Description

 The invention relates to packaging equipment, in particular to devices for cutting laminated tape into individual paintings, and can be used in the food, textile and printing industries.

 A device for cutting tape material containing guides, a rocker with two clamps at its ends, a knife mounted near one of the clamps, and a material supply unit made in the form of a pusher with a carriage located between the clamps and connected to the drive. The beam is connected to the pusher by means of a ball stopper.

 The pusher is moved in the vertical direction by the drive. When moving down, the pusher carriage pulls a loop of material, and when moving up selects a loop, moving it to the knife. In this case, the clip located near the knife prevents the longitudinal displacement of the material when pulling the loop, and the other clip when sampling the loop.

 The known device cannot be used for cutting laminated tape into individual paintings. The reason for this is as follows.

 In the manufacture of laminated tape by pressing, paper blanks with the image are superimposed on the overlap film. When cutting such a ribbon into separate pictures, it is necessary to cut the film without damaging the paper blank, since the pictures are then knocked together on the right side of the paper blank, marked with special characters, for further cutting. In the known device, the film and paper are cut together and the correct side of the paper blank is violated.

 The objective of the invention was to create a device that allows you to cut the film of the laminated tape without damaging the paper.

 The problem is solved in that in the known device for cutting tape material containing guides, a rocker with a clamp at one end thereof, a knife installed near the clamp, and a material supply unit with a drive, according to the invention, the material supply unit is made in the form of a drum and interacting with him a roller mounted on the other end of the rocker arm with the possibility of rotation around its axis, under the guides mounted vertical wall with emphasis, the device is equipped with an additional clamp mounted with on the other side of the guides with the possibility of rotation in the vertical plane, a cap with a mesh in the lower part is placed above the guides, connected to an air pump for alternately pumping and sucking air, the beam, knife and additional clamp are equipped with actuators, and an end switch electrically connected to drive control unit and air pump.

 This design of the device allows for one cycle to feed the tape to the length of one workpiece, keeping it horizontal due to the air pump operating in the suction mode, then switch the air pump to the discharge mode and lower the tape to a vertical position, press the tape against the vertical wall and work surface table clamps and cut the tape along the cutting line. At the cutting position, the previous workpiece is pressed against the vertical wall, and the next one with the right side in front is horizontal and pressed against the working surface of the table. Thus, only a layer of film is on the cutting line, and the paper is not damaged during cutting.

 In FIG. 1 shows a device for cutting tape material, General view; in FIG. 2 same, plan view; in FIG. 3 node 1 in FIG. one; in FIG. 4 - knife, plan view.

 A device for cutting tape material comprises a table 1, on the working surface of which guides 2 are fixed. Using supports 3 on the table 1, a beam 4 is installed, made in the form of a frame.

 At one end of the rocker arm 4, a clamp 5 is fixed, and at the other end of the roller 6, which can rotate around its axis. Under the working surface of the table 1 there is a drum 7 connected to the drive 8. To ensure the interaction of the roller 6 with the drum 7, a window 9 is made in the working surface of the table 1. There is a gap “a” between the working surface of the table 1 and drum 7.

 Under the working surface of the table 1 near the clip 5 is installed a knife 10, the cutting edges of which form an obtuse angle. The knife 10 is equipped with a needle 11, the axis of symmetry of which coincides with the axis of symmetry of the knife 10.

 Table 1 is provided with a vertical wall 12 with a stop 13 placed under the guides 2.

 On the outer side of the guides 2 are mounted with the possibility of rotation in the vertical plane of the clamps 14.

 Above the guides 2 there is a cap 15 with a mesh 16 in the lower part, connected to the air pump 17.

 Rocker 4, knife 10 and clamps 14 have actuators 18 20, respectively. Actuators can be pneumatic, hydraulic or electric, such as solenoids.

 At the end of the guides 2, a limit switch 21 with a lever 22 is installed. The limit switch 21 is electrically connected to the control unit 23, designed to control the actuators 18 20 and the air pump 17.

 In front of table 1, a bobbin 24 with laminated tape 25 and an auxiliary drum 26 are placed. At table 1, under the guides 2, a trolley 27 is installed for cut pieces.

 The device operates as follows.

 The feed of the tape 25 is carried out by rolling it between the constantly rotating drum 7 and the roller 6. In this case, the clamp 5 is raised above the working surface of the table 1, the knife 10 is withdrawn from the cutting position, and the clamps 14 are withdrawn from the wall 12. The air pump 17 when feeding the tape 25 operates in air intake, and passing under the mesh 16, the tape 25 is held in the guides 2.

 When the edge of the tape 25 is in contact with the lever 22 of the limit switch 21, the control unit 23 issues commands to the actuators 18 20 and the air pump 17 in the following sequence.

 The drive 18 rotates the beam 4, while the roller 6 rises above the surface of the tape 25, and the clamp 5 is lowered on it. The feed of the tape is stopped due to the presence of a gap “a” between the working surface of the table 1 and the drum 7 (the tape does not touch the drum 7).

 The air pump 17 switches to air discharge mode. The tape 25 under the influence of a jet of air falls out of the guides and hangs vertically on the wall 12, resting on the emphasis 13.

 The actuators 20 rotate the clamps 14 in a vertical plane until they press the tape 25 against the wall 12. The previous workpiece is pressed against the wall 12, the next workpiece with the correct side 28 is pressed against the working surface of the table 1, and only the film layer is on the cutting line.

 The drive 19 moves the knife 10 to the cutting position, and the tape 25 is cut into blanks. In this case, the needle 11 first pierces the film, and then the cutting edges of the knife 10 cut it.

 After a predetermined time, the control unit 23 issues the next command to the actuators 18 20 and the air pump 17.

 The clamps 14 are retracted by the actuator 20 from the wall 12 and rotated to the initial position, the knife 10 is retracted by the actuator 19 from the cutting position, and the beam 4 is turned by the actuator 18 to the position where the clamp 5 is raised above the working surface of the table 1, and the roller 6 interacts with the drum 7 .

 Next, the cycle of the device is repeated.
