Description

Packing machine

The utility model relates to the field of packing equipment, in particular to the design of vertical packaging machines for packing loose, granular and other substances into packages of heat-sealable materials. The main criteria for packaging technology are reliability, dosing accuracy and ease of use.

A known design of a vertical packaging machine, containing an electric drive, from which a dispenser, a device for sealing and cutting off packages, a device for winding sealed packages, a device for regulating and correcting the length of the package, a device for controlling the speed of the packaging process is a friction type variator.

The mechanism for scrolling packages along the length includes a photoelectric sensor for reading labels from the packaging material, drive rollers for scrolling the package - the active and pressure drive cam, gear rotation from the intermediate shaft to the roller shaft, a coupling for turning on the rotation of the roller shaft, a device for regulating and correcting the length of the package. The drive roller for the winding of sealed packages by the size of one package receives rotation from the drive cam through gears on a pair that includes a clutch receiving a start signal from the photosensor. The machine is also equipped with a device for the current account of manufactured products - a packet counter.

The disadvantages of this design of electromechanical regulation and correction of the length of the package should include the complexity of the design: the design allows you to configure the length of the package by an amount less than a given value, therefore, after a certain number of measured packets, determined by the label width and characteristic

JJx / h- ./V/ photosensor, carry out a correction of the scroll in the originally configured

position. In addition, with each change in packaging material, it is necessary to reconfigure the length of the package in commissioning mode with the consumption of packaging material.

It should also be noted the following disadvantages of controlling the speed of the packaging process using a variator: a limited range of regulation of the rotational speed of the electric motor at a constant moment on the shaft, a limitation on the magnitude of the transmitted moment, a significant duration of the process of regulating the rotational speed, an additional overall size, due to the adjusting device, the variator design is not allows remote control of the speed, therefore, the design of the machine must be provided convenient access to the working unit of the electric motor-variator.

The disadvantage of the packet counter is limited functionality, i.e. the impossibility of fixing the fact of production of a certain number of units of production, which is varied as necessary by the operator.

The problem to which the claimed utility model is directed is to ensure the reliability and accuracy of the device for winding sealed bags according to the control mark on the packaging material, to simplify the design of the device, expand the functionality and range of regulation of machine performance and ensure ease of use.

To solve the problem, the drive roller for the winding of sealed packages is rotated from a separate electric drive by the size of one package, the signal for turning on the electric drive comes from the induction position sensor of the knives and sealing elements, and it is turned off automatically upon winding of the packaging material to the length of one package according to the photosensor signal . Reconfiguration to a different, greater or shorter package length provides an electric drive

automatically according to the check mark, it is only necessary to change the position of the photosensor depending on the required packet length.

The invention is illustrated in the drawing, in which: figure 1 presents a kinematic diagram; FIG. 2 (FIG. 3 embodiment) is a block diagram of an electric drive for the dosing, packaging and winding path of a packaging machine.

The kinematic diagram shows: 1 - the dispenser, 2 - the cam-setter, 3 - the induction sensor, 4 - the gear pair, 5 - the drive cams of the sealing device, 6 - the gear motor of the drive rolls of the bag winding, 7 - the gear motor of the dispenser drive and a sealing device, 8 — knives, bag cutters, 9 — rolls for wrapping packages, 10 a sealing device, 11 — a shaper of a tube tube, 12 — a photoelectric sensor, 13 — a tape of packaging material. Block diagram of the electric drive of the machine, figure 2 contains:

-Two frequency converters 14 and 18;

-Three pulse shaper 15,16,17, which act on the corresponding frequency converters and are made according to the scheme with a differentiating chain and a single-shot;

product counter 20, assembled on magnetostrictive binary counters;

- for visual control, the account indicator 21 is made on seven-segment LED indicators and monitors the current value of the finished product;

-the number of packets 22, assembled on decade switches and sets the number of packets in the technological batch;

Comparison device 19, implemented on logical digital elements, can be formed using digital camera microchips, and acts to stop the cycle with a preliminary warning signal or without it.

In the structural diagram of the electric drive, the winding channel of the packaging material (induction sensor - optocoupler triac motor-reducer) and the channel for automatically controlling and maintaining the temperature of the sealing device are not shown.

On Fig.3 presents a variant of the structural diagram of the electric drive of the machine with a microcontroller control system.

To start the operation of the machine, start the electric motor 7, driving the dispenser 1, the sealing elements 10 and the knives 8, on the shaft of which the cam-adjuster 2 is fixed. The cam is set so that its passage through the sensitivity zone causes the appearance of an electric signal at the induction output sensor 3 at the moment when the formed dose of product was spilled from the dispenser into the prepared bag. The signal of the induction sensor leads to the appearance of the “start-up (GS) start-up command in the form of a pulsed electrical signal at the output of the pulse shaper 15. The frequency converter 14, by the command“ GSH, drives the electric motor 6. The frequency of rotation of the electric motor 6 is controlled by the frequency inverter 14 and the operator sets it in advance setup process. The rotation of the electric motor leads to the winding of the tape. When winding the tape, the photosensor 12 is triggered according to the mark printed on the packaging material, the photosensor signal causes the “stop scrolling (SP)” command to appear in the form of a pulsed electrical signal at the output of the pulse shaper 16. At the same time, the photo sensor signals are input to the counter 20, the number of signals from the photosensor corresponds to the number of sealed and cut packets. The current value of the counted packets is displayed on indicator 21 for visual inspection. In addition, the current value is supplied to the comparator 19 comparator, where it is compared with a predetermined quantity of a dosed batch of products of the setter 22. When the counter reaches a predetermined value, the camcorder signal “reset resets the counter to zero.

j. / 7 If and also the signal is fed to the frequency converter 17 of the electric motor 7,

causing it to stop, or at a warning signal.

Link frequency converter - the electric motor provides reliable, accurate and accurate operation of the device for the promotion of sealed packages and dispenser, and also allows you to quickly and consistently change the performance of the machine.

The proposed design of the machine allows to ensure the reliability and accuracy of the device for winding sealed bags, simplify its design, expand the functionality and range of regulation of the performance of the machine and ensure ease of use.
