Abstract

The invention discloses a simple efficient stable sewing machine cycle operation bench, comprising a sewing bench, and a moving bench and a plate retreating bench linked to the feed side and dischargeside of the sewing bench respectively; a second plane parallel to a first plane is defined below the first plane; the moving bench may move between the first plane and the second plane in vertical lifting manner; a plate feeding bench and a transfer bench are arranged side by side on the second plane; the transfer bench is linked between the plate feeding bench and the moving bench; the plate retreating bench and the plate feeding bench are arranged in vertically spaced manner and are on the same side of the sewing bench; a feeding conveying mechanism, a discharging conveying mechanism and apending material conveying mechanism are also provided. The plate retreating bench and the plate feeding bench are arranged on the same side of the sewing bench, a jig is cyclically conveyed to the plate retreating bench from the plate feeding bench, picking and placing are performed by a single operator on the single machine, manual picking and placing are convenient to perform, manpower is saved, equipment is simpler, operational stability is better; in addition, a pending station is added to the equipment, so that operating efficiency of the equipment is improved.

Description

technical field [0001] The invention relates to the technology in the field of sewing machines, in particular to a simple, efficient and stable sewing machine circulation workbench. Background technique [0002] When the early industrial sewing machines were working, the operator needed to take the fabric to be sewn to the workbench of the sewing machine, and then the head of the sewing machine would automatically sew the fabric according to the set program. Using manual feeding and retrieving not only increases labor costs, but also causes low production efficiency, and once workers make misoperations, the machine head is easy to hurt their hands, posing a great safety hazard. [0003] In order to improve work efficiency and sewing quality, people have invented various sewing machines that can automatically take and feed materials, which can not only meet the requirements of automatic feeding and discharging, but also return the finished products on the discharging side to ...

Problems solved by technology

Using manual feeding and retrieving not only increases labor costs, but also results in low production efficiency, and once workers make misoperations, the machine head is easy to hurt their hands, posing a greater safety hazard

[0003] In order to improve work efficiency and sewing quality, people have invented various sewing machines that can automatically take and feed materials, which can not only meet the requirements of automatic feeding and discharging, but also return the finished products on the discharging side to the feeding side; Many defects, for example: in the patent document of publication number 206783944U, it records a sewing machine template conveying device, which drives the unsewn template 60 to move before the sewing P2 through the first conveying mechanism 30, or After the unsewn template 60 completes the sewing operation at the sewing position P2, the second driving assembly 41 of the second transport mechanism 40 will drive the second rotating assembly 42 to swing, so that the template 60 Move from the sewing position P2 to the board-removing standby position P3; the first moving mechanism 30 is mainly composed of a first driving assembly 31, a first rotating arm assembly 32 and a first translation arm assembly 33, Its first driving assembly 31 includes a driving source 312 and a telescopic rod 313 (that is, driven by an air cylinder), and its second transfer mechanism 40 has the same structure as the first transfer mechanism 30

[0004] In the sewing machine template conveying device of the aforementioned conventional technology, the first conveying mechanism 30 and the second conveying mechanism 40 respectively adopt a set of independent drives to realize the conveying action, that is, the two sets of drives act on the first conveying mechanism 30 and the second conveying mechanism respectively. The moving mechanism 40, on the one hand, has a complicated structure, which leads to high equipment cost; on the other hand, the fetching and feeding is a rotary translation, and the fetching and feeding actions are carried out successively. When the sewing machine is processing, there will inevitably be a waiting time, resulting in a long sewing cycle. , the work efficiency is low; moreover, the rotary arm realizes the rotary feeding and feeding, which leads to the need to provide a large enough area for the rotary action on the feeding and discharging side and the sewing table, which also leads to a large equipment volume, which is not conducive to the equipment in the workshop Place application and management

[0005] In addition, in the sewing machine template conveying device of the aforementioned conventional technology, the first conveying mechanism 30 and the second conveying mechanism 40 are respectively driven by cylinders, and each group of cylinders will be affected by the air source (for example: strength, speed, stability, etc.) ) leads to unstable displacement control, and the two sets of cylinders will affect the control accuracy of the feeding and discharging actions, and in turn, affect the operation stability of the entire device

[0006] In addition, in the sewing machine template handling device of the aforementioned traditional technology, the rotating arm is used as the manipulator for picking up and feeding materials, and the entire manipulator and the corresponding driving cylinder need to be exposed on the machine table, which has potential safety hazards.

[0007] And, in the sewing machine template handling device of the aforementioned traditional technology, it adopts a closed cycle operation mode, and in fact there is only one waiting position, that is, on the entire sewing processing cycle line, and its processing efficiency also depends on manual upper and lower jigs. Therefore, it is not conducive to ensuring the processing efficiency of automatic sewing machines, especially for workpieces with a short sewing cycle, which affects the sewing processing efficiency
