Description

Technical Field

[0001] This invention belongs to the technical field of production line equipment for light industrial products, and specifically relates to a single-line circular conveyor device for turnover baskets. Background Technology

[0002] The single-line circular conveyor system for turnover baskets mentioned below is the single-line circulating conveyor system for turnover baskets. The light industrial products mentioned below include clothing, shoes, bags, electronic and electrical products, and dolls and toys, etc.

[0003] Taking clothing manufacturers as an example, the production process of a garment, such as a top, usually includes several steps such as cutting, sewing, making buttonholes, sewing on buttons, attaching pocket pieces, attaching collars, attaching sleeves, attaching plackets, sewing on labels, and ironing. These steps are often carried out in a division of labor and automation manner, which is to say, in the way people are used to. The advantages of assembly line operations are: they link employees who were previously working separately, enabling them to collaborate, identify problems promptly, reduce batch quality issues, and allow shift leaders to maintain management and tracking of each workstation, handling production line anomalies in a timely manner; they allow for effective production line management without the need for specialized managers, boosting employee morale and maximizing the potential of each employee at each workstation; they visualize bottleneck processes and hidden resources, ensuring all team members focus on bottleneck processes, fostering a collaborative team atmosphere, and relying on teamwork for mutual supervision and assistance, making it easier for managers to manage the production line, ultimately improving efficiency in a relaxed and enjoyable work environment; and they transmit output, quality, and individual completion time data to computers in real time, and as needed to cloud servers, allowing software analysis to understand each employee's actual completion time, enabling managers to understand the actual production status on computers or mobile devices, helping them manage employees and adjust their division of labor, achieving effective employee management and improved efficiency.

[0004] Early single-line circular conveyor systems for turnover baskets were generally in a closed-loop configuration. See CN201721962U (a circular conveyor system), CN102807061B (a circular conveyor system), CN202585159U (a control switch and a circular conveyor system using the control switch), CN202807786U (a circular conveyor system with a control switch), CN202807791U (a circular conveyor system with a sensor switch), CN203728035U (a production line device), CN104139962B (a belt-type circular sensing device), and CN2040... 96561U (a belt-type circulating conveyor with a brush), CN202296226U (single-piece intermittent flow trough), CN108584295A (energy-saving and noise-reducing circulating conveyor), CN107117439B (circulating conveyor), CN112875174A (single-line conveyor for turnover baskets), CN110937349A (duplex turnover box conveyor), DE4140576A1, EP0623530A1, US4050575A, US4697693A, US4548315A, FR2237822A and JP2000-219309A, etc.

[0005] While the aforementioned patents, not limited to those listed, each possess corresponding technical advantages, they share the following common drawbacks: First, once the equipment is assembled and delivered to the user (e.g., a garment manufacturer), it is typically impossible to modify it based on the specific product, the number of process steps, or the objective environmental factors of the production site, thus lacking specificity and flexibility in application. Second, they lack the function of allowing workers to choose their workstations according to their needs. For example, they are generally distributed around the outside of the assembly line in a disguised, forced manner. However, in some situations, especially when production space is limited, distributing workers in the central and / or inner / outer areas of the assembly line can significantly save space. Third, due to the lack of modularity, the number of workstations for the products to be processed is somewhat arbitrary and, to some extent, detrimental to energy conservation and flexible adjustment. This is because if the products to be processed have fewer processes, the number of processes can be reduced. The first problem is that merging processes reduces the number of operators. If the product to be processed has many steps, the steps can be broken down to increase the number of operators, requiring a high degree of flexibility. The second problem is that it easily increases the employee's turnaround time. This is because the walking route of each employee in multiple steps cannot be circular. This is because the distance between each pair of face-to-face steps is large and the intermediate partitions are unrelated, increasing the difficulty of merging and combining. Therefore, when the production cycle time of an individual step is slower than the overall production line cycle time, it is difficult for workers at other stations to provide timely support. Conversely, when an individual step is faster than the overall production line cycle time, it is difficult to assist others, affecting overall efficiency and reducing individual income. The third problem is that it is not conducive to flexibly adjusting personnel and output to adapt to flexible production. It is difficult to flexibly increase the number of personnel per unit according to changes in demand. If more are needed, more operators are added, and vice versa. This is difficult to handle in situations such as frequent changes in clothing styles, small order quantities, or even special customization of a single item. Based on the above, improvements are necessary, and the technical solution introduced below was developed in this context. Summary of the Invention

[0032] In order to better understand the technical essence and beneficial effects of the present invention, the applicant provides a detailed description below by way of embodiments. However, the description of the embodiments is not intended to limit the present invention. Any formal but not substantive equivalent transformations made based on the concept of the present invention should be considered within the scope of the present invention.

