Description

I

This invention relates to the cold working of a strip material, for example cardboard, rubber, metal, etc. and can be used in devices for cutting blanks from strip material.

The known carriage to the device for cutting blanks of strip material containing a slab, in the slots of which resilient plates are arranged sequentially to move one relative to another, carrying the cutters and equipped with a mechanism for their movement, made in the form of a hinged arm connected at one end with one of the plates, and an emphasis mounted on the base of the device with the ability to interact with the free end of the two shoulders. The plates are made spring-loaded and installed in the grooves of the plate with the possibility of deflection in the direction of the cutters and are equipped with a bend mechanism made in the form of a roller mounted on the base of the device, alternately interacting with the plates on the side opposite to the arrangement of the cutters ij.

A disadvantage of the known carriage is the insufficient productivity of the process of cutting blanks, due to the fact that the cutters are located on one side and the cutting process is performed from one strip or tape by one side of the carriage. In addition, for cutting blanks from two strips or tapes, it is necessary to increase the dimensions of the carriage and make two double slide devices.

The purpose of the invention is to increase the productivity of the blanking process.

The goal is achieved by the fact that the plate is made of two parts, equipped with a shaft mounted on one of the parts, on which the other part is rigidly fixed, and a mechanism

The bracket 38 is spring-loaded in the vertical direction with a spring 181 and 5 provided with stops 182 and 183. On the bracket 57, two shoulders are hingedly attached to the levers 184.

The carriage and the device for cutting blanks of strip material work as follows.

First, the cassette is adjusted in accordance with the dimensions of the sheets 102 by means of a screw 153 and movement of the wall 173. Then the cassettes are turned on the column 107 to the side (to the right). In this case, the cassette slides along the platform 154, holding on to the screw 153. The table 103 under its own weight is lowered to its original lower position. Racks 130 in accordance with

sheet sizes are moved a predetermined distance along the groove 139 of the table 103, after loosening the screw 129. Then, a stack of sheets 102, such as a special card, is placed on the table 103 to a level that excludes the inclusion of the sensor 138. Then the cassette on the column 107 is rotated to its original position (FIG. 8), after which a stack of sheets 102 of soft material, for example, of leatherette, is placed on its bottom, and the screw 153 is alternately lowered or raised.

When the cassette is lowered, the movable wall 143 maintains a constant level by moving the rack 149, transmitting through the gear 148 to the rack 147 a similar movement in the opposite direction.

In this position, the lifting mechanism of the table 103 is in the initial position (Fig. 8). The lever 117 of the lifting mechanism under the action of its weight is lowered down. The spring-loaded rod 119 touches the lever 112. By turning the flywheel 109, the table 103 rises or falls and the stack of sheets moves relative to the spring-loaded stops 23 on the plates 1 and 2.

Plates 1 and 2 are located on brackets 32 in corresponding positions and slightly raised by the action of springs, which is necessary for the passage of the clamped sheet on plate 1 and plate 31 relative to the lower plates of presses 36 and 37. On plates 1 and 2 (Fig. 8) the lever 17 under the action of the spring of the lever 18, as well as the plate GO, are in the initial position, i.e. its plates are pressed against one another by an effort directed toward the spring-loaded stops 23.

The slides 160 and 167, together with the upper stop plates 159 and 166 with the stops fixed to them, are in ct. M. Under the action of the spring 181 (Fig. 5), the bracket 38 on the column 34 together with the stops 182 and 183 with the mechanisms 39 and 40 pushing up to the up position. The ejector 45 (Fig. 7) on the plates 41 under the action of the spring pressed down to its original position. In this case, all the heads of the pushers 45 touch the plate 41. The locking plate 46 is also in the initial position and pressed by the bolt 48, which cooperates with the stop 50, to the initial position. Under the action of the spring, the lever 48 holds the snap-in plate 46 in the indicated position. Thus, on two sections of the bracket 32 of the carriage are in the working area of the press 36 and 37 (Fig. 6), i.e. the plate 2 with its stop plane lies on the stop plane of the plate i, and on the remaining two sections of the bracket 32 the plates 1 and 2 are located in the area of tables 70 and 71 in the opened state (Fig. 5) and are installed at the same level in the horizontal plane. The carriage stops 30 interact with each other, which limits the lowering of the plate 2 relative to the plate 1 under its weight. The mechanism of rotation of the bracket 32 (Fig. U) is in the initial position. The lever 174 under its weight lowered to its original position, and the latch 176 enters the hole 180 on the bracket 32 and fixes the latter in the specified position. The mechanism (figs. 1 and 9) of the tables is in the initial position. One end of the lever 95 is lifted upward under the action of the spring 96 together with the thrust 101, with this the rod 24 is pressed forward by the spring, and the second end of the lever 25 opu 73210

schen down. The rod 97 of the hydraulic cylinder 98 together with the piston 99 is in the lower initial position. The toothed rack 89, by interacting with the gear 94, moves in the hollow body 86 of the turning mechanism to the far left position. Gear rails 87 and 88 are fixed by latches 66 and 67 on shafts 60 and 6 and remain stationary Mi-T gi 92 under the action of springs lifted upwards. In this case, the lugs 91 t g 92 are installed in the path of the movement of the levers 90, and both the thrusts 92 and the others do not touch the spring-loaded base fixedly, 5 pa 93.

