Description

Technical Field

[0001] This application relates to the technical field of rubber supply and conveying in a mixing workshop, and in particular to an automatic rubber supply and conveying mechanism. Background Technology

[0002] Glue supply and conveying mechanisms play a crucial role in industrial production, especially in mixing workshops. In related technologies, to achieve automated pallet conveying, a single conveyor belt or roller conveyor structure is typically used to complete the pallet transfer task. These traditional solutions mainly include the following methods: one is to use a single conveyor belt in conjunction with baffles to position the pallet and ensure its stability during transport; the other is to use a roller conveyor combined with photoelectric sensors to detect the pallet's position, thereby achieving basic positioning functionality.

[0003] However, the aforementioned traditional solutions generally share a common problem: when simultaneously adapting to different types of pallets (such as iron pallets and plastic flat pallets), it is difficult to meet the conveying needs of both types of pallets, resulting in low conveying efficiency. Furthermore, during the conveying process, the lack of an effective coordination mechanism can easily lead to pallet accumulation or obstructed conveying, thereby affecting the smooth operation of the overall production process. Utility Model Content

[0004] In order to accommodate both iron pallets and plastic flat pallets, this application provides an automatic glue supply conveying mechanism.

[0005] The automatic glue supply mechanism provided in this application adopts the following technical solution:

[0006] An automatic glue supply conveying mechanism includes a control component, a first pallet detection component, and a front-end conveying device, a central conveying device, and a rear-end conveying device continuously arranged along a first direction. Each of the front-end, central, and rear-end conveying devices includes a conveying structure, a synchronizing rod, and a drive motor. Two conveying structures are arranged along the first direction and are connected by a synchronizing rod. The drive motor drives the synchronizing rod to rotate, simultaneously driving both conveying structures to transport pallets. The first pallet detection component is located at the end of the central conveying device, between the two conveying structures. The first pallet detection component is upwardly positioned to detect any obstructions above it. The first pallet detection component is signal-connected to the control component, which in turn is signal-connected to the front-end, central, and rear-end conveying devices.

[0007] By adopting the above technical solution, simultaneous adaptation to both iron pallets and plastic flat pallets is achieved, ensuring pallet stability during transportation. The first pallet detection component can accurately locate the pallet at the central conveyor, ensuring that the pallet can cooperate with the film conveyor. The overall structure coordinates the operation of the front-end conveyor, central conveyor, and rear-end conveyor through control components, improving the automation level and working efficiency of the automatic glue supply conveying mechanism.

[0008] Optionally, the front-end conveying device and the rear-end conveying device have the same length, and the length of the front-end conveying device is greater than the length of the central conveying device.

[0009] By adopting the above technical solution, the front-end conveying device and the rear-end conveying device are the same length and longer than the central conveying device, which allows for a reasonable allocation of space for each conveying device. This design enables the front-end conveying device to accommodate more pallets to be dispensed, ensuring the continuity of the dispensing process; at the same time, the rear-end conveying device has sufficient length to transport empty pallets away from the central conveying device, preventing pallets from piling up at the central conveying device due to untimely retrieval, thereby improving the operating efficiency and stability of the entire automatic dispensing mechanism.

[0010] Optionally, a second pallet detection component is also included. The second pallet detection component is located at the end of the front-end conveying device and between the two conveying structures of the front-end conveying device. The second pallet detection component is configured to detect whether there is an obstruction above it. The second pallet detection component is signal-connected to the control component.

[0011] By adopting the above technical solution, the second pallet detection component is located at the end of the front-end conveyor and can detect the presence status of the pallet at the front-end conveyor. Combined with the positioning function of the first pallet detection component for the pallet at the central conveyor, the second pallet detection component can ensure that the pallet at the front-end conveyor stops moving when there is already a pallet at the central conveyor, thus avoiding interference with the coordinated operation of the pallet at the central conveyor and the film transporter.

[0012] Optionally, both the first tray detection component and the second tray detection component are photoelectric sensors.

[0013] By adopting the above technical solution, the photoelectric sensor possesses high sensitivity and fast response characteristics, enabling non-contact detection of the pallet's presence. The photoelectric sensor not only avoids the wear problems caused by mechanical contact but also adapts to the reflective properties of pallets made of different materials, achieving indiscriminate detection of both iron and plastic flat pallets by adjusting the light intensity threshold. Combined with the logic judgment function of the control component, it can accurately identify the pallet's arrival signal, effectively eliminating the risk of false detection caused by ambient light interference.

[0014] Optionally, a film strip detection component is also included, which is used to detect whether a pallet located at the central conveyor is feeding film onto the film conveyor.

