Description

Workpiece circulating transmission device with selectable stations

Technical Field

The utility model belongs to the technical field of light industry product assembly line production facility, concretely relates to article circulation transmission device that station can be selected.

Background

The above-mentioned article circulation transmission device is mainly used in the apparel processing industry, but can also be used in the processing industry such as shoes and hats, cases, electronic and electric products, and doll toys.

Taking a clothing manufacturer as an example, the manufacturing process of a piece of clothing generally includes a plurality of procedures such as cutting, sewing, opening button holes, sewing buttons (abbreviated as "buttons"), installing zippers, bagging sheets, installing collars, installing sleeves, installing lappets, ironing and the like, and the procedures are usually performed in a division and automation manner, more specifically, by means of the article circulating transmission device, the production line operation manner has the advantages that: the system can link the employees who originally work dispersedly, cooperate with each other, find out the problems of each other in time, reduce the quality batch problems, simultaneously enable the team leader who follows the team to keep managing and tracking each station, and deal with the abnormal problems of the production line in time; the production line can be effectively managed without professional managers, the morality of staff can be improved, the potential of the staff on each station can be furthest exerted, the bottleneck process and hidden resources are visualized, all staff in a team pay attention to the bottleneck process together, team cooperation atmosphere is created, the staff supervise and assist each other by means of team strength, managers can conveniently manage the production line, and finally the efficiency is improved in the light and pleasant work pleasure; the system can timely transmit the output, the quality and the time data of personal actual completion to a computer, and transmit the data to a cloud server in real time according to needs, and the time data of each employee actually completed can be known through software analysis, so that a manager can know the actual production condition on mobile equipment such as a computer or a mobile phone, and the like, and can help the manager manage the employees and adjust the division of the employees, thereby achieving the purposes of effectively managing the employees and improving the efficiency.

The technical information about the clothing processing and related to the above-mentioned object circulation transmission device is found in the published chinese patent document, typically "a single-line and double-line interchange intelligent beat assembly line system" recommended by CN107814133B, which provides a technical solution capable of objectively honoring the technical effects described in paragraph 0013 of the specification, but because the conversion between the single line and the double line is ensured by the a-line roller electromagnetic clutch, the B-line roller electromagnetic clutch and the a-line driving electromagnetic clutch, the electromagnetic clutch has problems such as large idle torque, seized or malfunction of armature disc, easy wear and tear of friction plate, need to be replaced in time, relatively low coil reliability, cumbersome gap adjustment, easy slip and heat generation, and even short circuit of coil, on one hand, the complexity of the device is increased and the manufacturing cost of the assembly line is increased, On the other hand, the inspection and maintenance workload in the daily use process is increased; further, CN107814133B has the following disadvantages: when the single-line operation or single-line operation is carried out, the assembly line adopts a motor to drive the two conveyor belts (the material conveyor belt with the A line and the material conveyor belt with the B line) to enable the two conveyor belts to move in the same direction, but in the actual production process, the operation modes of the two conveyor belts are possibly opposite according to the process requirements to embody a U-shaped operation mode, and the U-shaped operation mode can be referred to CN201721962U (a circulating transmission device), CN102807061B (a circulating transmission device), CN202585159U (a control switch and a circulating transmission device adopting the control switch), CN202807786U (a circulating transmission device provided with a control switch), CN202807791U (a circulating transmission device provided with an induction switch), CN203728035U (an assembly line), CN104139962B (a belt circulating transmission device), CN204096561U (a belt circulating transmission device provided with a brush), CN202296226U (one-piece beat type water channel), CN108584295A (energy saving and noise reduction circulation transmission device), DE4140576a1, EP0623530a1, US4050575A, US4697693A, US4548315A, FR2237822A and JP2000-219309a, etc.

