    Automatic insertion machine for a new closure model, with an approximate Fermat spiral shape, in bags made of flexible materials that can be integrated into a production tape. The machine consists of several systems: A closure supply duct from an external hopper, a feeder that prepares the closures for use by the machine, a mechanism that tightens the part of the bag to be closed by narrowing the space occupied by it due to the mutual approach of some sheets that collect the bag until it is confined in a cavity, an insertion device that fits the closure in the bag and presses it with a tip until it is held and closed in the bag. The bag is then released and continues on the production belt. (Machine-translation by Google Translate, not legally binding)

    [0002] Automatic insertion machine for a new bag closing model.
    [0003]
    [0004] TECHNICAL SECTOR
    [0005]
    [0006] The invention is located within the technical sector of the procedures that industries use for the automatic closure of bags made of flexible materials and that can contain any product.
    [0007] The typology of machines to which I refer specifically must meet these characteristics:
    [0008] . They are integrated into an industrial production tape.
    [0009] . They carry out fully automatic mechanical actions necessary to insert the closure system in the bag.
    [0010] . They release the bag once the closure is in place and it can continue to move on the conveyor belt.
    [0011] . The machine is supplied with new closures from an external warehouse.
    [0012] . The conveyor belt must stop briefly for the closing actions to take place.
    [0013] . The machine is synchronized in its operation with the movement control of the production belt.
    [0014]
    [0015] STATE OF THE ART
    [0016]
    [0017] As it is a machine specifically designed to handle a new patented closure model with the application number 201730875 there should be no precedent for its existence in the industry as a material object or for the presence in any technical report of a machine similar to the one used. described in another section of this same document. The machines that are currently used in the production lines to close bags use other closing devices: laminated wires, adhesive tapes, clamps, heat sealing, etc.
    [0018] The design of this machine is fully adapted to the special mechanical characteristics and Fermat's spiral shape of the new closure.
    [0019]
    [0020] TECHNICAL PROBLEM RAISED
    [0021]
    [0022] The new closure model can be placed manually in the bags in a simple way and that guarantees the tightness of its interior, but it is not economically efficient or profitable to do so in high production industries.
    [0023] A new machine is needed that, integrated into the production chain, automatically and efficiently performs the task of inserting and closing the new closures for a wide typology of bags
    [0024] The proposed machine must meet these conditions:
    [0025]
    [0026] . A design that allows it to be easily integrated into existing production lines. . The design of its elements and its operation must be very simple to achieve a reliability that ensures a stable production flow.
    [0027] . The closure insertion procedure must consist of the minimum mechanical actions necessary to achieve the speed that the industry demands in the production chains. . Once the closure is placed in the bag, the inside of the bag must be sealed securely.
    [0028] . The system that supplies the seals to the feeder of the insertion machine will be external to it and adaptation of some model already in operation in the industrial market. The simplicity of the mechanisms must translate into a fairly low cost of the machine.
    [0029] . The machine could be adapted with minimal modifications to the insertion of the new closure in bags of any size or kind of flexible material and also adjust it to insert it anywhere in the bag. The operation of the machine would be similar in all these circumstances.
    [0030]
    [0031] EXPLANATION OF THE INVENTION
    [0032]
    [0033] The purpose of the machine is to automatically insert an open closure into a part of the bag (Figure 7) and then close it (Figure 8).
    [0034] The bag closures inserting machine can be integrated into an industrial production chain (Figure 1) (Figure 2) (3) that transports the bags (Figure 1) (2) with an open end (Figure 1) (1) to be closed with the new spiral closure (Figure 7).
    [0035]
    [0036] The bags must pass through an opening in the machine (Figure 1) (Figure 2) (4). When the end of the bag to be closed reaches the opening plane of the machine, the conveyor belt stops for the time necessary for the machine to carry out the entire procedure of automatic insertion of the closure.
    [0037] The actions are powered by an electric motor (Figure 1) (Figure 2) (6) controlled by an electronic microcontroller device (Figure 1) (Figure 2) (7).
