Description

The present invention relates to devices for the purpose of registering the operation of machine tools. In the above-mentioned device, for the accomplishment of this purpose, three electromagnets are applied, excited, with appropriate switching, every minute by closing the current using a clock mechanism. One of these electromagnets is used to move half-blackened ribbons in the cut-outs of the top cover, which has a time stamp along the cut-out edge; the second electromagnet serves to switch the course of the counters, one - taking into account the time of actual operation of the machine and the other - taking into account the time simply because of refueling, tool change / etc .; the third electromagnet controls the movement of the belt against the pick-up device in order to mark the time of the machine's repair in the event of a breakdown, etc.

In the schematic drawing of FIG. 1 is a front view of the device; FIG. 2 is a vertical longitudinal section of it; FIG. 3, 3, 4, 5, 5-separate parts of the device.

The device for registering the operation of the machines consists of three electromagnets (//, //, ///) installed in the box. 4, the measles of which are appropriately connected with counting mechanisms. The electromagnet / is provided with a crust fixed on the plate 2, which moves in the slit-like holes of the pillars 3, 4. The plate | 2 is provided with a release spring 5

and carries dogs 6, ba, coupled with the gears 7, 7 counters 8, 8, and lever 9, worn at one end on the roller 10. Mentioned lever 9 carries the dog 11, coupled with the gear 12. On the pulleys 13, 13a, 136, 3c, 14g, mounted on a common roller for them 10. Pulleys 13, 13a, 136, 13c. 13z, with the help of endless belts 15, 15a, 156, 15v, 15g, are connected with pulleys 16, 1б, 166, 1бб, 16i, located in the lower part of the box. Half tape length

15, 15a is painted black.

The electromagnet // is provided with a double arm 17, swinging on the axis 18 of a rack 4 (Figs. 1, 2 and 4), one arm of which is pulled away by a spring 19. In addition, both ends of the core 17 are equipped with rods 21, 21a with curved ends covering 6 6a in front of the dog. Electromagnet III has a bark 22, equipped with a pull 23, carrying a link lever 27 hinged to it, equipped with a writing device 29. T ha 23 carries a pawl 30 coupled to the gear 31 on the tongue 32; the latter is connected to an endless belt 33 with a pulley 34 mounted loosely on a roller 42. The belt 33 has divisions indicating periods of time. An anchor 22 is connected to a lever 35 carrying a conversion plug 36, 37, sliding in a recess 45 of a gear coupling 40 ,. a tube 44 mounted on a roller 42. A chat tooth, a coupling 40 rotating from a separate mechanism, engages a gear

The coupling 41 is mounted on the roller 42 of the pulley 34. The anchor 22 is driven down by the spring 43. The cover B of Chic A, against each of the two counts, has four windows corresponding to the discs of units, tens, hundreds and thousands of meters, and against each of the endless ribbons 15, 15y, 156, 15b, 15g, in the same lid there are slit-like openings 38, 38a, 38, 38b, 38g, fitted along the edges with time markings.

At the bottom of the box are pockets 39, 39a, 396, 39b, 392, and in the upper part there is a window 47 for a signal lamp 65. Under the counters in the opening of the lid, the lever buttons 48, 48a, 486, 48b, 482 are missing The levers of which are provided with notches 49, 50 and thrust pins 51, 52, 53. The signal lamp 55 installed inside the crate lights simultaneously with the action of the electromagnet /// and the associated mechanism (Figs. 1 and 2).

FIG. 3 shows the electrical circuit diagram of the device. When the machine B is turned on, contact 56 is closed, and when turned off, contact 57; wire 58 from a lever, wiring or other switch; its machine devices go through a switch 59 to an electromagnet /, the same wire 58 from contact 56 and 57 to contact mechanism G, to clip 59 (Fig. 4), and from clip 60 to the same electromagnet. From pin 61, wire 62 leads to an electromagnet // (figs. 3 and 4).

The disk device D consists of a series of similar devices located on a common shaft 63, each of which consists of interconnected: 1) disc 64 of an insulating material, equipped with contact plates 65, 66, electrically interconnected between themselves, 2) typical disc 67 with a conditional number of cuts and 3) a pulley 6B with a chute for the skin of the load 69.

Before starting the machine, the electrical part of the recording device is turned off and its individual parts are arranged as shown in FIG. 3: pin 70 is inserted into the hole of the disk 64, contact 12 is on the insulated part of the same disk 64, contact 72 is on the isolated part of the same

the disk 64, the contact 73 on the plate 65, the contact 74 in the first cut-out of the disk 67, the contact screw 75 does not touch the plate 76.

