Description

TECHNICAL FIELD

[0001] The utility model belongs to light industry product assembly line production equipment technical field, specifically related to a kind of circulating transmission device with turnover basket posture keeping function. BACKGROUND

[0002] The typical examples of the above-mentioned light industry products are clothing, and the concept and positive significance of clothing production assembly line can be fully understood by reading patent documents such as CN102807061B, CN203728035U, CN112875174A, CN202276226U, KR20160026659A, DE414405761A1, JP2000-219309A, US4050575A and EP0623530A1, etc. Especially through reading CN107117439B recommended "circulating transmission device" and CN116142691A provided "single and double line interchangeable assembly line", a more thorough understanding is obtained.

[0003] According to professional knowledge, as long as the transmission device of the turnover basket is designed as a single-layer and ring-shaped running track structure, the turnover basket can move in a circle on the same horizontal plane without changing its posture, such as the basket opening alternating upward and downward. The aforementioned CN107117439B is the case. However, the aforementioned structure is large in size and easily occupies valuable space in the workshop. If the structure is designed as a double-layer as in the aforementioned CN116142691A, the length can be significantly shortened, effectively reducing the space occupation in the workshop. However, when the turnover basket reaches the end and turns, that is, when the turnover basket is in the lower layer, the posture of the turnover basket changes relative to the posture of the upper layer. Specifically, when moving in the upper layer, the basket opening of the turnover basket faces upward, and the contents in the basket will not fall to the floor. When moving to the lower layer, the basket opening of the turnover basket faces downward, and there are no contents in the basket, otherwise the contents will spill out. Moreover, in order to intelligently dispatch the contents in the turnover basket to any station of the production line, reflecting the superiority and convenience of the station that will not be rearranged due to the change of each style, the turnover basket must be able to move in a closed loop within the assembly line. If the turnover basket can only move in the upper layer and cannot form a closed loop, the turnover basket cannot circulate and be successfully and intelligently dispatched to the designated station, thus failing to achieve the purpose of intelligent dispatch.

[0004] For example: the 10th station of the production line, according to the running direction of the assembly line, the next station is 11, and the previous station is 9, that is, the running order of the turnover basket is first through 9, then through 10, and then through 11, and so on. If the scheduling needs according to the sewing process sequence, after the 10th station is completed, the next one is 9, not 11, which is behind the 10th station. The running direction of the assembly line is kept in one direction, which requires the assembly line to send the completed items of the 10th station to the tail end of the assembly line, and then the turnover basket is transferred from the upper layer to the lower layer of the assembly line. During the transfer process, the turnover basket needs to keep the opening upward to ensure that the items in the turnover basket do not fall out. When the turnover basket with the items runs in the opposite direction of the upper layer in the lower layer, it will pass through the 9th station again, so that the items can be smoothly sent to the 9th station, the most direct transportation path, and the most efficient transportation. Of course, according to the intelligent scheduling needs, if the 9th station currently has inventory and does not need to be taken out temporarily, the items need to be temporarily stored in the turnover basket of the assembly line as buffer inventory and continue to run, pass through the lower layer and send to the front end of the assembly line, and then the turnover basket is transferred from the lower layer to the upper layer. When running in the upper layer, it will pass through the 9th station again. This is a relatively long transportation path, which is determined by the algorithm of the control system. However, no matter how, objectively, the turnover basket of the assembly line must be able to run in a closed loop. When transferring between the upper and lower layers, the opening of the turnover basket remains unchanged, and the items cannot fall out. In addition, the number of turnover baskets of the foregoing CN116142691A is also subject to certain restrictions. This is because it is in the form of upper and lower layers, but objectively it is like a single layer, because as mentioned above, when the turnover basket is in the lower layer, the basket cannot store items.

[0005] Based on the above prior art, it is of great significance to explore a double-layer structure that can achieve good collection degree, save space occupation, meet the requirements of small batch and multi-variety without rearranging the stations, and enable the posture of the turnover baskets in the upper and lower layers to keep the basket opening upward for circulating transmission device. The technical solution to be introduced below is produced in this background. Practical new type content

[0006] The task of the present application is to provide a circulating transmission device with turnover basket posture maintaining function, which can significantly reduce the occupation of space, shorten the running path and improve the running efficiency, and achieve excellent collection degree. The posture of the turnover basket moving to the lower layer is always consistent with the posture of the turnover basket moving in the upper layer, which can achieve the true double-layer effect and facilitate workers to take or place items from the upper or lower layer, and can meet the requirements of small batch and multi-variety without rearranging the stations, and can achieve good adaptability to process requirements.