    [0038] The machine can be considered to be made up of several systems, with specific functions and that act in coordination. As the machine's operating sequence is activated, the following systems can be distinguished:
    [0039]
    [0040] a) Supply line of the seals to the machine (Figure 9).
    [0041] b) Lock feeder to the insertion system (Figure 5) (Figure 6).
    [0042] c) Mechanism to tighten the bag (Figure 3) (Figure 4).
    [0043] d) Device for inserting and pressing the closure in the bag (Figure 3) (Figure 4).
    [0044] e) Actions to end the cycle (Figure 4).
    [0045]
    [0046] a) Pipe for supplying seals to the machine (Figure 9):
    [0047]
    [0048] Transport the new locks (Figure 7) to the machine's lock feeder.
    [0049] The prior technical procedures necessary to prepare the closure when it reaches that system make use of technologies that already exist in the industry for other purposes (for example, industrial vibration machines) and that can be easily adapted to the characteristics of this closure. .
    [0050]
    [0051] Those procedures are:
    [0052]
    [0053] . The closures are initially deposited in a bulk hopper. They are not hooked together because there is a very fine thread (which has been formed in the industrial phase of the closure molding) and which extends between the ends that make up the open part of the spiral closure (Figure 7) (6).
    [0054] . The closures must then be transferred to an already commercialized system (for example, industrial vibration machines), which manipulates them and places them in the correct position for the subsequent actions of the machine.
    [0055] . The closures accumulate in a conduit that has an interior profile (1) in which these closures (2) fit and that prevents them from moving, forming an ordered vertical pile of closures.
    [0056] . In this conduit there is a blade that cuts the provisional thread of the closures as they advance.
    [0057] . The closures are gravity propelled towards the closure feed mechanism.
    [0058]
    [0059] b) Lock feeder to the machine (Figure 5) (Figure 6):
    [0060]
    [0061] It receives the closures from the closure supply duct and places them in a receptacle that will move to the position where the bag closes.
    [0062] The closures form an ordered stack in the vertical conduit (1) that connects to the feeder.
    [0063] The feeder is made up of a disk-shaped part (5) that has another part (3) assembled on its surface in which the closure (2) from the supply duct (1) fits.
    [0064] Once a closure is deposited in that receptacle, the disc rotates 90 ° driven by an electric motor activated by a microcontroller.
    [0065] The receptacle deepens a little on the surface of the disc so that the seal can drop down and settle into the conduit. When the disc rotates, the curved surface of the disc at a high level with respect to the base of the closure receptacle, prevents the next closure of the conduit from descending to the feeder.
    [0066] As the disc that transports the closure rotates, the space between the closure and the outer casing of the feeder narrows, this displaces the base (4) on which the closure sits, which is movable and compresses a spring located below from the base, accumulating mechanical energy.
    [0067] When the disc has rotated 90 ° and is in front of an opening (6) in the casing that retained it, it is driven by the energy of the spring to the insert receptacle, which will then transfer it to the bag to be closed.
    [0068] Once the procedure of closing the bag has been completed, the disc rotates 90 ° in the opposite direction to the previous turn until it is located under the closure supply duct, this causes a new closure to descend by force of gravity to the disc receptacle from the feeder and start another machine cycle.
    [0069]
    [0070] c) Mechanism to tighten the bag (Figure 3) (Figure 4):
    [0071]
    [0072] It consists of two sheets (1) (5) that close symmetrically to each other, moving in opposite directions. The piece (5) fits into the gap formed by the two sheets that make up part (1). The shape of the pieces presents an axial symmetry necessary for the bag to be collected in a uniform way and for the pressure to be homogeneous throughout the involved surface of the bag during closure
    [0073] At the beginning of the closing procedure, the sheets (1) (5) are separated, leaving inside them a space (15) that will occupy the end to be closed of the bag, which has been transported by the production belt and will stop when it arrives. to that place .
    [0074] The electric motor (11) receives the command from the microcontroller (12) to activate, transmitting the thrust through the wheel (20) to the gear system (19) (17) (13) by means of a toothed belt (18) that moves the assembly and the wheels arranged in such a way that the blades (1) (5) of the machine move in opposite directions and in a symmetrical way.
