Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to a box turning transport device. Background Art

[0002] In the carton production process, the cartons usually need to be turned over before the carton binding process. The produced carton products are generally transported horizontally by conveyor belts or conveyor rollers. It is difficult to turn the cartons during the transportation process. The existing carton production lines usually use manual methods to turn the cartons, which increases labor costs. At the same time, the manual turning efficiency is slow, which in turn affects the efficiency of product packaging and reduces production efficiency.

[0003] In this regard, transport devices that can convey carton products and flip the cartons during the conveying process have gradually appeared on the market and in the patent documents that have been applied for. For example, the current Chinese patent application with publication number CN115285648A discloses a packaging box flipping roller conveyor, which includes a conveying roller for horizontally conveying packaging boxes. A flipping mechanism is arranged on the conveying path of the conveying roller. The flipping mechanism includes a rotating shaft and a plurality of flaps connected to the rotating shaft. This patent can realize a 90° flip of the carton through the cooperation of the rotating shaft and the flap during the horizontal transportation of the carton on the transmission roller.

[0004] However, due to factors such as factory layout and space limitations, there are sometimes differences in the heights of workstations between various processes in a carton production line. This requires that during the transportation of the cartons, not only the cartons need to be turned over, but also the height of the cartons need to be adjusted. The cartons need to be lifted or lowered to a workstation at a specified height and then transported to the next process. In this regard, existing carton production lines usually need to be equipped with carton transport devices with different transmission heights, as well as additional special elevators between carton transport devices with different transmission heights. Robots, telescopic cylinders and other mechanisms are used to turn and adjust the height of the cartons in steps. This not only increases the equipment investment cost, but also makes the production line more complicated and increases the size of the equipment. Summary of the invention

[0005] The present invention aims to provide a carton turning and transporting device, which can turn over and lift cartons synchronously during the process of transporting cartons, and has a high degree of integration, which is conducive to simplifying the production line and reducing production costs.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: A box-turning and transporting device comprises a box-turning mechanism and a flipping mechanism; the box-turning mechanism has a horizontal transport surface for conveying box products along a horizontal straight line direction; the box-turning mechanism has at least two groups, namely a first box-turning mechanism and a second box-turning mechanism; the second box-turning mechanism is arranged at one end of the horizontal transport surface of the first box-turning mechanism, and the horizontal transport surface of the second box-turning mechanism is arranged at a higher position relative to the horizontal transport surface of the first box-turning mechanism; the flipping mechanism is arranged between the first box-turning mechanism and the second box-turning mechanism; the flipping mechanism comprises a rotating shaft, which extends radially outward to form a connecting body, and a flipping bracket is connected to the end of the connecting body away from the rotating shaft; when the rotating shaft rotates, the flipping bracket can rotate circumferentially around the rotating shaft at intervals driven by the connecting body, thereby synchronously flipping and lifting the box products from the first box-turning mechanism to the second box-turning mechanism, or synchronously flipping and lowering the box products from the second box-turning mechanism to the first box-turning mechanism.

[0007] Furthermore, the horizontal transport surface of the first box transporting mechanism is arranged at a lower position relative to the rotation axis of the rotating shaft.

[0008] Furthermore, a movable groove is formed longitudinally through one end of the horizontal transport surface of the box transport mechanism close to the flip mechanism; when the flip bracket rotates circumferentially around the rotating shaft at intervals, it can pass through the horizontal transport surface of the box transport mechanism through the movable groove.

[0009] Furthermore, the flip bracket has two groups and is arranged on the rotating shaft laterally opposite to each other; each group of flip brackets is provided with at least one group of first positioning surfaces for abutting and supporting the bottom of the box product; the first positioning surface is vertically extended at one end close to the rotating shaft to form a second positioning surface for abutting and supporting the outer side wall of the forward end of the box product.

[0010] Furthermore, the box transport mechanism is a roller transport mechanism, which includes a frame, a plurality of first conveying roller groups horizontally rotatably connected to the frame, and a second conveying roller group rotatably positioned between two groups of flip brackets, and the first conveying roller group and the second conveying roller group are connected by belt drive.

[0011] Furthermore, the flip bracket is provided with a fixing structure for increasing the static friction force when the flip bracket and the box product are in contact with each other.

[0012] Furthermore, the fixing structure includes an anti-slip layer connected to the flip bracket.

[0013] Furthermore, a negative pressure hole is provided on the flip bracket, and the negative pressure hole is connected to an external negative pressure source for vacuum adsorption of the surface of the box product.

