Description

Technical Field

[0001] This utility model relates to the field of transfer and transportation device technology, specifically to a transmission module with a simpler structure and lower assembly difficulty, and a transfer machine equipped with the transmission module. Background Technology

[0002] A transfer machine is a common transport device in a transmission system. After passing through the transfer machine, the original direction of travel of the relevant items can be changed. In this way, the transfer machine can realize the connection between multiple conveyor lines.

[0003] For example, patent application number 202323631062.6 discloses a lifting and transferring machine, which includes a lifting part including a lifting motor connected to a lifting assembly; a transferring part disposed above the lifting assembly, including a transferring motor and a belt transferring assembly, the transferring motor being connected to the belt transferring assembly to drive the belt transferring assembly to move; and a roller conveying part disposed above the transferring part, including a plurality of conveying rollers driven by a conveying motor; the conveying direction of the conveying rollers intersects with the conveying direction of the belt transferring assembly.

[0004] The transfer unit used in existing transfer machines is composed of components such as transfer belts, transfer drive rollers, and active transfer pulleys. In this structure, in order to realize the cyclic operation of the transfer belt and transport the carried items, it is necessary to ensure that the transfer belt is in close contact with the transfer drive rollers, active transfer pulleys, and other components, so as to achieve the transmission effect by utilizing the friction between the components. Usually, a tensioning wheel or other structure is also required to achieve the above effect.

[0005] On the one hand, the aforementioned structure necessitates the cooperation of numerous components to achieve its full functionality, increasing the overall volume of the transfer unit, particularly its height. This results in a larger overall height for the transfer machine, making it unsuitable for work environments with limited vertical space. On the other hand, during transportation, the friction caused by the tight contact between the transfer belt and the transfer drive rollers leads to significant power loss in the motor output. This power loss is further amplified when the belt hardens due to lower ambient temperatures. Utility Model Content

[0006] One of the objectives of this invention is to provide a transmission module with a simpler structure and lower power loss in motor output.

[0007] The second objective of this invention is to provide a transfer machine equipped with the aforementioned transmission module, thereby maintaining a smaller overall height and size.

[0008] This utility model is achieved through the following technical solution: A transmission module includes a main frame, several sets of transmission kits mounted on the main frame, and a transmission part connecting the several sets of transmission kits, wherein the transmission directions of the several sets of transmission kits are consistent; each transmission kit includes at least a base, at least two sets of transmission gears mounted on the base, a transport ring belt fitted around and meshing with the transmission gears, and a support part, wherein the support part is disposed between two adjacent sets of transmission gears to support the transport ring belt placed between them, such that the outer wall surface of the supported portion of the transport ring belt constitutes a transport surface; at least one set of transmission kits also includes a drive gear, and the transport ring belt is also fitted around the drive gear, with the drive gear meshing with the transport ring belt.

[0009] As a further improvement of this utility model, the transmission part includes at least one transmission rod, which is connected to the transmission gears on at least two adjacent sets of transmission kits.

[0010] As a further improvement of this utility model, the transmission part includes a transmission rod, and several sets of transmission gears placed on the same side are all mounted on the transmission rod.

[0011] As a further improvement of this utility model, the transmission kit also includes a tensioning part.

[0012] As a further improvement of this utility model, the same set of transmission kits includes two sets of transmission gears placed at both ends of the transport belt; the tensioning part includes at least one set of telescopic kits; wherein, one end of the telescopic kit is fixed to the base, and the other end is fixed to the transmission gears placed at the ends of the transport belt, so as to control the distance between the two sets of transmission gears placed at both ends of the transport belt.

[0013] As a further improvement of this utility model, the tensioning part includes at least one set of adjustable tensioning wheels. The adjustable tensioning wheels are movably mounted on the base and placed between two adjacent sets of transmission gears. At the same time, the adjustable tensioning wheels abut against the transport ring belt to force the transport ring belt to mesh with the drive gear.

[0014] As a further improvement of this utility model, the tensioning part includes at least one set of drive tensioning wheels, which are placed between the drive gear and the transmission gear. The drive tensioning wheels abut against the transport belt to force the transport belt to mesh with the drive gear.