    [0075] The toothed wheels (17) (13) mesh with the lower part of the blades (which are toothed) by a rack-and-pinion mechanism that moves the blades linearly in opposite directions. The sheets are held by lateral guides (14) (3).
    [0076] As the sheets (1) (5) move in opposite directions and narrow the gap (15) between them, the bag is collected in the area of contact with the sheets and by the angular shape of the inner edges of the sheets the surface of the bag is reduced until at the end of the movement of approach of the sheets (Figure 4) the part of the bag on which it is operated is rolled and is pushed by a slot in a sheet (Figure 3) (2) until it is confined to the bottom of a slit (9) where the spiral closure (10) is fitted.
    [0077]
    [0078] d) System of insertion of the closure in the bag (Figure 4):
    [0079]
    [0080] The part of the bag to be closed has reached in its path the receptacle of the closure (9), by the only opening that it has and which coincides with the open part of the spiral closure (Figure 7) (6), the bag continue to advance a little until it stays inside the closure in the optimal area to achieve maximum compression when closed.
    [0081] The sheet (5) that contains the cavity (9) that transports the closure (10) when making the approach movement towards the other sheet (1) has come into contact with a part that has the lower side in the form of an inclined plane ( 4) . This part is located in the fixed part of the machine structure (it does not move) and in such a position that when the insertion system (6) passes, with its upper side inclined, both inclined and pressure planes come into contact the insertion system (6) slides, which causes it to move towards the bottom of the machine following the path determined by some lateral guides (7), when moving a tip (8) is projected and in place with the maximum travel of the insertion system, it reaches the closure receptacle (9), enters it through an opening and reaches the spiral closure (10), affects a projection that it has on the surface (Figure 7) ( 5) and presses it until, due to the elasticity of the closure, the projection (Figure 7) (3) engages with the projection (Figure 7) (4), thus leaving the closing spiral closed, with the bag fastened inside.
    [0082]
    [0083] e) Actions to end the cycle (Figure 4):
    [0084]
    [0085] After closing the bag, the microcontroller (12) activates the motor (11) so that it rotates in the opposite direction and the blades (1) (5) separate. When the insertion system (6) departs from the inclined plane (4), the springs that it has at its base push back the tip that pressed the spiral closure, leaving the receptacle where it is located.
    [0086] The spiral closure (10) when it is in a closed situation has a smaller diameter than when it is open and therefore it can come off the cavity (9) that held it, with the bag inserted in it.
    [0087] When the opening (15) between the two sheets is maximum, the microcontroller activates the transport belt (Figure 1) (3) so that the already closed bag advances and another new bag is positioned for closing actions, beginning a new cycle of machine operation.

    [0100] PREFERRED EMBODIMENT OF THE INVENTION
    [0101] The explanation of the invention and the observation of the figures of the drawings present a preferred embodiment of the invention, sufficiently describing the elements that make up the machine and the mode of operation thereof.
    [0102] The automatic movement of the machine parts requires the action of a stepper electric motor directed by a microcontroller programmed with the necessary instructions to execute the mechanical actions that the machine requires.
    [0103] The basic design of the machine would not vary to be used with different types of bags, it is only necessary that the flexible part to close of these be placed between the two lateral sheets of the machine and that this area of the bag be compressed enough to that fits into the closure located in the cavity of a sheet of the machine.
    [0104] To adapt the machine to closures of different sizes or variations of its basic shape (Figure 7), the internal contour of the supply pipe of the closures (Figure 9) (1) would have to be modified to adjust it to the exact profile of the closure and to adapt the contour of the cavity where the closure would be located for its specific profile in the closure feeding and closure insertion systems in the bag.
    [0105] To adapt the machine to different designs of the projections of the closure (Figure 7) (5) in which the tip of the insertion system presses, the shape of the end with which it exerts pressure on the closure should be varied.
    [0106] To adapt the machine to closures made of different materials that have the property of resilience, the intensity with which you press the tip of the insertion system when closing the bags would have to be adjusted.