Then, the sliders 160 and 167 of the presses 36 and 37 are set in motion, and they, together with the plates 139 and 166, of the wtm. begin to descend in the direction of the lower 2d 1СХ support plates 161 and 168.

At this point, two pairs of carriages on the bracket 32 are in the working area of the presses 36 and 37 in the folded position (Fig. 2 and 6). The remaining two pairs of carriages in the open position are located in the zone of the ejection mechanisms 39 and 40 together with the ready-cut products. The upper support plates 159 and I66 continue to fall for a predetermined distance, while the stop 162 on the plate 159 reaches the stop 182 on the bracket 38 and begins to act on it, spinning down, overcoming

5, the force of the return spring 181. Together with the brackets 38, the stop 183 fixed on it, which stops through the holes 180 (Fig. 5 and 10) on the bracket 32, reaches the thrust fOl (Fig. 5 and 9) and pushes it down. , carried out the cocking of the lever 95. Shifting down the ha 101, overcoming the force of the return spring 96 of the turning mechanism, pushes down

5, a double-shoulder lever 95, which rotates the associated gear 94 in the same direction. While meshed with the intermediate rack 89, the gear 94 moves it in the housing 86 of the rotation mechanism to its original position (Fig. 5 and 9). While the racks 87 and 88, which are located in the cavity of the intermediate rack 89, remain stationary, since the levers 90 are pressed

Claims (3)