[0015] By adopting the above technical solution, the adhesive strip detection component can detect whether the pallet located at the central conveyor is feeding film to the film conveyor. After the film feeding is completed, the receiver receives the signal from the transmitter, determines that the feeding is complete, and transports the empty pallet to the rear conveyor, thereby avoiding interference with the adhesive feeding operation of the pallet located at the central conveyor.

[0016] Optionally, the adhesive strip detection assembly includes a through-beam sensor, which includes a transmitter and a receiver. The transmitter and receiver are respectively disposed on both sides of the central conveying device, and the path of the ray between the transmitter and the receiver is higher than the central conveying device.

[0017] By adopting the above technical solution, the transmitter and receiver of the through-beam sensor are respectively located on both sides of the central conveyor, and the beam path is higher than the central conveyor. This allows for accurate detection of whether a pallet located at the central conveyor is feeding film onto the film transport machine. Once the film transport is complete, the receiver receives the signal from the transmitter, thus determining that the transport is complete and transporting the empty pallet to the rear conveyor, effectively avoiding interference with subsequent pallet film feeding operations.

[0018] Optionally, the conveying structure is a chain conveyor structure.

[0019] By adopting the above technical solution, the chain conveyor structure can provide stable pallet conveying performance, ensuring smooth transfer of pallets between the front-end conveyor, central conveyor, and rear-end conveyor. The chain conveyor structure has strong load-bearing capacity, adapting to the conveying needs of both iron and plastic flat pallets, while reducing pallet swaying and offset during transmission, thus improving the reliability and efficiency of the entire automatic glue supply conveying mechanism.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The two conveying structures connected by a synchronous rod drive can be adapted to both iron pallets and plastic flat pallets, improving the compatibility and flexibility of the conveying system;

[0022] 2. The first pallet detection component positions the pallet at the central conveyor to ensure the accuracy of the fit between the pallet and the film conveyor, and to avoid deviations during the conveying process;

[0023] 3. The rear conveyor can promptly transfer empty pallets to prevent them from piling up at the central conveyor, thus ensuring the smooth operation of the multi-stage conveying process. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0027] This application discloses an automatic glue delivery mechanism.

[0028] like Figure 1 As shown, the automatic glue supply conveying mechanism includes a control component, a first pallet detection component 4, and a front-end conveying device 1, a central conveying device 2, and a rear-end conveying device 3 continuously arranged along a first direction. Each of the front-end conveying device 1, the central conveying device 2, and the rear-end conveying device 3 includes a conveying structure 6, a synchronizing rod 7, and a drive motor 8. There are two conveying structures 6 arranged along the first direction. The two conveying structures 6 are connected by a synchronizing rod 7. The drive motor 8 is used to drive the synchronizing rod 7 to rotate, so as to simultaneously drive the two conveying structures 6 to transport pallets. The first pallet detection component 4 is located at the end of the central conveying device 2 and between the two conveying structures 6 of the central conveying device 2. The first pallet detection component 4 is set upward to detect whether there are any obstructions above it. The first pallet detection component 4 is signal-connected to the control component, and the control component is signal-connected to the front-end conveying device 1, the central conveying device 2, and the rear-end conveying device 3.

[0029] The automatic glue supply conveying mechanism is compatible with both iron and plastic flat pallets, ensuring pallet stability during transport. The first pallet detection component 4 accurately positions the pallets on the central conveyor 2, ensuring coordinated operation between the pallets and the film conveyor. Through the coordinated action of the control components, the overall structure enables the front-end conveyor 1, the central conveyor 2, and the rear-end conveyor 3 to operate in tandem, thereby improving the automation level and efficiency of the automatic glue supply conveying mechanism.

[0030] like Figure 1 As shown, the front-end conveying device 1 and the rear-end conveying device 3 have the same length, and the length of the front-end conveying device 1 is greater than the length of the central conveying device 2.

[0031] By rationally planning the spatial layout of each conveying device, the front-end conveying device 1 can accommodate more pallets to be supplied with glue, ensuring the continuity of the glue supply process; at the same time, the rear-end conveying device 3 has sufficient length to transport empty pallets away from the central conveying device 2, preventing pallets from piling up at the central conveying device 2 due to untimely recycling, thereby improving the operating efficiency and stability of the entire automatic glue supply conveying mechanism.

[0032] like Figure 1 As shown, in order to avoid the waiting-to-be-delivered-glue pallet from affecting the glue-being-delivered pallet, the automatic glue supply conveying mechanism also includes a second pallet detection component 5. The second pallet detection component 5 is located at the end of the front-end conveying device 1 and between the two conveying structures 6 of the front-end conveying device 1. The second pallet detection component 5 is set upward to detect whether there is an obstruction above it. The second pallet detection component 5 is connected to the control component via signal.