[0014] Furthermore, it also includes a buffer component for providing elastic buffer support to the box product after the box product is flipped over, the buffer component includes an elastic member penetrating the horizontal transport surface of the box transport mechanism, one end of the elastic member is higher than the horizontal transport surface of the box transport mechanism and is connected to a pressure plate for the bottom of the box product to abut, and the end of the elastic member away from the pressure plate is connected to the box transport mechanism.

[0015] Furthermore, the buffer assembly includes an arc-shaped telescopic rod, a fixed end of the arc-shaped telescopic rod is connected to the box transport mechanism, and a telescopic end of the arc-shaped telescopic rod is connected to the pressure plate. The elastic member is a spring and is sleeved on the arc-shaped telescopic rod.

[0016] Compared with the prior art, the advantages of the present invention are: 1. Compared with the existing box-turning transport device that can only turn over the box products during horizontal transportation, the present invention can drive the turning bracket to rotate around the rotating shaft at intervals through the rotating shaft in coordination with the connecting body and the turning bracket, so that the box products can be turned over and simultaneously lifted or lowered, that is, the height can be adjusted; 2. Compared with the existing technical solution of "providing a special elevator between two groups of carton transport devices with different transport heights, and using manipulators, telescopic cylinders and other mechanisms to flip and adjust the height of the cartons", the present application does not require step-by-step operation. The turning shaft can be rotated, and the turning bracket can be driven to rotate circumferentially around the turning shaft at intervals with the help of the connector. In the process of driving the box product to flip, the conditions for the transport height of the box product can be simultaneously completed, that is, the flipping and height adjustment of the box product can be completed at one time. The equipment has a high degree of integration, which can simplify the structure and operation process, and thus is conducive to reducing the size and footprint of the device. In addition, there is no need for multiple devices to work together during the working process, and the working stability is good. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0021] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings: Embodiment 1 refer to Figure 1~Figure 4A box-turning transport device, like the existing transport device capable of turning cartons, includes a box transport mechanism 1 and a turning mechanism 2. The box transport mechanism 1 has a horizontal transport surface 13, and the horizontal transport surface 13 is used to transport box products along a horizontal straight line. The implementation of the horizontal transport surface 13 of the box transport mechanism 1 is diverse. For example, the box transport mechanism 1 can be a conveyor belt transport mechanism, and the horizontal transport surface 13 is formed on the outer upper top surface of the conveyor belt when the conveyor belt is working. Alternatively, the box transport mechanism 1 can be a conveyor roller transport mechanism, and the horizontal transport surface 13 is a flat, discontinuous and continuous transport surface formed by a plurality of conveyor rollers arranged in a row. In addition to the above-mentioned conveyor belts and conveyor rollers, the box transport mechanism 1 can also be a chain plate conveyor mechanism or other conveying mechanism capable of horizontally transporting box products.

[0023] The improvement of the present application is that: the box turning and transporting device includes a main frame 3, the box transporting mechanism 1 has at least two groups and are respectively a first box transporting mechanism 11 and a second box transporting mechanism 12, the first box transporting mechanism 11 is installed at one end of the main frame 3, and the second box transporting mechanism 12 is installed at the other end of the main frame 3 away from the first box transporting mechanism 11, that is, it is arranged at one end of the horizontal transport surface 13 of the first box transporting mechanism 11, and the horizontal transport surface 13 of the second box transporting mechanism 12 is arranged at a higher position relative to the horizontal transport surface 13 of the first box transporting mechanism 11. The turning mechanism 2 is arranged on the main frame 3 and located between the first box transporting mechanism 11 and the second box transporting mechanism 12, and the turning mechanism 2 includes a rotating shaft 21 and a connecting body 22, the rotating shaft 21 is rotatably connected to the main frame 3, the connecting body 22 is connected to the rotating shaft 21 and extends radially outward along the rotating shaft 21 with the rotating shaft 21 as the starting point, and a turning bracket 23 for contacting the box product and driving it to move is connected to the end of the connecting body 22 radially away from the rotating shaft 21 along the radial direction of the rotating shaft 21.