[0033] In the following description, except for the Figure 1 , Figures 10 to 13 Except where directionality and orientation are explained separately, all other descriptions involving the concepts of up, down, left, right, front, and back are based on... Figure 2 The position and state are based on the location and state, and therefore should not be construed as a special limitation on the technical solution provided by the present invention.

[0034] Please see Figure 1The diagram illustrates a power frame 1, part of the structural system of a single-line circular conveyor for turnover baskets. This power frame 1 can be directly installed on the floor of the usage site or mounted on a support structure on the floor. This embodiment chooses the latter, meaning the power frame 1 is indirectly installed on the floor of the usage site. Specifically, the aforementioned support structure is first installed on the floor of the usage site, and then the power frame 1 is mounted on the support structure. A chain drive mechanism 2 is shown, mounted on the power frame 1. A set of guide rail support frames 3 is also shown, forming a structure consisting of… Figure 1 The ring-shaped distribution shown can be directly supported on the floor of the usage site or set on a support frame supported on the floor (as described in the aforementioned power frame 1); a modular ring guide rail 4 is shown, which is supported on the power frame 1 and the aforementioned set of guide rail support frames 3; a chain carrier 5 is shown, which is movably laid on one side of the modular ring guide rail 4 and is in transmission cooperation with the aforementioned chain carrier drive mechanism 2; a set of turnover basket guide mechanisms 6 and a set of turnover baskets 7 in equal number to the turnover basket guide mechanisms 6 are shown, the set of turnover basket guide mechanisms 6 is connected to the aforementioned chain carrier 5 at intervals and the set of turnover basket guide mechanisms 6 simultaneously forms a rolling pair with the two outer sides of the aforementioned modular ring guide rail 4, and the set of turnover baskets 7 is fixed on the set of turnover basket guide mechanisms 6 respectively.

[0035] As the preferred solution and by Figure 1 As shown, guide rail support frame connecting beams 31 can also be used to connect the left and right sides of each pair of adjacent guide rail support frames 3 in the aforementioned set of guide rail support frames 3. In this embodiment, the aforementioned power frame 1 is arranged on the left side of the set of guide rail support frames 3 (i.e., on the left side). Figure 1 (Taking the position shown as an example) and located between two adjacent guide rail support frames 3 in the middle region, and preferably connected by the aforementioned guide rail support frame connecting beam 31. Of course, if the power frame 1 is located on the right side of a set of guide rail support frames 3 (taking the position shown as an example), it can also be connected by the aforementioned guide rail support frame connecting beam 31. Figure 1 Taking the position shown as an example, if the two adjacent guide rail support frames 3 are located in the middle region and are also connected by the guide rail support frame connecting beam 31, then it should be considered as an equivalent technical means.

[0036] for Figure 1Based on common sense, the structure shown can be understood as follows: the front is the entrance / exit 8 of the single-line circular conveyor for the turnover basket. Through this entrance / exit 8, workers can enter and exit the central circular area 9 in a standing position. This circular area 9 is the work area where workers perform their tasks (to be mentioned later). To facilitate workers' access to and from the aforementioned circular area, in this embodiment, the assembled circular guide rail 4 located at the entrance / exit 8 is designed in an arch shape, similar to an "n" shape or a camel hump shape. The advantages of this structural design are: since the workers work within the circular area 9, they can easily support the backlog of workstations on the left or right, as well as adjacent workstations. In particular, the support process does not require workers to make large detours and circles as in existing rhythmic production lines, thus significantly saving travel time. It can meet the requirements of small order volume changes and flexibly cope with customized orders, etc. It gets rid of the physical quantity and logical positional limitations between workstations in traditional rhythmic garment production lines, because in traditional rhythmic garment production lines, if a worker at one workstation fails to complete the work within the set time, the entire production line will stop.

[0037] Please see Figure 2 As mentioned above, the aforementioned power frame 1 is located between two adjacent guide rail supports on the left side of the aforementioned set of guide rail support frames 3. The power frame 1 has a hollow frame structure and a left guide rail support column 11 is formed longitudinally on the upper left side. On the upper right side, corresponding to the position of the left guide rail support column 11, a right guide rail support column 12 is also formed longitudinally. The tops of the left guide rail support column 11 and the right guide rail support column 12 are fixed to the aforementioned assembled annular guide rail 4. The support frame 3 also has annular guide rail support columns that are equivalent to the left and right support columns 11 and 12 of the guide rail. A support beam 13 for the chain drive mechanism is fixed at the bottom of the power frame 1. The aforementioned chain drive mechanism 2 is set on the support beam 13. The aforementioned chain 5 is in transmission cooperation with the aforementioned chain drive mechanism 2 at the position corresponding to the left support column 11 and the right support column 12 of the guide rail. The aforementioned turnover basket 7 is fixed to the aforementioned turnover basket guide mechanism 6 through the bottom wall 711 of its turnover basket cavity 71.