[0045] By Figure 5 And Figure 6As shown, the aforementioned front guide plate 85 and rear guide plate 86 are rhomboid in shape.

[0046] As mentioned above, the applicant describes how the front and rear traction chains 3 and 4 of the turnover basket move under the operation of the traction chain drive mechanism 2. Specifically, the front traction chain 3 moves repeatedly around the upper left and lower left sprockets 31 and 32 located on the left rear side of the front frame 11, and the upper right and lower right sprockets 33 and 34 located on the right rear side of the front frame 11. Simultaneously, the rear traction chain 4 moves repeatedly around the upper left and lower left sprockets 41 and 42 located on the left front side of the right frame 12, and the upper right and lower right sprockets 43 and 44 located on the right front side of the rear frame 12. Since the front and rear traction chains 3 and 4 of the turnover basket are connected to the front and rear traction chain connecting plates 83 and 84 of the structural system of the turnover basket moving guide mechanism 8, the turnover basket moving guide mechanism 8 (one turnover basket 5 is equipped with one turnover basket moving guide mechanism 8) moves accordingly as the turnover basket 5 moves repeatedly. During the movement, the aforementioned front long guide column roller 8511 forms a rolling pair with the front frame upper beam guide bar groove 11111 and the front frame lower beam guide bar groove 11211, while the aforementioned long guide column roller 8611 forms a rolling pair with the aforementioned rear frame upper beam guide bar groove 12111 and the rear frame lower beam guide bar groove 12211. When the turnover basket moving guide mechanism 8, carrying the turnover basket 5, moves from right to left to a position corresponding to the upper part of the front and rear left retaining plates 6 and 7 of the aforementioned turnover basket posture, the turnover basket moving guide mechanism 8, in a state of forming a rolling pair with the opposite side of the front and rear left retaining plates 6 and 7 of the turnover basket posture, turns left to change direction and moves downward. When it reaches the bottom of the front and rear left retaining plates 6 and 7 of the turnover basket posture, it turns right to change direction and at the same time moves with the aforementioned front frame upper beam guide groove 11111 and front frame lower beam guide groove. When the upper beam guide groove 12111 and the lower beam guide groove 12211 of the rear frame form a rolling pair, and the basket moves from left to right to the position between the lower part (bottom) of the front and rear right retaining plates 10 and 20 of the aforementioned turnover basket posture, the turnover basket moving guide mechanism 8 turns right, changes direction, and moves upward. When it reaches the position between the top of the front and rear right retaining plates 10 and 20 of the turnover basket posture, it turns left again, changes direction, and moves again towards the front and rear left retaining plates 6 and 7 of the turnover basket posture. This process is repeated to make the turnover basket 5 present a position from... Figure 1 and Figure 2 The upper and lower layers shown move in a cyclical manner. During this cyclical movement, the open portion of the turnover basket 5 always faces upwards.

[0047] To facilitate a clearer understanding of this utility model, the applicant, in conjunction with...Figure 5 The following is described: the rear short guide roller 8621 enters the short guide roller guide groove 74 in a state of forming a rolling pair with the short guide roller upper guide surface 71, and until the rear left holding plate 7 of the rotary basket posture moves out to the right in a state of forming a rolling pair with the short guide roller lower guide surface 72, at the same time, the rear long guide roller 8611 rolls along the long guide roller guide upper horizontal groove 75a and enters a pair of long guide roller guide grooves 73 through the ∧-shaped transition passage area 75c, and then moves out the rotary basket posture rear left holding plate 7 through the ∨-shaped transition passage area 75d and the long guide roller guide lower horizontal groove 75b. Since the forms of the rotary basket posture front left holding plate 6, the rotary basket posture front and rear right holding plates 10, 20 entering and moving out are the same as described above, the applicant will not repeat them.

[0048] In summary, the technical scheme provided by the utility model makes up for the shortcomings in the prior art, successfully completes the invention task, and truly realizes the technical effects described by the applicant in the technical effect column above.
