DESCRIPTION

Multiple distributor of flexible tarpaulins in packaging device in open rigid packages. Technology Sector

The present invention relates as indicated in the statement of the present specification to a mechanism complementary to the existing mechanical devices for introducing canvases in rigid containers with superior opening.

The sector of the technique to which this utility model refers is that corresponding to the devices oriented towards the food sector in charge of the packaging of previously made and closed Iona bags or other type of flexible or semi-flexible closed blister type container, etc. ., whose contents are products in rigid receptacles with superior opening, although its application in other industrial sectors with a similar technical affinity for the introduction of all types of flexible or semi-flexible closed supports whose contents are loose sphere-shaped articles is not ruled out, ellipsoid, ovoid, paraboloid, cubic, cylindrical, etc., including liquid, granulated or crushed products in a wide variety of types and sizes of rigid containers provided they maintain a superior opening

State of the art

In the stores of food products, fresh foods are processed for consumption under optimal conditions. For this there are mechanisms for washing, brushing, polishing, drying and calibration. The last process before its distribution is the packaging of the same in flexible or semi-flexible containers type bag or blister and its subsequent storage in rigid industrial supports that facilitate its manipulation.

There are productive processes that introduce fresh products in flexible textile supports of different sizes and weights, with or without handles, etc., and once closed, they are deposited by manual means in rigid industrial supports that facilitate their manipulation.

But various mechanical devices or means are also known to carry out the packaging process in a basic way of the product inside the bags and in some of them, its placement inside rigid containers.

For this there are many devices and mechanisms that perform this operation automatically or semi-automatically. We are not going to study the process of packing these mechanisms, since it is not the object of this useful object. But there is a circumstance that characterizes all of them and it is that everyone receives the bags in a single column and introduces them into the packages by ordering them in two or more columns.

The production time of said devices is reduced because the processing times of said bags slows down when waiting for the arrival of the bags one by one. In the present invention we present a bag dispenser complementary to the packaging mechanisms that is able to receive the bags in multiple columns and process them all simultaneously.

The invention patent No. 2301338 and its addition No. 2537640 reflect a complete mechanism for packaging bags in open containers. Both, together with all its precedents consist of devices with a single bag entry.

This utility model corrects and complements the previous mechanical models in which the reception and entry of the bags into the mechanism refers, increasing the performance and productivity of said mechanisms to the maximum.

We will see these inventions and others in detail below.

US Patent 2061490 (1936) of Albert R. Thompson, consisting of a mechanism consisting of a roller conveyor that moves the market and dumps it over rigid receptacles with upper opening. Said containers move through a conveyor, and when they reach their filling station, they rise to the height of the merchandise carrier. As main drawbacks, it should be noted that the bags receive a strong blow in their broth to the rigid container, since the mechanical device does not accompany said descent. Neither the bags are ordered inside said container, nor the market is compacted, which means that the market is stored by making a mound in its center and leaves the perimeter of the rigid receptacle empty, wasting its volume and making it difficult to stack. On the other hand, the mechanism stops the process of receiving new bags during the process of replacing the rigid container filled with another new vacuum, which delays the rate of work.

US2608038 from Hoaguesprague Corp. (1952) protects a very complex packaging system where it receives the packages vertically, forms a ton by supporting them in the air by means of a prey hand. Then lift the container until the market is housed inside. It is an excessively complicated and appalling mechanism. On the other hand, its large dimensions make it unattractive for the market. In addition, it receives the market in a single column.

US Patent 4353198 (1982) belonging to Koppe Robert in which a pre-formed bag filling mechanism is defined consisting of a closed circuit conveyor where the bags arrive from their feeding point to a hopper carousel that fills them while they rotate. Finished the process and closed the bag, it is deposited on a conveyor for eviction. Said invention does not solve the introduction of the bags into rigid deposits.

U 273944 (1983) belonging to Padulles and Peralta, s.a., describes a scrollable hopper under a weigher, and in its mouth a conventional bag filler. Once the bag is closed, it is thrown on a conveyor, but no mechanical means are established for its introduction into rigid containers.

