(54) SEMI-AUTOMATIC MACHINE FOR CUTTING THE TOP OF FOOT-FOOT POOLS

one

The invention relates to a flax-felt production shaft and can be used in the manufacture of shaft shoes.

A device for trimming the shaft shaft shoes is known, comprising a frame for clamping the shaft, a carriage and a disk knife 1.

A disadvantage of the known device is the necessity of manually inserting the tops of the boots to trim a predetermined length of the tops.

A known mask for trimming the top of the shaft of a shaft shoe, comprising a movable platform on which a size limiter is mounted, made in the form of a plan with a fixing screw moving in the transverse direction along the rod, a clamp that is a folding bar. When pruning, the tops of the pair of shoes placed on the platform in a direction transverse to the plane of the disk knife. The semi-pair rests under the base on the stopper, the top of the shoe is pressed by the clamp. The platform manually moves on the frames to the rotating disk knife, which cuts the top of the shaft 2.

A significant disadvantage of the known machine is the fact that the operations for determining the size of the shoe, its pressing and moving under the disk knife are performed manually, moreover, when the shoe size S is changed, the position of the limiter must be changed each time. All this leads to a loss of technological time.

Closest to the present invention is a semi-automatic top cutting machine, Q shaft of an axle shoe, containing, mounted on a frame, a rotary disk knife, a clamp located above the supporting table on the side of the circular knife, and a shoe size limiter, located on the other side of the anchor foot15 la 3.

A disadvantage of the known solution is the impossibility of using it for the whole growth-full assortment.

The purpose of the invention is the widening of the 2Q night shoe range.

 This goal is achieved by the fact that in a semiautomatic device the size guards are made in the form of hinged plates at one end, and the distance between two adjacent plates is equal to the difference of the lengths of the foot of two adjacent shoe numbers. FIG. 1 shows a semi-automatic, general view; Fig, 2 - diagram of the installation of shoes; FIG. 3 shows a section A-A in FIG. 2. A semiautomatic device for cutting the tops of the shaft shoe consists of an electric motor 1, kinematically connected by a chain transmission 2 to a single-turn clutch 3 of the camshaft 4, having cams 5 and 6. The single-turn clutch 3 by the thrust 7 is connected to the control lever 8. The camshaft 4 controls the clamp 9, which is designed as an abutment with a bristle fitted with a spring 10. The electric actuator 12 is fixed to the rocker arm 11, which is connected by a gear 13 with a disk knife 14. Inside the semi-automatic body to the panel 15, having dimensions 16, axis 17 is free limiters of 18 sizes are made in the form of hinged plates, each of which corresponds to a given size. The distance between two adjacent plates is equal to the difference in the length of the foot of two adjacent numbers of shoes. The support table 19 is located under the clamp and is provided with a motor control post 20, and the periodic sharpening of the disk knife 14 is carried out by a sharpening device 21. Semiautomatic works as follows. From the control station 20, the electric drive 1 and 12 are started up. From the electric drive 1, the clutch 3 receives the rotation through the chain drive 2, and the disk knife 14 receives the rotation from the electric drive 12 via the belt drive 13. To cut the shaft, a pair of shaft shoes is placed on the bearing table 19 in the direction transverse to the plane of the circular knife 14 under the clamp 9. In this case, the stops 18, which do not correspond to the specified size, deflect up to the stop on the panel 15, and the heel part abuts one of the stops 18, corresponding to the given shoe size. Then the lever 8 turns on a single-turn clutch 3 through the tug 7, transmitting the rotation to the camshaft 4. A cam 5 rotates on the shaft, which contacts the spring-loaded line with the stop 9, while pressing the shaft to the table. From the cam 6 through the transmission 13, the rocker arm 11 moves the circular blade 14 in the transverse direction. The leg is trimmed and the disk knife 14 is returned to its original position. The presser 9 is raised, freeing the bootleg. The trimmed pair is removed from the support table 19, on which the next pair is laid. If necessary, using the sharpening device 21 in the initial position, the knife is sharpened. 14. The use of the proposed semiautomatic device eliminates a number of manual operations when trimming the top of the shaft of the shaft shoe, which contributes to an increase in labor productivity. The semiautomatic device can be used most effectively in the flax-felt industry shaft. Claims of the invention Semi-automatic machine for cutting the tops of the shaft of a shaft shoe containing a rotating rotary disc knife fixed to the frame, a clamp located above the supporting table on the side of the circular knife and footwear size limiters placed on the other side of the supporting table, characterized in that the purpose of expanding the shoe growth range, the size limiters are made in the form of plates hinged by one end, the distance between two adjacent plates being equal to the difference in the length of the foot of two adjacent shoe numbers.