[0038] As a preferred option, power frame leveling feet 14 can be provided at each of the four corners of the bottom of the power frame 1.

[0039] Please pay close attention.

The chain drive motor 21 is driven by the chain drive reduction gearbox 22, and the chain drive reduction gearbox 22, together with the chain drive motor 21, is fixed to the aforementioned chain drive mechanism support beam 13 through the chain drive reduction gearbox seat 221. The chain drive reduction gearbox power output shaft 222 of the chain drive reduction gearbox 22 faces forward, and the chain drive drive drive wheel 23 is fixed to the chain drive mechanism support beam 13. On the power output shaft 222 of the chain drive reduction gearbox, one end of the chain drive transmission belt 24 is sleeved on the chain drive driving pulley 23, and the other end is sleeved on the chain drive driven pulley 25. The chain block mating wheel 26 is located between a pair of guide rail connecting frames 41. The central position of the chain block mating wheel 26 is fixed in the middle of the chain block mating wheel shaft 261. The front end and rear end of the chain block mating wheel shaft 261 are rotatably supported on the chain block mating wheel shaft support bearing seat 2612 through the chain block mating wheel shaft support bearing 2611. The chain block mating wheel shaft support bearing seat 2612 is fixed to the aforementioned guide rail connecting frame 41. The chain drive driven pulley 25 is fixed to the front end of the chain block mating wheel shaft 261. The aforementioned chain 5 is in transmission engagement with the aforementioned chain block mating wheel 26.

[0040] Depend on Figure 2 and Figure 3 As shown, the aforementioned chain block mating wheel 26 is actually a double-row wheel structure, similar to a double-row gear structure, in order to smoothly drive the chain block. Figure 7 The diagram shows the first and second chain blocks mating with wheel axle heads I5134 and II5135.

[0041] Please see Figures 4 to 6 And combined Figures 2 to 3 An earring-shaped plate 411 extends downward from the middle of the aforementioned guide rail connector 41 along its length. Figure 6 (Illustrated), a chain block mating wheel axle support bearing seat insertion hole 4111 is provided at the center of the upper part of the earring-shaped plate 411. The aforementioned chain block mating wheel axle support bearing seat 2612, together with the chain block mating wheel axle support bearing 2611, is inserted into the chain block mating wheel axle support bearing seat insertion hole 4111 and the chain block mating wheel axle support bearing seat 26121 is used to fix the chain block mating wheel axle support bearing seat 2612 to the earring-shaped plate 411.

[0042] exist Figure 4The diagram also shows a method for connecting the aforementioned guide rail connector 41 to the assembled annular guide rail 4. Specifically, one end of the guide rail connector 412 is inserted into the guide rail unit connecting strip groove 43 pre-set on the assembled annular guide rail 4 and fixed with the guide rail connector 4121 fixing screw. The other end of the guide rail connector 412, i.e. the end facing the guide rail connector 41, is also fixed with screws at the position corresponding to the guide rail connector 411, where the guide rail connector 412 has a pre-set guide rail connector 413 with a mating cavity screw hole 4131 at the bottom.

[0043] The aforementioned modular ring guide rail 4 is composed of a plurality of guide rail units connected to each other, with the ends of any two adjacent guide rail units connected by guide rail unit connecting strips 42. Figure 5 (As shown) The guide rail unit connecting slot 43 on the assembled circular guide rail 4 is fixedly connected by guide rail unit connecting slot fixing screws 421. This structural design helps garment manufacturers to reasonably increase or decrease the number of equipment units according to the batch size and duration of the garments to be processed, the number of actual process steps, and the specific space constraints. For example, the number of guide rail units constituting the assembled circular guide rail 4 can be increased or decreased to meet the requirements of targeted and flexible use. In addition, it can also avoid resource waste and reflect energy saving, etc.

[0044] Please pay close attention. Figure 7 The aforementioned chain 5 is composed of a plurality of chain block units 51 cyclically spliced ​​together. A set of chain block unit tenons 511 is formed at intervals on both the left and right sides of each chain block unit 51. The space between two adjacent chain block unit tenons 511 forms a chain block unit mortise 512. The chain block unit tenons 511 and chain block unit mortise 512 on adjacent chain block units 51 are mortised and tenoned together. The two ends of the chain block unit 51 are movably supported on the upper surface of the aforementioned assembled annular guide rail 4, forming a sliding pair with the surface of the assembled annular guide rail 4. In the use state, each chain block unit 51 has a chain block unit connecting seat 513 on its downward-facing side. The chain block unit connecting seats 513 on two adjacent chain block units 51 are connected to each other, and each chain block unit connecting seat 513 is in a transmission engagement with the aforementioned chain block mating wheel 26.