Patent EP0248463 (1987) of Prakken Bouwe consisting of the pouring of vertical bags into a rigid tank with upper opening. For this, there is a bag conveyor, which is falling neatly to an accumulation zone; Once the column is finished, it is tilted 90 ° and by means of a hopper and a pusher, it is moved to the interior of the rigid receptacle. This invention is designed to work bags with a more or less rectangular shape, since if the bag has an amorphous shape, it would be inoperative. In addition, by not accompanying the load during its descent into the interior, it will be unavoidable bumps and scratches, which is an impediment to its use in food products. It also has a single product entry to the device.

US Patent 4660352 (1987) DE Package Machinery Co (US) consisting of a conveyor that moves the column packages towards a second transverse conveyor until the combination of both causes a package layer to be configured. On the other hand, a rigid deposit conveyor takes these to the filling area. For the filling of the rigid container, the packages will be deposited on sheet metal blades which, when turned, will deposit the merchandise inside said deposit. The main drawback is that the broth of the packages to the interior of the rigid receptacle involves blows to them, which does not make it applicable to the agri-food industry. On the other hand it does not compact the market inside the container to take advantage of the maximum space. The combination of the movement of the blades to deposit the goods into the rigid container means that the bags will be piled up in the center of the rigid receptacle while the sides of the container will remain empty. This effect will impair the stacking of rigid containers and significantly reduce the process performance. Describe, like the previous ones, a single product input channel.

US0225037 (1987) of Wilson Foods Corp. where a mechanism for packing meat in trays is described where a column feeder deposits the trays on a taco conveyor. Perpendicular to it are located several conveyors that transfer the meat fillets and lead them inside the tray. It does not make clear how it introduces the fillets inside the trays in an orderly manner.

Patent DE3635099 (1988) of Affeld Verpackunngsmach (DE), consisting of an ingenuity that contains a conventional conveyor belt on which the ready-made bags circulate, and dumps them over a rigid receptacle with top opening. The dump is unitary, so the cadence is very low and it is necessary to stop the reception of bags during the change of rigid packaging. The aspect of not hitting or rubbing the market is also neglected. On the other hand, the bags are dropped on the rigid packaging, without compacting the merchandise, and therefore, leaving useless empty spaces, since the contents of the bags, when it touches the bottom of the rigid container, spreads and prevents that the new bags can take their place. The bags enter a single column.

EP0256598 by Prakken Bouwe solves the packaging of packages inside rigid containers quite elegantly. For this, it has a retractable belt conveyor that dispenses the packages and deposits them on a tray. Parallel to said package conveyor, at a lower level but to the side instead of below, empty packages run. When a column of packages is generated, a pusher sends the column into a mobile bowl. Said bowl has movement and is capable of making two or more columns. At the bottom of said bowl, there are shovels that open and drop the entire column inside the container. This invention has several drawbacks: the packaging conveyor is parallel to that of packaging, but is not below, but next to it, so much space is lost and compact mechanisms cannot be generated; on the other hand, an invention is sought that does not drag the market, since it is fragile products that deteriorate by friction and finally, drop the column from very high, which means that the market will lose order when it falls to the bottom of the container Although the market entry apparently takes place from two independent conveyors, both converge in a single mobile bowl that moves to one side or the other alternately, being unable to process or deposit several columns of product simultaneously inside the containers.

P US5029431 (1990) belonging to Weening Frederick which describes a mechanism for filling receptacles with bags or bags of food products consisting of a conveyor of ascending shovels on which the bags are deposited and this goes

unloading inside open rigid receptacles on its upper face. Said rigid tank circulates through a transverse conveyor to the named one, and when it is full, it is removed so that it enters a vacuum. In said invention, the bags are dropped without any order, hitting the products inside by the strong broth inside the rigid container, so it is not indicated for fresh foods, which deteriorate easily. On the other hand, by not ordering or compacting the flexible containers, the space inside the rigid container is poorly utilized, accumulating the market in the center and leaving the perimeter of the rigid container empty. In addition, while changing the containers, the blade conveyor must be paralyzed and therefore the reception of material, lowering the rate of the same.

P 2049160 (1991) belonging to LINPAC Plastics Espana, s.a. consisting of a mechanism for filling and closing bags of food products using a vertical hopper and a fruit dispenser. When the bag is finished, it is deposited on a conveyor for eviction. Said ingenuity does not introduce the bag onto any rigidly received receptacle.