[0024] Through the above technical scheme, during the transportation process of the first box transport mechanism 11 and the second box transport mechanism 12, the rotating shaft 21 can rotate relative to the main frame 3 under the drive of a driving device such as a motor. Since the connecting body 22 extends radially relative to the rotating shaft 21 and the flip bracket 23 is connected to the farther end of the radial extension of the connecting body 22, the flip bracket 23 can rotate circumferentially around the rotating shaft 21 at intervals under the drive of the connecting body 22, and then abut against and support the box product to flip the box product from the horizontal transmission surface of the first box transport mechanism 11 and synchronously lift it to the horizontal transmission surface of the second box transport mechanism 12 (when the overall horizontal transportation direction of the box product is "first box transport mechanism 11→second box transport mechanism 12"), or flip the box product from the horizontal transmission surface of the second box transport mechanism 12 and synchronously lower it to the horizontal transmission surface of the first box transport mechanism 11 (when the overall horizontal transportation direction of the box product is "second box transport mechanism 12→first box transport mechanism 11").

[0025] Compared with the "existing box-turning transport device that can only realize the flipping of box products in the horizontal transport process", the present application can drive the flip bracket 23 to rotate circumferentially around the rotating shaft 21 at intervals through the rotating shaft 21 in coordination with the connecting body 22 and the flip bracket 23, so that the box products can be flipped while the box products are being lifted or lowered synchronously, that is, the height is adjusted; and compared with the technical scheme of "the existing special lifting machine is equipped between two groups of carton transport devices with different transport heights, and the carton is flipped and the height is adjusted by means of mechanisms such as manipulators and telescopic cylinders", the present application does not need to be operated in steps, and can directly rotate through the rotating shaft 21, and drive the flip bracket 23 to rotate circumferentially around the rotating shaft 21 at intervals by means of the connecting body 22, and synchronously complete the adjustment of the transport height of the box product in the process of driving the box product to flip, that is, complete the flipping and height adjustment of the box product at one time, the equipment has a high degree of integration, can simplify the structure and operation process, and thus is conducive to reducing the size and floor space of the device, and does not require multiple devices to work together during the working process, and has good working stability and reliability.

[0026] The structural components and connection methods of the turning mechanism 2 and the box transporting mechanism 1 are described in detail below.

[0027] In order to make the device structure more compact and further reduce the size and floor space of the device, in this embodiment: the horizontal transport surface 13 of the two sets of box transport mechanisms 1 (the first box transport mechanism 11 and the second box transport mechanism 12) is longitudinally penetrated by an active groove 14 at one end close to the flip mechanism 2. Due to the provision of the active groove 14, when the flip bracket 23 rotates circumferentially around the rotating shaft 21 at intervals, it can pass through the horizontal transport surface 13 of the box transport mechanism 1 through the active groove 14, avoiding the flip mechanism 2 from needing additional horizontal space to complete the action during the flipping process, thereby reducing the overall floor space of the device. In addition, the design of the active groove 14 allows the flip bracket 23 to fit closely under or above the horizontal transport surface 13 of the box transport mechanism 1 when flipping, which can maximize the use of vertical space.

[0028] The flip bracket 23 has two groups and is laterally aligned with each other on the rotating shaft 21. Each group of flip brackets 23 is provided with at least one group of first positioning surfaces 231. The first positioning surfaces 231 extend laterally as shown in the accompanying drawings, and are used to abut against the bottom of the supporting box product during the flipping process. The first positioning surface 231 is vertically extended at one end close to the rotating shaft 21 to form a second positioning surface 232. The second positioning surface 232 is used to abut against the outer side wall of the forward end of the supporting box product, thereby providing additional support during the flipping process to prevent the box product from slipping or tilting. During operation, driven by the rotation of the rotating shaft 21 and the connecting body 22, the first positioning surfaces 231 of the two sets of laterally opposed flip brackets 23 pass through the movable groove 14 of the initial box transport mechanism 1 (the first box transport mechanism 11 or the second box transport mechanism 12) from bottom to top, and then reach the horizontal transport surface 13 of the initial box transport mechanism 1 and abut against the bottom of the supporting box product, thereby simulating the action of lifting with both hands to drive the box product to rotate circumferentially around the rotating shaft 21 at intervals, thereby synchronously flipping and lifting the box product or synchronously flipping and lowering it to the target box transport mechanism 1 (for example, when the initial box transport mechanism 1 is the first box transport mechanism 11, the target box transport mechanism 1 corresponds to the second box transport mechanism 12).

