Abstract
Description
Technical Field
[0001] This utility model relates to a production line for self-standing bag tube caps. Background Technology
[0002] For some stand-up pouches, since the material is granular solid or other material that is difficult to fill through the nozzle, the nozzle and sealing cap are usually assembled into a stand-up pouch cap. The stand-up pouch cap is then installed on the opening at the top of the packaging bag, while the bottom of the packaging bag is unsealed and has an opening for filling. Therefore, the semi-finished stand-up pouch with the bottom unsealed is filled through the bottom opening, and finally the bottom opening is sealed to obtain the finished package.
[0003] In the aforementioned processing method, the stand-up pouch tube cap is a key component. The traditional processing method involves using different injection molding machines to obtain sealing caps and nozzles separately. Then, a large number of sealing caps and nozzles are individually sorted and inspected using a vibratory feeder, and qualified products are collected. These are then transported to the assembly line by vehicles. Next, the nozzles and sealing caps are poured into different vibratory feeders for sorting and inspection. Then, a tube-hanging method (using vertically upright positioning rods inserted from bottom to top) is used to hang the nozzles onto the positioning rods located on the edge of an intermittent rotating turntable. A similar cap-hanging method is then used (using nozzles fitted onto vertically upright positioning rods inserted from bottom to top) to fit the sealing caps onto the nozzles fitted onto the positioning rods on the edge of the intermittent rotating turntable. Finally, a cap-tightening device is used to tighten the sealing caps, obtaining the finished stand-up pouch tube caps. After another inspection, qualified finished stand-up pouch tube caps are collected.
[0004] However, the disadvantages of this traditional processing method are: 1. Due to the defects in the existing method of attaching the sealing cap to the nozzle, both the sealing cap and the nozzle are prone to wear or damage during the process of attaching them (especially the internal and external threads that need to be matched), resulting in a high scrap rate of the self-standing bag nozzle cap; 2. The processing steps are numerous and unreasonable. The manufacturing and assembly of the sealing cap and nozzle are completed on different production lines, which occupies a lot of space, has low work efficiency, and low energy utilization; 3. Repeated use of vibratory feeder to clean the product (nozzle and sealing cap) will damage the product (nozzle and sealing cap), affect the product quality, and significantly increase the noise in the workshop. Utility Model Content
[0005] The purpose of this invention is to provide a self-standing bag tube cap production line that effectively prevents the sealing cap from colliding with the tube nozzle during the placement process. The technical solution adopted is as follows:
[0006] A self-standing bag tube cap production line, including
[0007] The rotary nozzle carrying device rotates intermittently, and multiple nozzle positioning rods for nozzle positioning are distributed sequentially along its edge. The rotary nozzle carrying device is equipped with nozzle mounting station and nozzle mounting station in sequence around its perimeter.
[0008] The nozzle conveying mechanism is located outside the rotary nozzle carrying device, and the outlet of the nozzle conveying mechanism is located at the upper nozzle station. The nozzles are sequentially fitted onto the nozzle positioning rods that pass through the outlet of the nozzle conveying mechanism on the edge of the rotary nozzle carrying device.
[0009] The sealing cap conveying mechanism is located on the outside of the rotary cap carrying device;
[0010] Its features are:
[0011] The outlet of the sealing cap conveying mechanism is located outside the upper cap station.
[0012] The stand-up pouch cap production line also includes
[0013] The sealing cap transfer and tightening mechanism places the sealing caps delivered from the outlet of the sealing cap conveying mechanism onto multiple nozzles located at the upper cover station and tightens them.
[0014] In a preferred embodiment, the nozzle conveying mechanism uses a first vibrating plate to convey the nozzle through a first conveying channel.
[0015] A preferred embodiment is that the sealing cap conveying mechanism uses a second vibratory feeder to convey the sealing cap through a second conveying channel. This reduces the number of vibratory feeders, lowers equipment cost and energy consumption, and effectively reduces noise.
[0016] In one embodiment, the sealing cap transfer and tightening mechanism employs multiple robotic arms to perform the placement and tightening of multiple sealing caps.
[0017] In another embodiment, the sealing cap transfer and screwing mechanism uses a robotic arm to complete the placement and screwing of multiple sealing caps.
[0018] In a preferred embodiment, the nozzle conveying mechanism is further equipped with a first detection device and a waste nozzle removal device. The first detection device sequentially detects the conveyed nozzles, and the waste nozzle removal device removes any defective nozzles.
[0019] In a preferred embodiment, the sealing cap conveying mechanism is further equipped with a second detection device and a waste cap removal device. The second detection device sequentially detects the conveyed sealing caps, and the waste cap removal device removes unqualified sealing caps.
[0020] In a preferred embodiment, the rotary cap carrying device is further equipped with a third detection device and a waste cap removal device. The third detection device sequentially detects the conveyed stand-up pouch caps, and the waste cap removal device removes unqualified stand-up pouch caps.
[0021] A preferred approach is to select either photoelectric detection devices or video detection devices for the first, second, and third detection devices.
[0022] In a preferred embodiment, the rotary nozzle carrying device is further provided with a torque detection station. The nozzle station, the cap station, and the torque detection station are distributed sequentially along the nozzle conveying path, and a torque detection device is installed on the torque detection station.
[0023] The advantages of this invention compared to the prior art are as follows: by using a sealing cap transfer and tightening mechanism to place the sealing caps delivered from the outlet of the sealing cap conveying mechanism onto multiple nozzles located at the upper cover station and tighten them, collisions between the sealing caps and nozzles can be effectively prevented during the placement process; the added detection device can promptly detect and remove defective nozzles, defective caps, and defective nozzle caps; and the addition of injection molding machines for manufacturing nozzles and sealing caps allows for direct conveying of the manufactured nozzles and sealing caps through the conveying channel, which greatly optimizes the production line structure, significantly improves work efficiency, greatly reduces energy consumption, and effectively reduces noise.