[0033] The second pallet detection component 5 can detect the presence status of pallets at the front-end conveyor 1. Working in conjunction with the first pallet detection component 4, which is responsible for positioning pallets at the central conveyor 2, the second pallet detection component 5 can ensure that pallets at the front-end conveyor 1 stop moving when pallets are already present at the central conveyor 2, thereby avoiding interference with the coordinated operation of pallets at the central conveyor 2 and the film transporter.

[0034] In this embodiment, both the first tray detection component 4 and the second tray detection component 5 are photoelectric sensors.

[0035] Photoelectric sensors possess high sensitivity and fast response characteristics, enabling non-contact detection of tray presence. They not only avoid the wear and tear associated with mechanical contact but also adapt to the reflective properties of trays made of different materials, allowing for indiscriminate detection of both metal and plastic flat trays by adjusting the light intensity threshold. Combined with the logic judgment function of the control components, they can accurately identify tray arrival signals, effectively eliminating the risk of false detections caused by ambient light interference.

[0036] like Figure 1 As shown, the automatic glue supply conveying mechanism also includes a glue strip detection component, which is used to detect whether the pallet located at the central conveying device 2 is feeding film to the film conveyor. Specifically, the glue strip detection component includes a through-beam sensor, which includes a transmitter 9 and a receiver 10. The transmitter 9 and receiver 10 are respectively located on both sides of the central conveying device 2, and the path of the beam between the transmitter 9 and receiver 10 is higher than the central conveying device 2.

[0037] The film strip detection component can detect whether a pallet located at the central conveyor 2 is feeding film onto the film conveyor. The transmitter 9 and receiver 10 of a through-beam sensor are respectively positioned on both sides of the central conveyor 2, with the beam path higher than the central conveyor 2. In this embodiment, the distance between the beam path and the working plane of the central conveyor 2 is the pallet height plus 30-50 mm, thereby detecting whether a pallet located at the central conveyor 2 is feeding film onto the film conveyor. After film feeding is completed, the receiver 10 receives a signal from the transmitter 9, thus determining that feeding is complete and transporting the empty pallet to the rear conveyor 3, effectively avoiding interference with subsequent pallet feeding operations.

[0038] Optionally, the conveyor structure 6 is a chain conveyor structure. The chain conveyor structure provides stable pallet conveying performance, ensuring smooth transfer of pallets between the front conveyor 1, the central conveyor 2, and the rear conveyor 3. The chain conveyor structure has strong load-bearing capacity, adapting to the conveying needs of both iron pallets and plastic flat pallets, while reducing pallet swaying and offset during transmission, thus improving the reliability and efficiency of the entire automatic glue supply conveying mechanism.

[0039] The implementation principle of an automatic glue supply conveying mechanism according to an embodiment of this application is as follows:

[0040] The trays to be dispensed with glue are placed on the front-end conveyor 1. The front-end conveyor 1 is designed to be long enough to accommodate multiple trays to be dispensed with glue, ensuring the continuity of the glue supply process.

[0041] When the first pallet detection component 4 does not detect a pallet obstructing the central conveyor 2, the front conveyor 1 continues to transport the pallet to the central conveyor 2. When the pallet is transported onto the central conveyor 2, the first pallet detection component 4 checks the pallet's presence upwards to ensure that the pallet is accurately positioned.

[0042] Meanwhile, since the film on the pallet has a certain folding height, it will trigger the adhesive strip detection component, causing it to judge that the pallet is being fed with adhesive, so it will not be transported to the rear conveyor device 3.

[0043] Subsequently, the film conveyor located on one side of the central conveyor 2 grabs the end of the film, and the pallet on the central conveyor 2 begins to feed the film onto the film conveyor. The film strip detection component detects whether the pallet is feeding film. When the film feeding is completed, the receiver 10 receives a signal from the transmitter 9, determines that the feeding is complete, and transports the empty pallet to the rear conveyor 3.

[0044] The length of the rear conveyor 3 is designed to be long enough to move empty pallets away from the central conveyor 2 and prevent pallets from piling up at the central conveyor 2 due to untimely recycling.

[0045] Furthermore, to prevent the pallet awaiting glue delivery from affecting the pallet being delivered, a second pallet detection component 5 is located at the end of the front conveyor 1 to detect the presence of pallets at the front conveyor 1. When the central conveyor 2 already has a pallet, the second pallet detection component 5 ensures that the pallet at the front conveyor 1 stops moving, thereby avoiding interference with the coordinated operation of the pallet at the central conveyor 2 and the film transport machine.

[0046] The entire automatic glue supply conveying mechanism, through the coordinated action of its control components, achieves the collaborative operation of the front-end conveying device 1, the central conveying device 2, and the rear-end conveying device 3, thereby improving the automation level and work efficiency of the automatic glue supply conveying mechanism. Simultaneously, the mechanism also achieves compatibility with both iron pallets and plastic flat pallets, ensuring the stability of the pallets during transport.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