[0029] The above-mentioned "flip bracket 23 is designed as two groups, and is arranged on the rotating shaft 21 laterally opposite to each other, simulating the action of lifting with both hands to drive the box product to flip and rise and fall" solution, the two groups of flip brackets 23 have their respective first positioning surfaces 231 and second positioning surfaces 232 to support and position the bottom and sides of the box product, forming a multi-faceted contact support mode, without the need for large-area contact with the box product, which is beneficial to saving the volume of the flip mechanism 2.

[0030] In addition, to ensure that the box product can fully contact the flip bracket 23 before flipping, flipping is performed on the basis of fully contacting the flip bracket 23. In this embodiment, the box transport mechanism 1 is preferably a roller transport mechanism, which includes a frame 15, and the end of the frame 15 away from the rotating shaft 21 is rotatably provided with a first conveying roller group 16 in the horizontal direction, and the end of the frame 15 close to the rotating shaft 21 is provided with a plurality of second conveying roller groups 17, and the plurality of second conveying roller groups 17 are arranged at intervals in the vertical transmission direction. At least one of the plurality of second conveying roller groups 17 is rotatably positioned between the two groups of flip brackets 23 and connected to the first conveying roller group 16 through a belt drive. The first conveying roller group 16 and the second conveying roller group 17 cooperate to form a horizontal transport surface 13, and adjacent second conveying roller groups 17 are spaced to form the above-mentioned movable groove 14. During operation, the first conveying roller group 16 of the initial box transport mechanism 1 (the first box transport mechanism 11 or the second box transport mechanism 12) may be responsible for smoothly transferring the box product from the input end to the vicinity of the flip bracket 23, and then the second conveying roller group 17 may continue to transport the box product, so that the side wall of the forward end of the box product abuts against the second positioning surface 232 of the flip bracket 23, ensuring that the box product can fully contact the flip bracket 23 before flipping, and flip under the support of the flip bracket 23, to avoid the box product from detaching from the flip bracket 23 due to the excessively fast flipping rate during the flipping process, causing a safety accident, thereby improving the flipping stability and safety of the box product and facilitating the improvement of the flipping efficiency.

[0031] On the basis of setting the first conveying roller group 16 and the second conveying roller group 17 for two-stage transportation and ensuring that the flip bracket 23 fully contacts the flip bracket 23, in order to further enhance the stability of the box product during synchronous flipping and lifting, in this embodiment, a fixed structure 24 is provided on the flip bracket 23. The fixed structure 24 increases the static friction between the box product and the flip bracket 23, thereby preventing the box product from detaching from the flip bracket 23 during movement or deviating from the position relative to the flip bracket 23. While improving the flipping stability, it can ensure that the landing position of the box product when flipped and lifted to the target box transport mechanism 1 tends to be consistent, thereby improving the transmission accuracy.

[0032] The implementation methods of the fixed structure 24 are diverse. For example, in this embodiment, the fixed structure 24 is an anti-skid layer 241 disposed on the first positioning surface 231 and the second positioning surface 232. The anti-skid layer 241 can be made of materials with high friction coefficient and wear resistance, such as rubber, polyurethane, PVC, etc. These materials can not only effectively increase the friction between the box product and prevent it from sliding or deflecting, but also have good durability and anti-aging performance. In addition, the surface of the anti-skid layer 241 can be designed into various shapes and textures, such as convex points, grooves, grids or diamonds, etc. These structural forms can further increase the contact area, improve the friction, and help maintain the stability of the box product during the flipping process. The anti-skid layer 241 can be fixed on the first positioning surface 231 and the second positioning surface 232 by pasting, spraying, injection molding, etc. The specific installation method selected depends on the material and thickness of the anti-skid layer 241 and the material and structure of the flip bracket 23.

[0033] In addition to the anti-slip layer 241, the fixed structure 24 can also be provided with a plurality of negative pressure holes 242 on the first positioning surface 231 and the second positioning surface 232 of the flip bracket 23. The negative pressure holes 242 are connected to a negative pressure device such as an air pump. When the box product contacts the flip bracket 23, a negative pressure area can be formed at the opening of the negative pressure hole 242 under the action of the negative pressure device, and the box product can be tightly adsorbed on the flip bracket 23, thereby increasing the contact force between the box product and the flip bracket 23, increasing the static friction between the two, and improving the stability of the box product during the flipping process. In addition, by providing a negative pressure port to adsorb and fix the box product, wear and noise caused by friction can also be reduced.

