Definitions
- the present invention relates to a process and apparatus for making and filling a series of bags, in which a strip of material folded lengthwise and divided into a number of compartments by transverse seams, is conveyed past a filling device with its open side upwards, and after filling closed on this side (see Netherlands patent specification No. 53,211).
- the present invention provides a process and apparatus in which the bags under the filling device are opened sufficiently wide to be filled completely.
- the present invention is based upon the principle that, when the strip is moving under the filling device, that part of it which has just passed the device is stopped when a bag that has to be filled is directly under the filling device, while the part just arriving in front of the device is moved on until the walls of the bag fold, so that they can be moved apart, after which the bag is filled and subsequently first that part of the bag which has passed the filling device is set moving again, so that the open side of the bag is closed by the pull exerted on the walls, and then the part behind the filling device is set moving, whereafter the motion is continued until the next bag has arrived under the filling device, and so forth.
- the bag folding under the filling device its walls can easily be separated, for instance, by means of a wedge or a similar member inserted between the walls at the top, which member may be connected to an air feed line for blowing open the bag, which at its upper end has already been partly opened by the wedge.
- the bag may be opened by means of suction pads placed on the outside of the walls and then moved apart.
- the device for filling the bags is preferably equipped with two sets of rollers or belts, provided on both sides of the device, which retain the strip at the top, while means are provided for intermittently driving the rollers so that the rollers behind the filling device are stopped and set moving again slightly earlier than the rollers provided in front of the filling device.
- FIGURE 1 is a side elevational view of an apparatus embodying the principles of the present invention
- FIGURE 2 is a top plan view of the apparatus.
- FIGURE 3 is an enlarged fragmentary perspective view of the apparatus.
- plastic film 1 in tubular shape which is ice v between the walls of the film at this upper edge.
- the film then passes between two belts 9 and 9' which grip the film near its upper edge.
- the belts are trained about rollers 10-11 and 1011', respectively, which, each time a compartment has been filled move on the film so far that the following compartment arrives under the filling device 12.
- a closure or grooved rotary metering device 19, provided under the filling device 12, is now opened or put into operation, respectively, so that the material to be filled into the bags flows into the compartment.
- the air supply through the conduit 17 and the vacuum in the suction pads 18 may be interrupted, since then the compartment is opened wider owing to the weight of the material.
- the belts 13 and 13' are again set in motion. As the belts 9 and 9 still retain the film, the top edge of the film is stretched, so that here the walls of the compartment come to lie against each other. Thereafter the belts 9 and 9' are also set moving.
- the fil-m subsequently passes a welding device 20, which closes the top edge of the bags.
- the closure weld 21 connects to the side welds 5, so that the compartment is closed all round.
- the filled compartments are cut off by a knife 22, so that filled and closed bags 23 are obtained.
- the invention may be employed for filling bags with powdery or granular materials, such as plastic granulates, fertilizers, cement, animal feeds, etc.
- the bags may measure, for instance, 50 x cm., and may be made of polyethylene film having a thickness of 0.2 mm.
- the weld 5 should be wide, or two welds should be made side by side. If desired, the weld 5 may be perforated or incised, so that the filled compartments can be torn 011?, instead of cut loose after they have been closed by welding.
- the bags may be made of homopolymeric or of copolymeric polyalkenes, polyvinyl chloride, etc., or of mixtures of these substances, whether or not reinforced with fibrous materials, for instance rayon, glass fibres, nylon, etc.
- the plastic material from which the bags are to be made is preferably provided with an imprint.
- a mark 24 is provided in a suitable position on each compartment which interrupts a ray of light or an infra-red ray from an emitter 27 when a compartment has arrived under the filling device, so that a cooperating receiver 28 gives an impulse for stopping the belts 13 and 13.
- a photoelectric or infra-red cell emitter 25 and receiver 26 giving an impulse when a compartment has been filled, so that the feed is stopped and the drive of belts 13 and 13' is switched on.
- a timing relay a drive to the belts 9 and 9' may then be set in motion slightly later.
- the belts 13 and 13' are provided with a drive such as electric motor 29 and cooperating gears and 30.
- a drive such as electric motor 29 and cooperating gears and 30.
- the belts 9 and 9' will, owing to inertia, continue their motion for a moment, until the desired folding of the compartment under the filling device has been effected.
- the rollers of these belts may, to this end, be constructed as flywheels, or be provided with a flywheel, while a braking device may be installed for preventing these belts from running on too far.
- FIGURE 3 illustrates schematically one arrangement for effecting the operation of the belts 13 and 13 and the metering device 19 in response to the movement of a compartment under the filling device 12, the filling of the compartment by the filling device 12, and the subsequent operation of the belts 13 to move the next compartment under the filling device.
- the receiver 28 is of a type arranged to transmit an impulse or electrical signal when the light beam from the emitter 27 is interrupted by the movement of a mark 24 into the path of the beam.
- the receiver 28 is electrically connected to turn off the motor 29 driving the belts 13 and 13 and to turn on a motor 31, or other operating mechanism, connected to the metering rotor 19 or other dumping mechanism.
- the electrical connection to the motor 29 and motor 31 is such that a single impulse will effect the continuous energization or de-energization of the respective motor all in a known manner.
- the receiver 26 is connected to the motors 29 and 31 so that a single impulse or electrical signal is transmitted when the level of the material in the compartment being filled interrupts the beam transmitted by the cooperating emitter 25.
- the impulse or sigv nal from the receiver 26 is electrically connected to turn on the motor 29 and to turn off the motor 31.
- the electrical connection is such that a single impulse will effect a continuous de-energization or energization until such time as a new signal is received from the receiver 28.
- the remaining operating mechanisms of the entire apparatus can, likewise, be connected to perform their operation in response to the signals generated by the receivers 26 and 28.
- the filling devices 4 and 20, the air injection tube, suction pad 18, conveyor 16 and cutting device 22 can all be suitably arranged to be actuated in response to a signal from the receiver 28.
- the actuation of these operating devices in response to the electrical signals from the receivers 26 and 28 may be in accordance with conventional practices utilizing time delay relays and other wellknown components to effect the desired timed sequence of events.