[0015] As a further improvement of this utility model, the supporting part includes a supporting plate and a guide block disposed on the supporting plate. The supporting plate has a supporting surface that contacts the inner wall surface of the transport ring belt. The guide block is disposed on both sides of the supporting surface to form a supporting space for accommodating the transport ring belt.

[0016] As a further improvement of this utility model, a limited height is formed between the top of the guide block and the supporting surface; when the transmission kit is not carrying an item, a first working height is formed between the inner wall surface of the transport belt and the supporting surface; when the transmission kit is carrying an item, a second working height is formed between the transport surface formed by the outer wall surface of the transport belt and the supporting surface; the limited height is placed between the first working height and the second working height.

[0017] As a further improvement of this utility model, the supporting part includes several sets of supporting wheels, and each set of supporting wheels has a supporting area that contacts the transport belt. Several sets of supporting areas jointly support the transport belt to ensure the formation of the transport surface.

[0018] As a further improvement of this utility model, several sets of transmission kits without drive gears are arranged on both sides of the transmission kit containing drive gears.

[0019] Secondly, this utility model provides a transfer machine, which includes a lifting base, any of the above-mentioned transmission modules installed on the lifting base, and a first transmission section, wherein the first transmission section includes a plurality of first transmission components, and a working channel is formed between two adjacent sets of first transmission components to accommodate the transmission kit in the transmission module to lift and pass through; a first angle is formed between the transmission direction of the first transmission section and the transmission direction of the transmission module.

[0020] The beneficial effects of this utility model include: The system employs a structure that combines transmission gears with a transport belt. In its simplest form, only two sets of transmission gears are needed, positioned on either side of the inner ring of the transport belt. This achieves the meshing between the transmission gears and the transport belt, ensuring the normal cyclical movement of the transport belt within the transmission kit. A transmission surface is formed in the space between and above the two sets of transmission gears, allowing items mounted on the transmission surface to move with the transport belt to achieve the desired transport effect. This structure simplifies the transmission module, facilitating its disassembly, repair, and maintenance. The transmission kit of this utility model utilizes the meshing between the transmission gear and the transport belt to achieve transmission between the two. Compared with the prior art, this structure does not require the transport belt to maintain a large tension for a long time. It only needs to ensure that there is no skipping of teeth after the two mesh, so that the transmission can be carried out normally. The tension requirement of the transport belt is low, which also reduces the tension loss between the transport belt and the transmission gear. The power loss of the motor that drives the transport belt in the transmission module to circulate is also reduced due to overcoming the tension loss. Several sets of transmission kits can be connected by a transmission unit to achieve a transmission effect, thereby driving adjacent transmission kits to operate synchronously. This allows the entire transmission module to have at least one set of transmission kits actively driven by a drive gear, while the number of other driven transmission kits can be increased or decreased according to the user's actual needs. Compared to the existing technology where each set of transfer belts on multiple transfer units needs to be fitted onto the active transfer pulley, the structure of this utility model mainly involves the loading and unloading of the transmission kits on the main frame and the transmission unit when adding or removing driven transmission kits. This greatly reduces the difficulty of installation and facilitates the rapid deployment of production line adjustments and other tasks for the user. Compared to existing technologies, the transmission kit of this utility model, in its simplest structure, only requires two sets of transmission gears placed on both sides of the inner ring of the transport belt. This results in a smaller overall size of the transmission module, especially its height. Consequently, the height of the transfer machine equipped with this transmission module can be reduced to suit workspaces with limited height. At the same time, the fewer parts used in the transmission kit also make the overall weight of the transmission module lighter, which reduces the power required by the lifting module in the transfer machine, thereby reducing the overall power consumption of the transfer machine.

[0022] in Figure 1 and Figure 10 To clearly illustrate some of the structures, the transport rings in some of the transmission kits have been omitted; this modification does not affect the scope of protection of the claims. Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Example 1:

[0025] This embodiment provides a transmission module, such as Figure 1 As shown, the transmission module includes a main frame 1, six sets of transmission kits 2 mounted on the main frame 1, and a transmission part 3 connecting the six sets of transmission kits 2. The transmission directions of the six sets of transmission kits 2 are consistent, so as to jointly constitute the overall transmission direction of the transmission module.

