Description

INTERIOR WARDENING MACHINE FOR PACKAGING TECHNICAL FIELD The present invention falls within the technical field of mechanics, since it is a machine for arming interiors or "cushion", which are placed inside a box or package to hold and protect the objects that are stored and transported in their inside.

BACKGROUND The boxes are one of the most used means for packaging and packaging a wide range of products in most areas of industry, this due to the many advantages they have, such as content protection during transport and storage, identification and image, economy, as well as its recyclable and recycled nature.

In its elaboration, it is used mainly corrugated cardboard, which is a structure formed by a central rib of corrugated paper, reinforced externally by two layers of paper glued with adhesive on the crests of the wave. Due to its composition, corrugated cardboard can be corrugated on one side, single corrugated, double corrugated and triple corrugated.

The packaging, storage, transport, distribution and use by end users are the main stages through which a box passes to reach its destination. Therefore, the demands placed on a box to maintain its strength are very high, due to constant handling, and special attention must be paid, among others, to the grammage of paper or cardboard by surface area, humidity, thickness of the cardboard and test Of compression.

As mentioned above, corrugated cardboard boxes are required for a wide range of products, ranging from fresh fruits and vegetables, manufactured products, household appliances, industrial machinery, to semi-trailer transportation of products in drawers or hoppers. They adapt easily and equally to all modes of transport, whether by land, sea or air.

At present, several machines and methods are known to facilitate the process of assembling boxes and packaging. There are automatic and semiautomatic machines for setting, sealing and closing of boxes, which assemble and seal the boxes with adhesive tape, "hot melt" or staples. For example, the international document PCT / IL2010 / 000906 describes a continuous production line for manufacturing folding boxes. National document 9602739 discloses an assembly and method for assembling cardboard boxes, for use in continuous motion packing machines, to perform specific functions in a cardboard box, as it moves continuously along the travel path through the carton. the packing machine.

However, some products such as household appliances and electronic equipment, among others, require protection greater than that provided by the box or packaging, for example, to avoid unforeseen movements inside these containers, caused by their handling or transportation, which can deteriorate the product. To avoid this situation, fastening structures have been designed that are placed inside the boxes, known as interiors or "cushion", which have the function of holding and protecting the contents that are stored inside the boxes. However, in the state of the art no specialized machines are described to automate the process of interior assembly or "cushion" for boxes.

OBJECT OF THE INVENTION The present invention proposes an automatic machine to arm interior or "cushion" to be used inside boxes or packaging, in order to hold and protect the objects that are stored and transported inside. The interiors or "cushion" are clamping structures made of corrugated cardboard that are placed inside the boxes, to avoid unforeseen movements inside these containers, caused by their handling or transport, which may lead to deterioration of the contents.

Supplies - Electric power: 220 volts alternating current, three phases, 60 hertz, 10 amperes.

- Air: Supply pressure 6.0 Kg / Cm2, 150 LJMin.

- Crew: Three people.

Ignition of the machine 1. Connect the compressed air supply. 2. Connect the power supply. 3. Close the main switch. 4. Start the drive chain drive motor.

Start of operation of the machine To start the assembly it is required that the "cushion" be preformed, squared and have introduced the longer fins that go in the bottom of the headers of the "cushion", these are the first fins, this operation is done manually by the operator. The next step is to place the "cushion" in the correct position, that is, next to the pusher fingers (Arreadores) and in front of the arms of the first pneumatic actuator. The second step is to press the start button of the assembly cycle, so that the pneumatic actuator is activated by the supply of compressed air, which will provide an electrovalve for the bending of the second fin, which in this case would be the first that bends mechanically. Once the second fin assembly cycle is completed, a magnetic sensor activates a second pneumatic solenoid valve to supply compressed air to the number one cylinder that causes the pushers to move and these move the cushion forward, to leave it in position for that the draggers of the drag chain transport it to the second point of armed, where the fold of the third and fourth fin is made.

When positioning the "cushion" at the second reinforcing point or assembly station, a photoelectric sensor detects that the "cushion" is in the armed position and a second magnetic sensor detects that the actuator has stopped pushing the "cushion", at that precise moment a solenoid valve is activated to supply the compressed air to the pneumatic actuator that makes the bend of the third flap, when returning the pneumatic actuator to its "out" position, a magnetic sensor gives the signal for an electrovalve to give way to the supply of compressed air, so that a pneumatic actuator activates and performs the folding of the fourth flap. Upon returning the actuator to its "out" position, a magnetic sensor is energized to energize the solenoid valve to supply compressed air to the pneumatic actuator number two to activate and perform a final securing thrust, to confirm that the number four fin it has been fully inserted and a tab that serves as padlock for this fin has also been inserted into the corresponding slot. When the pneumatic actuator returns to its "out" position, it activates a magnetic sensor which energizes a solenoid valve to supply compressed air to a pneumatic cylinder number two, so that it pushes the "cushion" forward and removes it from this assembly station and Expel it as a finished product.

As soon as this pneumatic cylinder moves completely, a magnetic sensor is activated which sends a reset signal to the assembly cycle of the second station, leaving the system ready to start another assembly cycle in this station in the case that the initial conditions of a "cushion" in the armed position are met, and that the chain pusher has been detected by the magnetic sensor that has stopped pushing the "cushion", and thus the cycles are repeated again with a maximum frequency of 15 cycles per minute.

In the control system of the operation of the solenoid valves and the pneumatic actuators, magnetic sensors, photoelectric sensors, relays and timers with delay on and off; The operating voltage of these devices is 110 volts alternating current at 60 hertz.

This machine has an assembly capacity of 900 pieces per hour, if the operator that feeds it with the "cushion" has enough skill. The crew for the machine is three people, the first person is required to square the "cushion" and fold the number one fin; the second to feed the machine with the "cushion" placing it in the first assembly station; and the third to receive and stow the "cushion" with the fins fully armed.
