Description

DETAILED DESCRIPTION OF THE INVENTION                             Equipment used for looms   The present invention followed the desired weave pattern by weighted lifting rods. The present invention relates to a device used in a loom for raising a warp yarn.   Industrial looms are evolving rapidly from punch card control to today's machines. In keeping with the general situation in the field of computer and computer technology, this machine Has evolved into a child computer controlled machine. Of today's computer design systems The technical field controls the data medium for electronic jacquard and To control a large number of electronic jacquards via a remote computer. Of course, it is also possible to develop and process Jacquard designs as needed. I have.   It is an object of the present invention to provide a simple and inexpensive method for compiling a hand loom or hand loom. Data technology. The term "manual loom" is used at home Is used to mean the type of loom that is of interest to amateurs and professionals Used by humans, i.e. this loom is intended for the production of roughly individual goods. You. This type of loom has a relatively simple structure and follows the desired weaving pattern The presetting of the loom for raising (opening) the warp yarns is nowadays possible with a suitable perforated card system. System, but is relatively slow, and is based on computer technology. In the weaving design, the weaver can pull out on the PC screen as needed All possible designs can be actually produced.   According to the invention, an apparatus is proposed as claimed in claim 1.   The easiest way to implement the invention is with the solenoids above each Using a cylinder / piston module with a top valve controlled by . Modules are most easily embodied as cylinder blocks of the appropriate material, The cylinder block is drilled with the desired number of parallel cylinders, with A piston to which a footing rod is attached is arranged. This cylinder block A common chamber is provided above the valve, and this chamber has a solenoid above each valve. No Id is located. This common chamber is under negative or positive pressure. Atmospheric pressure Acts on the lower surface of each piston and drives them upward. piston Carries the warp with him when ascending. Which valve is opened is determined by the appropriate Pull out on PC screen via printed circuit board control device that activates the solenoid Determined by the design. As soon as the weft is completed, the piston starts Can be lowered. Thus, the cycle continues.   Several modules can be spread over a large area side by side or longitudinally on the loom Can be laid, weaving everything from narrow bands to wide woven fabrics over the full width of the loom Is possible.   The new device is simple and inexpensive and can be easily adopted in ordinary simple looms.   Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.   FIG. 1 is a schematic view of a computerized loom.   FIG. 2 is a simplified external view of a loom in which the present invention is used.   FIG. 3 is a simplified cross-sectional view of the module.   FIGS. 4 and 5 show the expanded solenoid valve in the open and closed positions, respectively, of a preferred solenoid valve. It is a large sectional view.   FIG. 1 shows the principle of a computerized loom in which the present invention is used. . Design control, weaving control and lifting system are all found in the figure .   Design control is actually a PC, while weaving control is print card control It includes the equipment and the necessary pumps to supply negative pressure and suppression. Lifte The working system includes a cylinder block. Actually, the cylinder block and The valve block is configured as one piece as shown in FIG.   FIG. 1 shows a cylinder block 1. How to add dashed lines Similar blocks 2, 3 and 4 of the above in the warp direction determined by the warp yarn 5 Indicates whether to juxtapose with the block. Separate blocks or modules may also be They can be arranged side by side, ie transversely to the warp direction.   In each block 1, there are a plurality of cylinders provided with pistons. The tons are attached to each lifting rod 6. Each lifting rod The pad has a warp eyelet 7 in a known manner, and is weighted by an appropriate weight 8. I have.   FIG. 2 is a simplified side view of the loom 9. The warp yarn is designated by the reference numeral 5. Each warp yarn is lifted so that the yarn passes through the lifting rod eyelet 7. It is attached to the swinging rod 6. Lifting rod 6 supports weight 8 . The lifting rod 6 moves up in the cylinder block 1. This cylinder blow The hook 1 is suspended in the loom by a suitable support stay 10. Cylinder blow At the top of the rack 1 is a housing 11. This housing is inside the cylinder block Form a common chamber for the cylinders.   FIG. 3 is a simplified sectional view of the block 1 provided with a common chamber. block And the common chamber form a module that can accommodate the desired number of cylinders. On the drawing Module is shown as having a row of cylinders arranged in a horizontal direction. However, the module contains several rows of parallel cylinders, for example 20 cylinders in three rows. Can be tolerated.   In the simplified sectional view of FIG. 3, the cylinder block 1 It can be seen that it has. Lifting rod protruding downward in cylinder 12 A piston 13 with 6 is arranged.   The common chamber 11 is provided at the top of the cylinder block 1. In this room, A plurality of solenoid operated valves 14 are arranged, one for each cylinder 12. Electric The current is supplied to the solenoid winding 15 via electric wires 16 and 17. Common room 11 Is connected to a pump device via a connection pipe 18.   The solenoid operated valve is shown enlarged in FIGS. The valve 14 has a winding 15 And a housing body including a solenoid core 19 provided with Have been. The housing body is inserted into the upper open end of the cylinder as shown in FIG. On the intermediate part 20 designed to be inserted. The intermediate portion 20 includes a cylinder 12 There is a hole 21 for the flow of air to the air. The middle section 20 has a blind hole 22 (FIG. 5). An armature or valve stem 22 passes through this hole. The valve stem 22 is an O-ring 23 has an annular groove arranged therein. The O-ring is located inside the housing body There is a valve seat 24 above the O-ring inside the housing body. A hole 25 for air circulation is provided immediately above the valve seat 24.   In FIG. 4, the valve is open with no current and the O-ring 23 is Away from In FIG. 5, the armature or valve stem uses an electric pulse O-ring 23 is sealed against valve seat 24 as a result of receiving It is dormant. The valve is closed.   Yarn control functions in the following manner.   As described above, valves 14 are located at the top of each cylinder 12. The valves are in a common chamber connected to the pump device shown in FIG. Individual syringe A piston 12 connected by a lifting rod 6 to the yarn in the loom There are thirteen. When the valve is opened and the common chamber is placed under negative pressure, Then, the piston 13 is sucked upward. Large underside of piston Driven by atmospheric pressure.   Within a module, a number of valves and cylinders are mounted or mounted side by side in a block. Is formed. All valves can operate independently of each other.   If the other piston is raised while the piston 13 is down, The following happens: A slight negative pressure is supplied to the common chamber 11, but not enough to raise the piston It is. The control system sends an electrical pulse to valve 14. The armature or valve stem 22 is raised. O-ring 23 on valve stem 22 will seal against valve seat 24. Even after the solenoid or electromagnet has ceased to operate, the negative pressure above the O-ring 23 Holds the valve stem upwards. The pressure on the underside of the valve stem is almost atmospheric due to a small leak between the piston and the cylinder. Pressure. When a large vacuum (lifting vacuum) is applied, the valve in question is kept down Meanwhile, the other valves are raised.   To reset the system, a positive pressure is applied to the common chamber 11 and the valve stem 2 2 is lowered and valve 14 is opened.
