Abstract
The purpose of this utility model is to provide a kind of upper thread checkout gear, and it comprises pedestal; On pedestal, be provided with guard shield; In the middle of pedestal and guard shield, be provided with encoder; Be arranged on the axle on pedestal, run through described pedestal, guard shield and encoder; Shaft end is provided with reel.Described upper thread checkout gear is installed on head, and upper thread is by reel, and band moving axis rotates, and the encoder being arranged on axle produces pulse signal, and upper thread checkout gear judgement upper thread is supplied with normal; If upper thread disconnects, axle does not rotate, and the encoder being arranged on axle does not produce pulse signal, and upper thread checkout gear judgement upper thread is supplied with abnormal.
Description
Technical field
The utility model relates to sewing machine technique field, relates in particular to a kind of upper thread checkout gear.
Background technology
Industrial sewing machine is to use one or more sewing thread, forms one or more stitchings on sewing, the machine that makes one or more layers sewing interweave or unite by a seam.The application of industrial sewing machine is very extensive, and existing industrial sewing machine surface thread detection method:
When Sewing machines is normally worked, upper thread is walked around tension disk, through thread take-up tension lever, arrives sewing needle; Thread take-up tension lever knee-action, drives the take-up hook touching copper sheet generation signal on tension disk to detect having or not of upper thread.
This detection method, if upper thread disconnects at sewing needle place, thread take-up tension lever still can knee-action, drives the take-up hook touching copper sheet on tension disk to produce signal, produces erroneous judgement disconnected; And these detection method parts are many, inconvenience is installed.
In sum, existing upper thread detection method exists improves requirement, is badly in need of a kind ofly can realizing very easily the novel upper thread checkout gear that its function does not affect again outer aesthetic.
Utility model content
The purpose of this utility model is to provide a kind of upper thread checkout gear, the defect existing for prior art, and reel drives shaft coupling to rotate, and monitors the state of supply of upper thread by built-in encoder.
To achieve these goals, the technical solution of the utility model is as follows:
In a preferred embodiment of the present utility model, it comprises pedestal; On pedestal, be provided with guard shield; In the middle of pedestal and guard shield, be provided with encoder; Be arranged on the axle on pedestal, run through described pedestal, guard shield and encoder; Shaft end is provided with reel.
Described upper thread checkout gear is installed on head, and upper thread is by reel, and band moving axis rotates, and the encoder being arranged on axle produces pulse signal, and upper thread checkout gear judgement upper thread is supplied with normal; If upper thread disconnects, axle does not rotate, and the encoder being arranged on axle does not produce pulse signal, and upper thread checkout gear judgement upper thread is supplied with abnormal.A kind of motor encoder tool of the present utility model has the following advantages:
(1) described upper thread checkout gear, installs simply, and cost is low;
(2) described upper thread checkout gear, if upper thread disconnects at sewing needle place, axle does not rotate, and the encoder being arranged on axle does not produce pulse signal, and upper thread checkout gear judgement upper thread is supplied with abnormal, can accurately detect the state of supply of upper thread.
Feature of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained and be well understood to.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail:
Fig. 1 upper thread checkout gear of the present utility model stereogram
Fig. 2 upper thread checkout gear of the present utility model profile
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the utility model.
Referring to Fig. 1, upper thread checkout gear of the present utility model, it comprises pedestal 1; On pedestal 1, be provided with guard shield 2; Pedestal 1 is middle with guard shield 2, is provided with encoder 3; Be arranged on the axle 4 on pedestal 1, run through described pedestal 1, guard shield 2 and encoder 3; Shaft end is provided with reel 5.
Described upper thread checkout gear is installed on head, and upper thread is by reel 5, and band moving axis 4 rotates, and the encoder 3 being arranged on axle 4 produces pulse signal, and upper thread checkout gear judgement upper thread is supplied with normal; If upper thread disconnects, axle 4 does not rotate, and 3 of encoders that are arranged on axle 4 do not produce pulse signal, and upper thread checkout gear judgement upper thread is supplied with abnormal.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and description, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
