Abstract

The supplier has an opening for bags and other bundles. A machine has a coil store of bags, which is detached by a mechanical system of a roller tractor, a left superior roller and a right superior roller with assistance of a motor roller. A radial opening system opens the bag or the bundle. The radial opening system has a superior suction cup, an inferior suction cup, a nozzle and a centrifuge pump, which is driven by a control unit.

Description

Supplier with opening for bags and others wrappers

Object of the invention

The present invention relates to a machine whose function is the supply and opening of bags, bags, gloves and other types of packaging that bear similarity to these, (from now on when we say "bag or bags" we we will also be referring to bags, gloves and other types of wrappers) Thanks to this system the user will not need separate some bags from others or open them, so that the machine He will take care of doing so, saving considerable time. its Main application can be: at the end of the boxes in supermarkets and other types of shops where use is necessary of bags, gas stations, self-services, packaging areas, etc.

Background of the invention

Since time immemorial the bags, sacks, gloves and other types of wrappers, usually plastic, are used as an article container or as a protection element. Its greatest use stands out in supermarkets, fruit shops self-service, gas stations, etc. Handling separately and Opening of each bag is done manually and requires a excessive time, which is transferred in an economic loss of the company where this activity is being carried out, in the case of a supermarket, for example, the loss is multiplied by the factor of people waiting in a cash queue, All this caused by a slow opening of the bags. further there is another economic loss derived from the lack of control of units and their misuse. The space occupied by loose and messy bags is excessive.

The invention that we recommend in this patent, fully and satisfactorily solve all the problem, mentioned above. The user receives the bag, glove or other type of packaging which supplies the machine, separated and open, from unit to unit, in a very short time in such a way that while the user is filling a bag, the machine Supply the next one and open it. It is also an advantage the reduced space it occupies with respect to loose bags.

Description of the invention

The supplier with opening for bags and other wrappers, it is constituted by a machine which will remove and open a bag or other type of packaging as the feeder is charged and adjusted. He device has a space acting as a reservoir with object of containing the bags, well stacked in zigzag or rolled up forming a cylinder to reel or coil mode, from there the bags are removed. Advancing the position of a bag, it is inflated with air being open and accessible to the user, so that when we exert a slightly weak extraction force, the bag is will detach and start another cycle like the previous one until leaving another Bag accessible to the user. You can incorporate a device that notify when you reach the reservation, for replenishment and an accountant with the number of services performed.

Brief description of the drawings

To complement the description of this invention and in order to help a better understanding of same, according to an example of practical realization of invention is accompanied as an integral part of said description, a set of drawings, illustrative and not limiting, is It presents the following:

Figure 1.- Represents in a way schematic, the pneumatic circuit which performs the operation of opening of bags or other wrappers.

Figure 2.- It is a drawing of the device that It is recommended in this patent, in side elevation view with the open lid for a better representation of the performance of the invention. Mechanical, electrical and pneumatic devices.

Figure 3.- Represents a front view of elevation, of the mentioned device, dividing it from another perspective with respect to the previous figure.

Preferred Embodiment of the Invention

The supplier with opening for bags and other wrappers, may be preferably made of the following form:

A housing (20) that will serve as a container for most of the devices and the bags and a lid (19) that it will contain the remaining devices, by opening us will allow access to the loading and replacement of the bags (1). He system incorporates an open cover sensor (23) which will send a signal to the control unit (27) in the event that the cover (19) was open and in this way, as security, would prevent operation of all systems.

The control unit (27) will have the purpose of activate, monitor and process the operation of the systems Electrical and electronic

A mechanical system consisting of: a roller tractor (9) that is turned by the roller motor (24) which will drag the bag (1) that comes from the coil (21) and collaborating as conductors-presses the roller upper left (7a) and upper right roller (7b) to position the bag (1) at the appropriate point for the opening phase whose point is read by the position sensor (3). The function of opening is done by the pneumatic circuit, mainly composed by a centrifugal pump (11) whose function will be to extract the upper suction cup air (2) to hold one side of the bag (1), of the lower suction cup (18) to hold the other side of the bag (1) and the lung chamber (13) producing a contraction  of the membrane (14) and consequently a shot of the connecting rod (14) and in turn an angular movement in the rocker arm (17) that will be transformed into a displacement of the lower suction cup (18), The opening of the bag being initiated (1). When emptiness is done, the air inlet valve (28) will automatically open and the centrifugal pump (11), through the blow duct (10) by middle of the nozzle (4), will blow air into the bag (1), completing the opening of it. The blade motor (26) will activate the blade (6) by separating the bag (1) and remaining user layout If the bag (1) is removed, the shot sensor (5) send a signal to the control unit (27), producing another cycle, as we have detailed above.

Claims (2)

1. Supplier with opening for bags and other wrappers, characterized mainly by the opening of bags (1) or other types of wrappers that can be sucked and inflated by means of a pump, preferably a centrifugal pump (11), sucking air from a top suction cup (2) and another lower suction cup (18) will start the opening of the bag (1), facilitating the entry of the air that will blow the nozzle (4), completing the total opening. 2. Supplier with opening for bags and other wrappers, according to claim 1, characterized by a lung (13) capable of contracting the membrane (14) exerting a force in the same direction on the connecting rod (16) and transmitting it to the rocker arm ( 17) to produce a displacement of the lower suction cup (18) to produce the separation of the two faces of the bag (1) for opening opening.
