixedly connected to another laterally adjacent first shaft 62;

[0079] The second guide wheel 71 and the fifth guide wheel 75 transmit power via the second transmission belt 74.

[0080] Specifically, the drive motor 61 is started, and the first conveyor belt 64 is moved through the first shaft 62 arranged vertically in the supporting component and the first guide wheel 63 fixed to the first shaft 62. The first shaft 62 drives the second guide wheel 71 to rotate, and drives the fifth guide wheel 75 through the second conveyor belt 74, thereby rotating the other first shaft 62 horizontally. That is, the other supporting component has the same power source, driving the corresponding first conveyor belt 64 to move.

[0081] In this example, a single drive motor 61 is used as the input of the power source to link the pair of lifting components via the linkage component 70. This linkage means that the first conveyor belts 64 in the pair of lifting components move synchronously, avoiding the structural complexity caused by using sensor recognition and controllers for separate control, making the overall structure simpler.

[0082] In some examples of the present invention, such as Figure 3 As shown, the linkage component 70 also includes

[0083] The second shaft 76 is connected to the fixed plate 80;

[0084] The third guide wheel 72 and the fourth guide wheel 73 are coaxially fixed on the second shaft 76; the third guide wheel 72 is meshed with the second guide wheel 71, and the fourth guide wheel 73 is connected to the fifth guide wheel 75 via a second transmission belt 74 wound around the outside of the third guide wheel 72;

[0085] Specifically, after the first shaft 62 on one side drives the second guide wheel 71 to rotate, the power is sequentially transmitted through the third guide wheel 72, the fourth guide wheel 73 coaxially connected to the third guide wheel 72, the second transmission belt 74 and the fifth guide wheel 75, and finally the fifth guide wheel 75 drives the first shaft 62 on the other side adjacent to the first shaft 62 to rotate, thereby achieving the synchronous action of the pair of lifting components.

[0086] However, a problem with the linkage member 70 is that when the movable frame 20 moves to adjust to accommodate turnover boxes 50 of different widths, the distance between the laterally adjacent first shafts 62 also changes. At this time, in order to ensure the synchronous linkage of the pair of lifting members, the linkage member 70 also needs to be adjusted. Obviously, replacing the second conveyor belt 74 of different lengths cannot meet the usage requirements.

[0087] Therefore, in some examples of the present invention, Figure 3 、 Figure 5 、 Figure 6 As shown, the fixing plate 80 is provided with an arc-shaped groove 81 with the axis of the second guide wheel 71 as the center;

[0088] The second shaft 76 is slidably positioned in the arc-shaped groove 81 and is locked and fixed.

[0089] Specifically, the second shaft 76 can be locked and fixed by a nut, that is, the shoulder of the second shaft 76 presses against one side of the fixing plate 80, and the nut is threaded on the second shaft 76 and presses against the other side of the fixing plate 80;

[0090] like Figure 6 As shown, when the moving frame 20 moves laterally by a distance d, the second shaft 76 is moved to a position in the arcuate slot 81, so that the moving distance d of the moving frame 20 is compensated by adjusting the angle while the length of the second conveyor belt 74 remains unchanged. That is, the second shaft 76 slides in the arcuate slot 81, so that the second conveyor belt 74 is in a taut transmission state, and then is locked and fixed by a nut.

[0091] As explained, the arc-shaped groove 81 is centered on the axis of the second guide wheel 71 , and its purpose is to ensure that the third guide wheel 72 on the second shaft 76 always remains in meshing with the second guide wheel 71 on the first shaft 62 while the second shaft 76 slides, thereby meeting the power input requirements;

[0092] In this example, the second shaft 76 slides to a suitable position in the arc groove 81 and is locked, so that the second conveyor belt 74 can meet the movement of the movable frame 20 by adjusting the angle without changing the length. This can realize the linkage of a pair of lifting components with a single power input, avoiding the frequent replacement of the second conveyor belt 74 or the need to match second conveyor belts 74 of different lengths.

[0093] In some examples of the present invention, such as Figure 2 、 Figure 3 、 Figure 4 As shown, the support plate 65 is mounted on the first conveyor belt 64 through a fixing block 66;

[0094] A vertically arranged first support plate 67 is provided on the frame body 10 and the mobile frame 20;

[0095] The first support plate 67 is located on the inner side of the first conveyor belt 64 near the conveying member 40. When the first conveyor belt 64 is driven to rotate, the fixed block 66 holding up one side of the turnover box 50 contacts the first support plate 67.

[0096] Specifically, the first support plate 67 can be fixed to the frame body 10 and the mobile frame 20 through the second support plate 68. The first support plate 67 is arranged vertically to ensure that it can contact the fixed blocks 66 corresponding to the multiple support plates 65;

[0097] When multiple turnover boxes 50 are cached, a longer first conveyor belt 64 is required. When the multiple pallets 65 on the first conveyor belt 64 lift the turnover boxes 50, the first conveyor belt 64 is easily shaken because it is in a non-tensioned state.

[0098] In this example, the first support plate 67 contacts the fixed block 66 to ensure the stability of the first conveyor belt 64 during the rotation process. That is, when the support plate 65 lifts the turnover box 50, the fixed block 66 at the connection of the support plate 65 can move upward tightly against the first support plate 67. On the one hand, the first support plate 67 can tension the first conveyor belt 64 to a certain extent. On the other hand, the first support plate 67 can guide the fixed block 66 to prevent the fixed block 66 from being offset due to uneven force on the turnover box 50.

[0099] In some examples of the present invention, such as Figure 2 、 Figure 3 As shown, the support plate 65 is an L-shaped structure, one side of which contacts the bottom of the turnover box 50 to lift it, and the other side contacts the lateral side of the turnover box 50 to limit it;

[0100] Specifically, the L-shaped structure pallet 65 can not only support and lift the bottom of the turnover box 50, but also limit the turnover box 50. That is, under the initial adjustment of the movable frame 20, when the laterally adjacent pallets 65 lift the turnover box 50 from bottom to top, the two side ends of the pallet 65 can "clamp" the turnover box 50 to a certain extent. This "clamping" can ensure the stability of the turnover box 50 during the upward movement and caching process, and avoid shaking due to the gap between the turnover box 50 and the pallet 65.

[0101] In some examples of the present invention, Figure 1 、 Figure 2 As shown, the frame body 10 is provided with an adjustment component;

[0102] The adjusting component comprises:

[0103] The screw rod 32 is arranged horizontally and is threadedly connected to the movable frame 20, with one end driving the rotation;

[0104] At least one guide rod 33 is arranged transversely and is connected to the moving frame 20 for relative sliding.

[0105] Specifically, one end of the screw rod 32 can be connected to the handle 31, that is, the screw rod 32 can be manually rotated through the handle 31, and the end side of the screw rod 32 can be mounted on the frame body 10 through a bearing, so that the moving frame 20 spirally connected to the screw rod 32 will move laterally;

[0106] Both ends of the guide rod 33 are connected to the frame body 10 and can be connected to the moving frame 20 by using a sleeve or a linear bearing.

[0107] The above describes in detail an exemplary implementation of the turnover box conveying and caching device proposed in the present invention with reference to the preferred embodiments. However, those skilled in the art will understand that, without departing from the concept of the present invention, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention can be combined in various ways without exceeding the scope of protection of the present invention, which is determined by the appended claims.
