Abstract
The utility model relates to a disconnection detecting device for a book sewing machine, and the device comprises a torsion spring, an induction rod and a fixed shaft; respective both ends of the induction rod and the fixed shaft are fixed on the left and the right brackets; the torsion spring is fixed on the fixed shaft; a through hole is arranged at the end part of an elastic extended end of the torsion spring, and the extended end of the torsion spring is separated from the induction rod with the pulling force of wire; and one end of the induction rod and one end of the fixed shaft are respectively connected with a disconnection control system. The disconnection detecting device has the principle and the beneficial effects that: the binding line of the book sewing machine can run through the through hole of the torsion spring and bend the torsion spring through pulling; the spring can be repositioned at the time of disconnection to contact with the induction rod, the induction rod, the fixed shaft and the book sewing machine can form a loop; the disconnection control system sends the alarming signals and automatically close the book sewing machine so as to make the machine stop working; and the book sewing machine can be stopped working in time at the time of disconnection occurrence so as to reduce the waste ratio of binding, send out the alarm signals at the same time, and remind workers of detecting.
Description
Technical field
The utility model relates to a kind of book sewing machine, relates in particular to a kind of broken thread detector that is used for book sewing machine.
Background technology
During the book sewing machine bound book, by the frame of stapling together the paper card is delivered to gutter pos, end pin promptly moves upward once and accomplishes fluently pin hole, and bearded needle colludes linear survive circle and knotting, finishes the bookbinding of paper card.Yet, in the nail line process, broken string, broken needle occur and do not collude problem such as line at existing book sewing machine, broken string takes place in the past can only therefore influence operating efficiency, improved paper card bookbinding percent defective, more be not easy to administer and maintain by manually checking discovery through regular meeting.
Summary of the invention
The utility model has overcome the defective of prior art, provides a kind of and can in time detect book sewing machine broken string situation and make book sewing machine quit work, in time provide the checkout gear of alarm signal.
The utility model is to realize the book sewing machine break wire device like this: the broken thread detector that is used for book sewing machine, this device comprises torsion spring, induction rod and fixed axis, induction rod and fixed axis two ends separately all are fixed on the left and right insulating support, torsion spring is fastened on fixed axis, the end of the elasticity external part of torsion spring is provided with through wires hole, and the elasticity external part of torsion spring is subjected to the pulling force constraint of line and breaks away from induction rod; An induction rod and fixed axis end separately all is connected with the broken string control system.
As preferably, the broken string control system includes continuous control circuit, Programmable Logic Controller and man-machine interface, and control circuit connects induction rod and fixed axis.
As preferably, torsion spring is fixed on the fixed axis by positioning sleeve.
As preferably, described left and right insulating support is a bakelite.
Adopted the principle of the present utility model and the beneficial effect of technique scheme to be: the cord of book sewing machine passes the through wires hole of torsion spring also the torsion spring stretch bending, make the elasticity external part of torsion spring break away from induction rod, when broken string takes place when, torsion spring resets, the elasticity external part touches induction rod, induction rod, fixed axis and broken string control system form the loop, the broken string control system is sent alarm signal and is closed book sewing machine automatically, it is quit work, book sewing machine can in time quit work when broken string takes place thereby make, reduce the bookbinding percent defective, sent alarm signal simultaneously, reminded the staff to carry out upkeep operation.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Embodiment: as shown in Figure 1, the broken thread detector that is used for book sewing machine, comprise torsion spring 3, induction rod 2 and fixed axis 5, induction rod 2 and fixed axis 5 two ends separately all are fixed on the left and right insulating support 1, and left and right insulating support 1 is a bakelite, can not conduct electricity, torsion spring 3 is fastened on fixed axis 5 by positioning sleeve 4, the end of the elasticity external part 6 of torsion spring 3 is provided with through wires hole 7, and the cord of book sewing machine passes in through wires hole 7, and with elasticity external part 6 stretch bendings of torsion spring 3; Induction rod 2 and fixed axis 5 end separately all is connected with the broken string control system, and the broken string control system includes continuous control circuit, Programmable Logic Controller and man-machine interface, and control circuit connects induction rod 2 and fixed axis 5.
When broken string takes place when, torsion spring 3 is because the effect of self elastic force resets, touch induction rod 2, induction rod, fixed axis and control circuit form the loop, control circuit sends signal and gives Programmable Logic Controller, Programmable Logic Controller sends signal quits work book sewing machine, and sends alarm signal and remind operating personnel to overhaul on man-machine interface.