The "single-and double-wire interchange assembly line" recommended by CN111573159A abandons the electromagnetic clutch, thus making up for the above-mentioned deficiency of CN107814133B to a certain extent, and objectively honoring the technical effects summarized in the technical effects of the specification. However, CN111573159A still has the following disadvantages: firstly, the space between adjacent stations is formed by directly separating a conveyor belt station separation plate on a conveyor belt which is relatively wide, namely a conveyor belt with a certain width and without an end point, so that the electric energy consumption of the conveyor belt driving mechanism driving the drive belt to move from a driven wheel shaft and the conveyor belt sleeved between the drive belt and the driven wheel shaft driven by the drive belt from the driven wheel shaft and the movement of the conveyor belt station separation plate is relatively large, namely the electric energy consumption of a conveyor belt driving motor of a structural system of the conveyor belt driving mechanism is large due to large power, which is not beneficial to reasonably saving the cost for manufacturers using the equipment to produce products; secondly, the space between the adjacent stations is formed by separating the conveyor belt station separation plates which are distributed on the conveyor belt at intervals, the space between the adjacent stations substantially replaces a turnover basket, particularly, the inner side of the enclosure plate, the space between the two adjacent stations and the surface of the conveyor belt cooperate to form a function which is equivalent to a turnover basket, but because the surface of the conveyor belt is used as a support, in the working process, because objects are placed on the conveyor belt which is far lower than the upper plane of the enclosure plate, the taking and the placing of an operator are inconvenient, and the operator feels fatigue easily, for example, the hand of the operator needs to frequently turn over the enclosure plate to stretch into the space to take and place the workpiece; thirdly, as mentioned above, since the space formed by the cooperation of the inner wall of the containment plate, the two adjacent belt station separation plates and the belt surface replaces the revolving basket in the prior art, when the belt and the belt station separation plate disposed on the belt as a carrier move to a corner (i.e., "a turning point") such as a belt driving wheel shaft and change from a state facing upwards to a state facing downwards after passing through the corner, if the workpiece located between the belt station separation plates is not timely removed, the workpiece will inevitably fall to the bottom of the hollow frame, which is troublesome to pick up, easy to be dirty and the workpiece on the other hand, and if the workpiece is not timely removed, the belt and the belt station separation plate are interfered to normally operate; fourthly, because the conveyor belt station separation plates are adopted, the hollow spaces which are used for the conveyor belt station separation plates to pass when changing directions and can directly observe the unmasked whole conveyor belt driving mechanism and the floor from top to bottom need to be reserved at the two ends of the enclosure frame, so that on one hand, certain influence is generated on the viewing effect, and on the other hand, certain fear feeling can be generated for online operators, particularly the operators at the stations at the two ends; fifthly, because the whole structure is relatively complex, the manufacturing and installation are relatively troublesome, the economy is lost, and the inspection and protection workload is increased in daily use, for example, two curtain-type conveyor belts, two conveyor belt driving mechanisms (called as front and rear conveyor belt driving mechanisms) for driving the two curtain-type conveyor belts to move, four conveyor belt tensioning adjusting devices for adjusting the tensioning degree of the conveyor belts, a single-line operation lifting partition plate and a lifting mechanism thereof for meeting the conversion requirement of single line and double lines, and the like are adopted, so that the requirement that the relatively complex parts are in a good operation state is relatively severe; sixth, as known in the art, a beat assembly line in the prior art must be arranged in order according to a sewing process of garments, work stations (simply referred to as "stations") of an upper process and a lower process must be connected side by side, and are strictly arranged all the way until all work is completed, and the flow back cannot occur in the middle, and even cannot be arranged beyond one another at any time, so that garment production of different processes must have different arrangement modes (i.e., different station arrangement modes), which are usually suitable for garment processing of styles with relatively large order batches, but with the development trend of various and small-batch or small-batch garments, the arrangement mode suitable for large batches is difficult to adapt even not at all to a production mode with extremely limited batches or even one arrangement, and the practice of rearranging machines and workers numerous times per day is obviously unrealistic. Therefore, the production procedures are arranged to different proper working positions, the path is established according to the sewing process, and the finished article is automatically sent to the next working station at any position from one working station, namely one working station, until the whole garment is finished according to the set path, so that the worker and the machine do not need to be rearranged, the market demands of flexibly coping with a plurality of types and a small amount are met, and the flexible quick-reverse production is realized. However, the technical problem of how to automatically release the articles in the turnover basket of one station to the next station of any one station in the above process, including CN111573159A, is not reasonably suggested by all patent and non-patent documents in the prior art.

In view of the above, there is a need for improvement, and the technical solutions described below are made in this context.