5 from the toothed racks 87 and 88, which are engaged with the toothed gears 62 and 63. Upon further turning down the axis, the lever 95 11 reaches the installation zone of the clamp 9 acts on its stop 91 from above, and then the lever 95 is fixed by the lock 93. In the process of turning the lever 95, the associated rod 97 of the hydraulic cylinder 98 together with the piston 99 also lowers to the lower position. At the same time, valves 100 ensure free mixing of piston 99. Thus, the turning mechanism is cocked and ready for operation. The plugs 92 remain raised upward under the action of the spring and do not touch the latch 93. At the same time, at the moment of lowering the bracket 38, the mechanisms 39 and the extrusion AO are pushed down along with the ejector 45. A part of the ejector 45 mounted on the plates 41 enters the hole 7 at the same time on the plates 1 and 2, and then through the holes 21 and through the holes 14 into the cutters 13. Another part of the pushers 45, not meeting the holes on the plates 10, is easily pressed. At the indicated moment when the bracket 38 is lowered, the release lever 48. (Fig. 7) of the locking plate 41 interacts with the yftopoM 49. The locking plate 46 is moved to the working position and ejects which entered the registers with the heads. Next, the ejectors 45 reach the workpieces and push them onto the tables 69 and 70 simultaneously with the plates 1 and 2. Together with the plate 159 a guide 164 is lowered, which pivots the contact area of the lever 174 of the ratchet wheel 56 of the turning mechanism (Fig. 5 and 10). and then takes the starting position. In the process of lowering the plates 159 and 166, the stops reach the levers 26 and the levers 25. One sheet remains free to lie on the cutters 13 on the plate 2, and the swarm sheet after the turn of the levers 25 rests on the lower plates 161 and 168. At the indicated moment The plates 159 and 166 reach (Fig. 5) the sheets lying on the plates 1, and begin to put pressure on them both the plates 1 and 2, lightly go down. At the same time, the cutters 13 on the plates 2 touch the sheets 102 lying on the lower plates 161 and 168. Thus, due to the force of the upper plates 159 and 166, the cutting of the individual sheets on the plates 1 and 2 is carried out by means of the cutters 13. 1 waste first. 12 in the form of individual particles (since the cutters are tightly installed) remain between the cutters 13. The blanks enter the cavities of the cutters 13. After the cut is finished on the plates 1, the cutters 13 are lowered under the force of the upper plates 159 and 166 and set at the level of the stop plates 22, which in the future, take on the efforts of the upper plates 159 and 166, eliminating excessive pressure on the cutters. Thus, the upper abutment plates 159 and 166 carry out cutting of more rigid material with cutters. After cutting the sheet blanks on the plates 1 (in order to also eliminate excessive pressure on the cutters), the latter, also with the plates 10, are slightly squeezed out and become level with the strips 22 on the plates 1, eliminating further excessive pressure (for example, during hydraulic action) of the upper stop plates through plates 2 on the cutters: 13. Slides 160 and 167, together with the upper plates 159 and 166, reach the m. and do not stop camping start moving up. Under the action of the spring 181, the bracket 38 begins to rise up together with the pushing mechanisms 39 and 40, and the ejectors 45 exit from the openings of the cutters 13 and the plates 1 and 2, which are deployed in the area of the tables 69 and 70. Together with this, under the press 36 and 37 plates I and 2 are slightly raised. At this point, the bracket 38 in place, with stops 181 and 183, reaches the upper position on column 34. At the same time, at the moment of lifting the bracket 38 and the upper plates 159 and 166, on the bracket 38, the stop 181 separates from the spring loaded pull 101 (FIG. 9) table rotation mechanism. At the same time, the dog-stop 162 (Fig. 5 and 10) on the plate 159 touches the lever 175 and the mechanism of rotation of the bracket 38 at the bottom and, overcoming the force of the return spring 181, removes the retainer 176 connected to the lever 175 from the holes. The stop 163 touches the bottom of the lever 174 of the ratchet wheel 56 of the turning mechanism and begins to lift it. Turning the lever 174 rotates the ratchet wheel 56 together with the shaft 55 to the bevel gear 53, which, being engaged with the second bevel gear 51 mounted on the column 34, begins to turn the bracket 32 in the direction of travel (counterclockwise). Thus, the bracket 38, together with the plates 1 and 2, begins to rotate, while the release arms 77 (Fig. 5 and 9) act on the levers 84, which, when turned, act on the levers (Fig. II) of the table lifting mechanism 69 and 70. Under the action of a spring mounted on the lever 77, the spring-loaded rod 95 is pressed down, from which the pawl 78 on the lever 77 engages with the teeth of the ratchet wheel 76. The electromagnet 82 is turned on, which, due to the spring-loaded lever 81, weakens the brake tape 80 at the time of turning the gear 79 paired with snoring The new wheel 76, which, in turn, meshes with the teeth of the stem rod 74, moves it together with the tables 69 and 70 downward by a predetermined distance (by the thickness of the sheet to be cut). After that, the electromagnet 82 is turned off, and the levers 81 under the action of the spring 83 due to the tension of the brake band 80 hold the shaft 75 and the tables 69 and 70 away from the shaft. The levers 77 of the ratchet wheel 76 are lowered to their original position. At the moment of rotation of the bracket 32, at the same time, two pairs of carriages emerge from under the presses 36 and 37, and accordingly two pairs of second carriages, in unfolded form, exit from the zone of the pushing mechanisms 39 and 40. At the moment when the carriages begin to walk from the working area of the presses, the spring-loaded strips 31 mounted on the plates 1 remove from the plates 161 and 16 a part of the waste. When two pairs of carriages simultaneously begin to emerge from under the presses, and accordingly two second pairs of carriages exit from under the pushing mechanisms 39 and 40, the levers 6 reach, respectively, the stops 157 and 158 and the plate 2, on which the blanks are cut. While the stops 30 (Fig. 2) limit the rotation of the plate 2 relative to the plate 1. The carriages that are extruded from the area of the pushing mechanisms 39 and 40 by the lever 6 and the stop 49 (Fig. 6) are turned from the unfolded position to the working position. Upon further rotation of the brackets 32 in the indicated direction, respectively, two pairs of carriages, on which the cutting was carried out, already in the expanded form, i.e. cutters facing down on. step into the area of mechanisms 39 and 40 3214. ejection, and the two two pairs of carriages, which were pushed out of the