[0026] like Figure 2 As shown, the transmission kit 2 includes a base 201, two sets of transmission gears 202 mounted on the base 201, a transport ring belt 203 fitted around and meshing with the transmission gears 202, and a support portion 204. In this structure, the inner wall of the transport ring belt 203 has toothed surfaces that mesh with the toothed surfaces of the transmission gears 202. Since there are only two sets of transmission gears 202 in this embodiment, they are positioned far apart at both ends of the transport ring belt 203 to create a slight tension on the belt, thus ensuring the meshing between the transmission gears 202 and the transport ring belt 203 and ensuring smooth transmission. This also causes the transport ring belt 203 positioned above them to form the initial shape of the transport surface 203-1. In this structure, the support portion 204 is positioned between the two sets of transmission gears 202 to support the transport ring belt 203 positioned between them. Figure 2Taking the perspective of the transmission kit 2 as an example, the support part 204 provides support for the transport belt 203 located between the two sets of transmission gears 202 and above, so that during the operation of the transmission kit 2, when the transport belt 203 is transported to the area within the above range, it can be supported by the support part 204. After the prototype of the transport surface 203-1 formed by the outer wall surface of the transport belt 203 is supported, a flat and complete transport surface 203-1 is formed, which can support the transported items and drive the items to move with the cyclical movement of the transport belt 203.

[0027] like Figure 3 As shown, in the six sets of transmission kits 2, one set of transmission kits 2 also includes a drive gear 205. When the transport belt 203 is installed, it is also fitted onto the drive gear 205, and the drive gear 205 meshes with the transport belt 203. In this structure, in this set of transmission kits 2, the drive gear 205 first rotates, thereby driving the transport belt 203 to circulate. During the movement of the transport belt 203, it drives the transmission gear 202 to rotate. Secondly, the active transmission kit 2 containing the drive gear 205 can drive the transmission gear 202 on the adjacent transmission kit 2 to rotate through the transmission part 3, thereby driving the transport belt 203 to move. Finally, the driven transmission kit 2 then drives the remaining adjacent transmission kits 2 to operate through the transmission part 3, thus driving all the transmission kits 2 to be put into transportation work.

[0028] Preferably, the transmission unit 3 can achieve the transmission connection between the transmission kits 2 through the transmission rods 301. Specifically, by connecting the transmission rods 301 with the transmission gears 202 located on the same side of two adjacent sets of transmission kits 2, the synchronous transmission of the two sets of transmission gears 202 can be achieved, thereby driving the synchronous operation of the two adjacent sets of transmission kits 2. For example, the transmission unit 3 in this embodiment uses five transmission rods 301. Each transmission rod 301 is connected to the adjacent transmission gears 202 only at its two ends. Therefore, on the same set of transmission kits 2, the transmission gears 202 on both sides can be respectively equipped with transmission rods 301 to drive the adjacent transmission kits 2 to operate synchronously. This structure facilitates the increase or decrease of the number of transmission kits 2 in the transmission module. For example, when it is necessary to add a set of transmission kits 2, the transmission rods 301 between the transmission kit 2 and the adjacent transmission kit 2 can be installed after the transmission kit 2 is installed on the main frame 1; conversely, when disassembling, only the transmission rods 301 connecting the two need to be removed without involving the other transmission rods 301, etc.

[0029] Preferably, the transmission kit 2 includes a tensioning part 206, which is used to ensure the meshing between the transport belt 203 and the transmission gear 202. Any component or kit that can tighten the transport belt 203 and thus mesh with the transmission gear 202 is applicable. More preferably, such as Figure 3 As shown, in this embodiment, the tensioning part 206 includes a set of telescopic components 206-1. One end of the telescopic component 206-1 is fixed to the base 201, and the other end is fixed to a set of transmission gears 202 placed at the end of the transport belt 203. The telescopic component 206-1 controls the spacing between the two sets of transmission gears 202 placed at both ends of the transport belt 203 by adjusting the relative distance between the transmission gears 202 and the base 201. Ultimately, it achieves the effect of forcing the two sets of transmission gears 202 away from each other, thereby tightening the transport belt 203 to achieve stable mutual meshing. The telescopic component 206-1 can be any component or kit that can achieve the spacing adjustment effect, such as a telescopic rod structure, a threaded rod, or a plate screwed onto the threaded rod. Compared to additional structures such as tensioning wheels, the tensioning part 206 involves fewer overall parts, achieving the tensioning effect while also contributing to the overall weight reduction of the transmission module.