To warn you quickly. The device described above, under the action of the load 69, is supplied with an anchor descent. Contact 72 via wire 77 is connected to wire 58, and contact 73 via wire 78 leads to switch 59, which can be connected to line 58 either the machine or the disk device D, B, circuit 77.78 just turned on. schA s at the machine.

The contact device G consists of a clock mechanism with a gear disk 80, pivoting on the axis 81, into the teeth of which a lever 82 falls, the other end of which closes contact 83 at this time.

At the beginning of the machine operation, the central control station turns on the electric current into the device network, simultaneously turning on the clock mechanism of the contact device G, as a result of which every minute the lever 82, west of the teeth of the disk 80, closes through contact 83 the circuit of the electromagnet 7, which will periodically pull its measles 1 If the machine is on, i.e. The circuit of wires 56 and 58 is closed, then the dog 6a (Figures 4 and 2), coupled with the counter teeth 7a of the counter 8, will activate the latter, and the dog 11 will move the tape 15. When the machine is stopped for any auxiliary manipulations, as for example, to change or change a cutter, etc., as a result of switching the contact mechanism, the counter that takes into account the operation of the machine will stop, and another counter 8 will work instead of it, recording the time simply because before the circuit of wires 58, 57 is closed , the line 61, 62 will close, at which // om magnet attracted to itself measles no 17 and 21a sterzhenek Ott no dog 6 and Pin 21 will lower and the dog will include 6 serving counter, consider the time is simple. The lever 9 at the same time will work as before and, therefore, with each movement of the core 1. the tape 15 will move. When turning the machine into operation, the reverse occurs, i.e. line 61, 62 is disconnected.

spring 19 there is no bark 17, a rod 21 will interlock a ba-sling with a counter tooth 7a, which takes into account the operation time of the machine, and a rod 21 will turn off the pawl 7, which takes time into account simply.

Thus, one counter takes into account the time of the machine, and the other - its time is simple. In order to take into account an unforeseen machine tool, for example, due to a breakdown, switch 59 and pull the pin 70 of the corresponding disk 64, which can conditionally be called a “disc simply because of a breakdown. When this happens, the following will happen: the released disk 64 under the action of the load 69, will begin to slowly rotate in the direction shown by the arrow; while the first prong of a typical disk 67 will lift the contact 74 of the plate 76, connect it to the contact 75 and close the electromagnet circuit /// through the switch 59. When contact 74 falls into the depression between the teeth of a typical disk 67, contact 75 will open, and, in the cold, and turn off the electromagnet /// circuit. Such periodic closures and openings of this chain will occur until disk 64 reaches hole 85 to pin 70, which, under the action of spring 86, enters it and stops the disk. At this moment, the contact 72, which still slid along the insulation, will appear on the plate 66, the contact 73, as if it did not leave the plate 65, will remain on it, and the contact 74 of the plate 76 that has fallen into the last gap of the disk 67 will open with the contact 75.

During the above closures and openings of the electromagnet /// circuit, the measles 22 of the latter will be attracted and lowered as many times. During each pull-in of the core 22, the levervod fork 36, 37 will each time with the help of gear couplings 40, 41 interlock the rotating tube 44 with the pulley 34, and the latter, rotating, will move the tape 33 on which it acts each attraction of the core 22 to the electromagnet ///, the writing device 29 will make 33 marks on the tape, corresponding to the number and shape of the teeth of the typical disk 67. As soon as the pin 70

will stop the rotation of the disk 67, i.e. when contact 74 drops to the last neckline. therefore, contacts 74 and 75 will open, but contact 72 will no longer be on the isolated part of disk 64, but on plate 66, then the following will happen: line 76, 81a will be disconnected from the electromagnet ///, but it will turn out to be the previous 73 , 78, 59, 80 (to the 1P electromagnet) VL LINE 72, 77, 58 (to the contact mechanism D), the latter, in turn, connected to the same electromagnet III). From this point on, the connection of the rotating tube 44 with the coupling 41, 40 with the pulley 34 and the writing device 29 will not take place through the circuit through the standard disk 67, but every minute with the contact device G driven by the clock mechanism. Thus, when the machine is inactive, i.e. when turning the switch 59, first on the ribbon 33, due to the action of the typical disk 67 and the writing device 29. In the hardware (in this case) there are three short lines and a long dash, which conditionally means “simple due to a machine breakage, then the points will follow ; the number of divisions that these points will take will speak about time simply.

To register the time simply caused by any other reasons, for example, the absence of a tool and so on, is freed by removing the pin 70, the corresponding disk 64 with the conditional number of teeth on the sample disk 67.