ejection area of the finished products, assume the working position, i.e. the plates 2 lie down after turning to the support planes of the plates 1 with the cutters 13 upwards; In the indicated position, in the process of rotation of the bracket 32, two pairs of carriages enter the loading zone, and the second pairs of carriages continue to flow into the ejection zone of finished products, i.e. in the area of tables 69 and 70. At the indicated time, the carriages that entered the loading area, due to spring-loaded lugs 23 installed at the back of the plates, simultaneously set the number of sheets 102 from the cassette and from the table 103. the front end begins to rest on the cutters 13 of the plates 2, and the sheets 102 advanced at this time from the tables 103 immediately enter the guide plate 134. At the indicated moment the levers 26 reach the stop bar 136 mounted on the plate 134 and interact with it, from which the levers 26 begin to rotate, and then under the action of a double action spring, the sheets 102 are pressed simultaneously on the plates 1 and 2. The levers 25 on the plate 2 pass through the slots 135 on the guide plate 134. The carriages in the indicated position continue to move with the clamped blanks. Together, with this on plates 1 and 2, which in expanded form enter the zone of the pusher mechanisms, an automatic spontaneous discharge of waste takes place in the area between the bases of the press and the mechanisms of ejection. For this, in the process of moving the carriages in the indicated position, the levers 17 alternately interact first with the plate 2 and then with the plate 1 and due to the tension of the plate 15 and turning the disks 16 of the plate 10 of the cutters 13 are consumed. The waste, located between them in the form of separate particles, is freely supplied to the adan site (Fig. 5). At the specified time, the heads in the T-shaped pairs 11 of the rods 12 have the possibility of a parental movement. The rollers 19, mounted on the plates 10 sequentially in the process of turning the arm 38, reach the stop 163. and interact with it. The plate 10, resting against its opposite end of the wall of the groove 9, is pressed down. 15 The tightly mounted cutters 13 are consumed, and the departing ones located between them are freely fed to the portion indicated above. In this case, the levers 17 continue to contact plates 1 and 2. After the waste dumping is completed, lever 17 ceases to act with plates 1 and 2, from which, under the action of a spring, the spring-loaded lever 18 on the carriages returns plates 10 to the initial position until the cutters 13 touch each other with a friend (Fig. 7). Thus, in the process of further rotation of the carriage bracket, which are in the loading zone, the installation zone of the cassette and the table 103 passes, while the sheets on the underside of the stack of sheets of the cassette lie on the cutters 13 of plate 2 and touch the spring-loaded lugs 23, the sheets 102, which are pressed by the levers 25 from the front end on the plate 1, arrive at the opposite end on the guide plate 134, where the lever 26 presses these sheets from the bottom of the rear part of the carriage to the cutters, passes through the groove 135. At the indicated moment the lever 26 (Fig. 8) on the interaction carriage It runs with rollers 124 per leg 123, which begins to act on the spring-loaded rod 122 of the lever 117, which also begins to lift upwards. In so doing, an electromagnet 113 is turned on, which weakens the tension of the brake band 111 on the shaft. When the lever 117 interacts with the ratchet wheel 16, it is rotated in the counterclockwise direction. Being in engagement with gear 115, the ratchet wheel 116 lifts the table 103 until the top sheet 102 reaches the end of the lever 137, which communicates with the other arm with the sensor 138, which sends a signal to turn on the electromagnet 126, which unlocks in the sleeve 121 of the lever 117 relative to the rod 122. The electromagnet 113 is turned off. Under the action of the spring of the lever 112, the brake rod 111 tension is tightened, thereby ensuring that the table 10 is kept from lowering it. In doing so, the lever 117, overcoming the spring force on the spring-loaded rod 122, under its weight, lowers into the operating position. At the specified moment, the stop 29 on the plates 1 2 .. rotates the contact zone of the roller 124 of the lever 117. Thus, the supply of the next corresponding pairs of carriages for the press with the sheets 102 laid on them is completed, as well as the supply of the corresponding pairs of carriages in the unfolded position at cut blanks that are planted in the cutters 13 into the zone of the pushing mechanisms 39 and 40 to remove and push them onto the tables 69 and 70. When one of the tables, for example table 70 (Fig. 9), is lowered to a predetermined height, the table has its lower side acts on tgu 92, which goes down, overcoming the force of the return spring of the stop 92, rotates the levers 90 towards the locking groove on the toothed rack 88. The heat ha 92 interacts with the lock 93, from which the latter, overcoming the force of the return spring, moves away from the lever 95, which is under the action of the spring 96 begins to lift up, turning gear 94, which, being engaged with intermediate rack 89, moves it to the right position. In this case, the rack and pinion 88, fixed by the levers 90, also moves in this direction and, being in engagement with the gear 63, rotates it. The toothed rack 87 remains stationary in the cavity of the moving intermediate toothed rack 89, since the corresponding lever 90 at the opposite end is raised by the abutment 92. Thus, when lifting the lever 95 under the action of the spring 96, the shaft 61 is simultaneously rotated with the plate 65. Piston 99 begins to move down. The valve 100 in this direction limits the capacity of the fluid and the piston 99 smoothly at a predetermined speed moves the lever 95, and at the same time carries out a smooth rotation of the plate 65 by 180 (Fig. 9). The plate 64 is rotated in a similar manner. Table 69 is lowered in the process of laying the blanks 72 thereon at a predetermined portion. In a similar way, by means of two toothed racks 87 and 88, simultaneous rotation of the tables 68 and 69 on the plate 65 is carried out. Thus, after completing the rotation of the plate 65 as indicated above, the stack of blanks 72 is removed and the table 7), which occupied the position of the table 70 , continues to take on the workpiece 72. The lever 77 of the lifting mechanism becomes under the corresponding stop 91. When the workpiece 72 is removed from the table 70, the electromagnet 82 is turned on at the time of its turn (fig. 11) and the rod 74 raises under the action of the spring 84 in the upper position. The electromagnet 82 is turned off. The brake on the belt 80 keeps the table from spontaneously lowering it. Table 70 is again ready to receive workpieces 72. Claim 1.