[0030] Preferably, such as Figure 3 As shown, in the transmission kit 2 including the drive gear 205, its tensioning part 206 also includes two sets of drive tensioning rollers 206-3. The two sets of drive tensioning rollers 206-3 are respectively placed between the drive gear 205 and the transmission gear 202. The drive tensioning rollers 206-3 abut against the outer wall surface of the transport belt 203 to force the transport belt 203 to mesh with the drive gear 205. This avoids phenomena such as tooth skipping between the drive gear 205 and the transport belt 203 during operation, ensuring that the torque of the drive gear 205 is normally transmitted to the transport belt 203, and reducing the power loss of the drive motor.

[0031] Preferably, such as Figure 4 As shown, the support portion 204 includes a support plate 204-1 and guide blocks 204-2 disposed on the support plate 204-1. The support plate 204-1 has a support surface 204-3 that contacts the inner wall of the transport belt 203. The guide blocks 204-2 are disposed on both sides of the support surface 204-3, forming a support space to accommodate the transport belt 203. In this structure, the support plate 204-1 provides partial support for the transport belt 203, while the guide blocks 204-2 prevent the transport belt 203 from shifting and falling out of the support range of the support surface 204-3 during long-term use.

[0032] Preferably, a limited height L3 is formed between the top of the guide block 204-2 and the supporting surface 204-3; when the transmission kit 2 is not carrying any items, such as Figure 5 As shown, a first working height L1 is formed between the inner wall of the transport belt 203 and the supporting surface 204-3; when the transport kit 2 carries an item, as Figure 6 As shown, a second working height L2 is formed between the transport surface 203-1 formed by the outer wall of the transport ring 203 and the support surface 204-3; the limiting height L3 is located between the first working height L1 and the second working height L2.

[0033] When the transmission kit 2 is unloaded, the inner wall of its transport ring 203 is usually suspended above the support surface 204-3, which can reduce the wear of the transport ring 203 by the friction between the two. At this time, the limiting height L3 is higher than the first working height L1 to ensure that the transport ring 203 is still limited by the guide block 204-2 and will not fall off within the support space.

[0034] When the transport kit 2 is carrying an item, the item will press down on the transport belt 203 to descend. If the transport belt 203 is made of a flexible material such as rubber, it will also cause a small amount of compression in the thickness direction. At this time, by restricting the height L3 to be lower than the second working height L2, it is ensured that the transported item will only contact the transport surface 203-1 and not the top surface of the guide block 204-2. This ensures that the transported item is always driven by the transport belt 203 to move, avoiding the occurrence of contact between the item and the guide block 204-2, which would cause large friction and make it difficult for the item to move.

[0035] Preferably, such as Figure 1 As shown, five sets of transmission kits 2, excluding the drive gear 205, are respectively arranged on both sides of the transmission kit 2 containing the drive gear 205. Two sets of transmission kits 2 are arranged on one side, and three sets of transmission kits 2 are arranged on the other side. This arrangement ensures that the transmission kit 2 with the drive gear 205 is not placed at the outermost position among several sets of transmission kits 2. This structure ensures that the active transmission kit 2 can simultaneously and evenly transmit torque to the passive transmission kits 2 located on both sides, thereby ensuring a more uniform distribution of transmission power throughout the transmission module. Example 2:

[0036] The difference between this embodiment and Embodiment 1 is that, as Figure 1As shown, the transmission unit 3 includes a transmission rod 301, and the transmission gears 202 on the same side of the six sets of transmission kits 2 are all mounted on the transmission rod 301. Although this structure increases the difficulty of disassembling and removing transmission kits 2 when adding or removing them compared to the structure in Embodiment 1, it is still more convenient than the disassembly and assembly of components such as transfer belts in the prior art. Furthermore, mounting multiple sets of transmission gears 202 on the same transmission rod 301 further reduces transmission losses between multiple sets of transmission kits 2 and improves the synchronization of multiple sets of transmission kits 2, thereby ensuring that the overall transportation effect of the transmission module, such as the transportation speed, remains consistent. Example 3:

[0037] The difference between this embodiment and Embodiment 1 is that, as Figure 7 As shown, in the transmission kit 2 without the drive gear 205, the tensioning part 206 includes a set of adjustable tensioning pulleys 206-2. Figure 8 As shown, an adjustment groove 201-1 is provided on the base 201, and an adjustable tension wheel 206-2 can be installed in the adjustment groove 201-1 via rivets, screws, or other components. In this structure, the adjustable tension wheel 206-2 can move relative to the base 201-1 and be fixed in its relative position after reaching the desired position. Simultaneously, the adjustable tension wheel 206-2 is positioned between two sets of transmission gears 202 and abuts against the transport belt 203. Therefore, when the adjustable tension wheel 206-2 slides in the adjustment groove, it can move towards the inner ring surface of the transport belt 203 to provide tension, forcing the transport belt 203 to contract inward, thereby meshing with the transmission gears 202 placed on its inner wall surface, thus achieving a tensioning effect.

[0038] In the transmission kit 2 equipped with drive gear 205, the adjustable tension wheel 206-2 can replace a set of drive tension wheels 206-3 and together with the remaining set of drive tension wheels 206-3, achieve the tensioning effect on the transport belt 203. Example 4:

[0039] The difference between this embodiment and embodiment 3 is that, as Figure 9 and Figure 11As shown, the support portion 204 in this embodiment includes five sets of support rollers 204-4, with a support area 204-5 formed on the top of each set of support rollers 204-4. During the rotation of the support rollers 204-4, any arc surface on them can provide support for the transport belt 203 after rotating into the support area 204-5. This allows the support areas 204-5 on the five sets of support rollers 204-4 to jointly support the outer wall surface of the transport belt 203, forming a transport surface 203-1. With this structure, during use, the transport belt 203 can drive the support rollers 204-4 to rotate, thereby reducing friction between them and making the operation of the transport belt 203 smoother. This helps improve the overall operating efficiency of the transmission module and reduce energy consumption.

[0040] Preferably, the supporting roller 204-4 is a gear structure, and its teeth can mesh with the toothed surfaces on the inner wall of the transport ring belt 203. With this structure, when the transport ring belt 203 is driven to move, it can directly drive the supporting roller 204-4 to rotate, further reducing the phenomenon of slippage and other mutual friction between the two. This further enhances the supporting effect of the supporting part 204 on the transport ring belt 203 while reducing obstacles to its transport operation. Example 5:

[0041] This embodiment provides a transfer machine, which includes a lifting base, a transmission module from embodiment 2 mounted on the lifting base, and a first transmission unit A. Figure 10 As shown, the first transmission section A includes seven sets of first transmission components A01. In this embodiment, the first transmission component A01 is a transmission roller. A working channel A02 is formed between two adjacent sets of transmission rollers to accommodate the transmission kit 2 in the transmission module to move up and down.

[0042] The lifting base can be a common commercially available transfer machine lifting base, which controls the transport surface to be higher or lower than the transport surface of the transport roller by raising or lowering the transport module.

[0043] When the transport surface of the transport module is higher, the item moves along its transport direction under the influence of the transport module; when the transport surface of the transport module is lower than the transport surface of the transport roller, the item moves along the transport direction of the transport roller under the influence of the transport roller.

[0044] In this embodiment, a first angle α is formed between the transmission direction of the first transmission unit A and the transmission direction of the transmission module. When viewed from a top-down perspective, the first angle α is 90°. This allows the transport of items on the transmission module in different directions to achieve a transfer effect by raising and lowering the module. Example 6:

[0045] This embodiment provides a transfer machine, which differs from Embodiment 5 in that, as shown in the following... Figure 11 As shown, the transmission module used consists of six sets of transmission kits 2 as described in Example 4.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
