- the end of the bracket support rail 60a on the yarn introduction side will be referred to as “rail upper end (indicated by reference numeral 60au in the figure;)”, and the end of the yarn discharge side will be referred to as “rail lower end (indicated by reference numeral 60ad in the figure). ;)) ".
- the bracket 60 and the bracket support rail 60a are provided, and the bracket 60 according to the first to third embodiments is replaced with the moving means.
- the operator can reach the hand and directly move it by operating an appropriate rod (not shown).
- a second switching valve S1 (S2) to be described later is provided on the rail upper end 60au of the bracket support rail 60a.
- This second switching valve SI (S2) is configured as a so-called four-port switching valve, and its operation method is based on mechanical operation (specifically, a roller lever type). Then, when the bracket 60 rises along the bracket support rail 60a and reaches the rail upper end 60au, the bracket 60 engages with the second switching valve SI (S2), whereby the second switching valve S1 The state of (S2) is configured to be switched.
- the second switching valve SI (S2) is configured like a so-called mechanical switch.
- the primary heater 102 is configured to simultaneously receive a pair of yarns 2.2 in the recess 12 as shown in Figs.
- the bracket 60 and the bracket support rail 60a described above are provided so as to correspond to each thread 2. Therefore, one primary heater 102 is provided with a pair of the brackets 60 and 60 and the bracket support rails 60a ′ 60a, and the second switching valve SI ′ S2.
- Each of the weights is provided with unillustrated thread breakage detecting means for detecting thread breakage, and this thread breakage detecting means is connected to the moving means of the bracket 60. And When the yarn break detecting means detects the yarn break, the moving means is instructed, and the moving means
- the bracket 60 positioned at the rail upper end 60au is configured to move to the rail lower end 60ad.
- the operation method of the four-port switching valve 18B is based on predetermined human power means.
- the operation method of the 4-port switching valve 18B is based on a combination of pilot operation (so-called indirect pilot) and mechanical operation (using a panel).
- the pilot pressure for operating the 4-port switching valve 18B is configured to be supplied by another air compressor and motor 18CC provided separately.
- the pair of second switching valves S 1 and S2 are interposed in series.
- each of these second switching valves S1 'and S2 is a roller lever type, and is in a vented state only when engaged with the bracket 60. Engaged with bracket 60, sometimes configured to be non-ventilated! RU
- the primary heater 102 is configured as described above. Next, the operation of the primary heater 102 will be described.
- any one of the pair of second switching valves S1 ′ S2 is switched to the non-venting state, thereby cutting off the supply of pilot pressure to the four-port switching valve 18B.
- the door 14 Moves to the open position.
- the worker hung the yarn 2 from the yarn supplying section 1A to the secondary heater 105 on the bracket 60 positioned at the rail lower end 60ad as a result of the lowering, and The bracket 60 is raised by moving means.
- the bracket 60 reaches the rail upper end 60au, the thread 2 is inserted into the primary heater 102, and at the same time, the bracket 60 is switched to the non-ventilated state. (Or S2) is engaged, and the second switching valve S1 (or S2) is switched to the ventilation state again.
- the supply of pilot pressure to the 4-port switching valve 18B is resumed, and as a result, the door 14 moves to the closed position.
- the primary heater 102 automatically opens and closes the door 14 (without operator judgment) in conjunction with the yarn hooking operation (thread setting operation). It is configured to be. Therefore, as compared with the third embodiment, it is not necessary to be aware of the opening / closing operation of the door 14 during the threading operation, so that the workability of the threading operation is improved and the threading operation is finished. It is possible to prevent human errors such as forgetting to close the door 14 at a very effective time.
- the rod 18 is attached to the operator side (front side) of the primary heater 102. Need to be placed in the third embodiment and the fourth embodiment, the rod 18 is configured to be driven by the pneumatic cylinder 18A. Therefore, the rod 18 is connected to an operator and the primary heater 102. It can also be placed on the opposite side across . That is, the wires wl to w3 stretched in the vicinity of the rod 18 can be arranged on the back side of the primary heater 102.
- the urging coil panel 49 A shown in FIG. 22 may be provided instead of the urging panel 49 shown in FIG. 22
