Abstract
A yarn sensing device for yam storage which is not fully transparent and has slits is disclosed. The optical emitter and receiver are respectively arranged on its internal surface and external side, and connected sequentially with logic operation unit, drive circuit and driver. It has high accuracy.
Description
The present invention relates to a kind of sensing device for yarn of yarn storage device, refer to especially a kind of light emission, receiving unit are located at the storage member medial and lateral of yarn storage device respectively, light source is directly transmitted, with the arrangement for detecting that prevents to judge by accident.
Press, the yarn storage device that general knitting machine is used, as shown in Figure 1, be provided with a storage member (11) in yarn storage device (1) below, use for knitting machine for the yarn that stores capacity, and known yarn storage device (1) is for predicting the yarn storage of this storage member (11), when storage is not enough, replenish in good time, usually be provided with sensing device for yarn in storage member (11), wherein, a kind of optical transmitting set and optical receiver (111) of being provided with arranged outside storage member (11), (112), utilize the principle of reflecting object, make when not having yarn in its scanning area, be about to the light reflected light receptor (112) of optical transmitting set (111), to learn the storage deficiency of yarn, thereby the essential sensitivity of strengthening sensing component, so, with making external light source cause interference, very undesirable to sensing component, and its influence that is subject to the situation change of reflecting body own is (as material, color, density, angle or pollution etc.), and produce erroneous judgement, therefore, it also has the inaccurate situation of detecting.
The sensing device for yarn that the purpose of this invention is to provide a kind of yarn storage device, the storage member of yarn storage device is made as the incomplete permeable type with space, and in this storage member, the outside is respectively equipped with one or more light emission, receiving unit, when storage member does not have yarn or yarn quantity not sufficient, after this storage member rotates to unspecified angle, has one or more optical fiber receive module at least, can receive the light source of launching from light emission component, make receiving unit that the light source that it received is converted to signal, and export arithmetic-logic unit to, via exporting the result to driving circuit after the logic operation, mend the yarn action with Control Driver, and when the yarn amount is enough, then because of optical fiber receive module can't receive light source from light emission component, and Down Drive, make and mend the yarn action and stop; Again because the medial and lateral of storage member are located in the emission of this light, receiving unit, and be the state of direct conduction light source, influence the shortcoming of accuracy to improve the reflection mode to be subject to external condition.
The object of the present invention is achieved like this: a kind of sensing device for yarn of yarn storage device, comprise the storage member that has optical transmitting set, optical receiver, light emission component, optical fiber receive module, arithmetic-logic unit, driving circuit and actuator, it is characterized in that: storage member is the incomplete permeable type with space, be respectively equipped with light emission component, optical fiber receive module in the medial and lateral of this storage member, and this light emission, receiving unit are connected in arithmetic-logic unit, and this arithmetic-logic unit is connected in driving circuit, actuator in regular turn again.
The light emission component of described storage member medial and lateral, optical fiber receive module are for being symmetrical arranged or being crisscross arranged.
Light emission component, the optical fiber receive module of described storage member medial and lateral all can be one or more assembly.
Owing to adopt such scheme: the accuracy that can improve detecting.
Principal feature of the present invention and novelty thereof cooperate the detailed description of following appended graphic embodiment, and more become bright hasty and careless, as shown in the figure:
The structural representation of the known yarn storage device of Fig. 1.
Fig. 2 structural representation of the present invention.
Fig. 3 preferred embodiment circuit diagram of the present invention.
First kind of set-up mode scheme drawing of Fig. 4 sensing component of the present invention.
Second kind of set-up mode scheme drawing of Fig. 5 sensing component of the present invention.
The third set-up mode scheme drawing of Fig. 6 sensing component of the present invention.
The 4th kind of set-up mode scheme drawing of Fig. 7 sensing component of the present invention.
See also Fig. 2,3, the present invention mainly is made as the incomplete permeable type with space with the storage member (11) of yarn storage device (1), be provided with the body of rod (12) of arrangement at storage member (11) periphery, and make between the body of rod (12) and have certain space, and in storage member (11), the outside is respectively equipped with one or more light emission component (21) and optical fiber receive module (22), wherein, after this optical fiber receive module (22) is connected to an arithmetic-logic unit (23) and one drive circuit (24), make its mouth be connected in actuator (25) (as power-transfer clutch or motor), for the signal of handling optical fiber receive module (22), and according to the state that receives, control the keying of this actuator (25), when the yarn storage deficiency of storage member (11), mend the yarn action.
Borrow aforesaid component composition, when optical fiber receive module (22) the light source of the light emission component that receives (21) when strong, then show the yarn quantity not sufficient on the storage member (11), therefore, optical fiber receive module (22) converts received light source to signal, exports arithmetic-logic unit (23) to, via exporting driving circuit (24) after the logic operation to, make actuator (25) action, mend the yarn action.
And when the yarn amount on the storage member (11) is enough, optical fiber receive module (22) can't receive the light source (or only receiving more weak light source) of light emission component (21), then arithmetic-logic unit (23) and driving circuit (24) will make actuator (25) stop, and end to mend the action of yarn relatively.
See also the set-up mode of Fig. 4-7 light emission component of the present invention (21) and light receiving element (22), can be the setting of symmetry, as Fig. 4; Or be crisscross arranged, as Fig. 5; And as shown in Figure 6, then be the emission of larger area light, receiving unit (21), (22); Certainly, as shown in Figure 7,, and receive a plurality of light emission components (21) simultaneously, also can reach the effect of detecting yarn amount equally with big optical fiber receive module (22); This light emission component, optical fiber receive module (21), (22) also can be replaced by emission, the receiving unit of (non-optical assembly) of the same type again.
In sum, the present invention is in the medial and lateral of the storage member of yarn storage device, be provided with one or more light emission, receiving unit, make it because of the set-up mode of homonymy not, and constitute the direct conduction of light source, reach the effect of detecting storage yarn amount, and avoid producing erroneous judgement because of external condition influence, be a kind of design of practicality, belong to invention, propose patent application in accordance with the law with novelty.