[0034] It should be noted that the anti-skid layer 241 and the negative pressure hole 242 of the above-mentioned fixing structure 24 can be implemented separately or used in conjunction with each other, that is, the anti-skid layer 241 and the negative pressure hole 242 are simultaneously provided on the flip bracket 23, the anti-skid layer 241 is provided on the first positioning surface 231 and the second positioning surface 232 and is preferably made of elastic materials such as silicone and rubber, the negative pressure hole 242 is provided on the first positioning surface 231 and the second positioning surface 232, and the negative pressure hole 242 penetrates the anti-skid layer 241. When working, the anti-skid layer 241 made of elastic material has good elasticity and adaptability, can closely fit the surface of the box product, fill the small gap between the box product and the flip bracket 23, and then form an effective sealing environment, which is crucial for negative pressure adsorption, because it can prevent air from leaking from the gap, improve the airtightness of the negative pressure hole 242 for negative pressure adsorption of the box product, thereby ensuring that sufficient negative pressure can be generated in the negative pressure hole 242 to fix the box product and improve the stability of negative pressure adsorption.

[0035] The connecting body 22 is a plate-like structure, the rotating shaft 21 is integrally connected with the rotating block 25 and a connecting plate is axially penetrated, the connecting plate is detachably connected to the rotating block 25 by fasteners such as screws and latches, and the flip bracket 23 is detachably connected to the connecting body 22 by fasteners such as screws and latches. It is convenient for later maintenance and replacement, and it is also convenient to replace the flip bracket 23 of different specifications to meet the flip requirements of different box products.

[0036] Furthermore, in this embodiment, the box-turning transport device further includes a buffer assembly 4 for elastically buffering and supporting the box product after the box product is turned over. The buffer assembly 4 includes an elastic member 41 penetrating the horizontal transport surface 13 of the target box transport mechanism 1 (when the box product is turned over and lifted from the first box transport mechanism 11 to the second box transport mechanism 12, the second box transport mechanism 12 is the target box transport mechanism 1), one end of the elastic member 41 is higher than the horizontal transport surface 13 of the box transport mechanism 1 and is connected to a pressing plate 42 for the bottom of the box product to abut against, and one end of the elastic member 41 away from the pressing plate 42 is connected to the box transport mechanism 1. When the box product turns over and falls on the pressing plate 42, the elastic member 41 will deform, absorb part of the impact energy to protect the box product from damage, and support the box product through its elastic restoring force. The elastic member 41 may be made of a spring, rubber, air cushion or other structure, and the pressure plate 42 may be made of an elastic material and have a smooth surface. The pressure plate 42 is made of an elastic material and can further play a buffering role when contacting the box product to avoid damage to the surface of the box product. The smooth surface of the pressure plate 42 is to reduce the friction between the pressure plate 42 and the box product, making it easier for the pressure plate 42 to detach from the surface of the box product after providing buffering support for the box product.

[0037] Specifically, the buffer assembly 4 includes an arc-shaped telescopic rod 43, the fixed end of which is connected to the box transport mechanism 1, and the telescopic end of which is connected to the pressure plate 42, and the elastic member 41 is a spring and is sleeved on the arc-shaped telescopic rod 43. The shape of the arc-shaped telescopic rod 43 is designed to be an arc, which helps to better adapt to the flipping trajectory of the box product and reduce friction and resistance during the flipping process.

[0038] Furthermore, in order to increase the height of the box product to be turned and lifted by the flip bracket 23, in this embodiment, the horizontal transport surface 13 of the first box transport mechanism 11 is arranged at a low position relative to the axis 21 line of the rotating shaft 21. In the attached figure, the rotating shaft 21 is arranged between the horizontal transport surfaces 13 of the first box transport mechanism 11 and the second box transport mechanism 12. In the box flipping and transporting device, the turning and lifting height refers to the height change of the box product relative to the initial position during the turning process. By adjusting the relative position between the horizontal transport surface 13 of the first box transport mechanism 11 and the axis 21 line of the rotating shaft 21, the turning height can be significantly affected. In this embodiment, the horizontal transport surface 13 of the first box transport mechanism 11 is arranged below the axis of the rotating shaft 21, so that the box product is in a lower position at the beginning of the turning. When the rotating shaft 21 rotates, the box product will rise along the predetermined turning trajectory until it reaches the highest point. When the length of the connecting body 22 is constant, due to the low starting position, the box product will experience a greater height change during the turning process, thereby increasing the turning and lifting height.

[0039] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are all covered by the patent scope of the present invention.