P 2060479 (1991) belonging to Fdo Machinery Espanola, s.a. It consists of a bag-filling weigher that dumps the product on hoppers, weighs them and when it reaches its optimum weight, it moves the market transversely to a bag-filling area. It does not indicate anything about the subsequent manipulation of flexible receptacles in rigid containers with top opening.

US 5123231 (1992) by Richard J. Fallas and David M. Fallas. It shows a package packaging device that has a line of conveyors that, by speed changes, group the packages to form the tonings. Then, by means of a retractable conveyor they deposit the tongada on some shovels that when they open introduce the market inside the rigid containers. The main problem of the invention is its large dimensions. On the other hand, they only work on one column, and the invention of this writing must work with two or more columns of packages in the same container.

P 2066710 (1993) belonging to MAF s.a., describes a hopper to which bags already made through a conventional conveyor arrive. Under said hopper there is a bag distributor whose outlet nozzle has movement in the three Cartesian axes. Said invention suffers from two main drawbacks given its combination. The most important is the high degree of friction and number of blows that the bags suffer from the exit of the conveyor upon arrival at the hopper, its circulation through a rigid articulated tunnel and its broth inside the rigid receptacle with upper opening. Another major drawback is its low production rate, since it deposits the bags one at a time through said dispenser, having to stop feeding the next bag until the previous one is deposited in its place. It is also necessary to stop receiving the bags while changing the rigid deposit. Another drawback that does not solve the invention is that it drops the bags inside the rigid receptacle, without compacting, so that the market inside the bag, when touching the bottom of the rigid container, spreads through it preventing new bags from being able to take its place leaving free gaps inside the receptacle and therefore not optimizing the available space.

P 2104493 (1994) belonging to Matlas Vilar Canos, which describes a device for filling rigid containers with flexible gender bags. Said mechanism has a superior feeding of rigid containers that dose in unit form until its place of filling. Under it is a bag carrier that doses in column from 1 to

rigid deposit, which is inclined to facilitate filling. Once the process is finished, the container is finished. Said invention has the disadvantage that the broth of the bag to the rigid container will cause the content of it to hit. On the other hand, the distribution of the bags inside to achieve an adequate combination in the maximum use of space is not contemplated. The reception of bags will also be paralyzed while changing the empty container to a full one, reducing the cadence of the device. You get the bags one at a time.

U 1031104 (1995) belonging to IMETEC, S.A.L., describes a hopper in a conveyor that receives the bags in a single column already made and by means of shovels drag them to make two columns. After it, a second conveyor moves the two columns to the position of the rigid deposit and throws them inside. Said invention has several drawbacks such as the fact that by dragging the bags over the band and throwing them into the container, the market is deteriorating by bumps and scratches. It will also be necessary to stop the delivery of bags while changing the rigid container filled with another vacuum, lowering the productivity of the mechanism. It does not compact or distribute the bags inside the containers, so that it will be misused and the bags poorly stored. On the other hand, the dimensions of the device are enormous, which makes it uninteresting for potential users who lack space for their location.

P 2148040 (1997) of EMPAC, s.a. that describes a procedure and mechanism to make a global management of bagging the product and without releasing the bags, transport these to a filling station of containers to finally deposit these inside a rigid tank with superior opening. The main drawback is that it is unable to handle bags that are already made from any mechanism. On the other hand, the broth of the bag inside the container is abrupt, hitting in this process the market that carries inside. Nor does the market inside the rigid receptacle compact to take advantage of the maximum space, so the bags will be poorly stored and with many empty spaces.

P 9701583 and its Certificate of Addition 2187329 (2000) both of GIRO GH, SA, which describes a global device for bagging and filling rigid receptacles with said bags consisting of an air bag circuit that circulates from the filling stations to the filling of containers. Being a global device, it does not contemplate the introduction of ready-made bags and from other mechanisms, which makes it useless for a user who already has a bag filling device and wants to handle ready-made bags. As in other previous inventions it is neglected that the introduction of the bags into the rigid containers occurs without friction or bumps. The bags inside the rigid receptacle are also not compacted to take advantage of the maximum space while losing productivity by having to stop feeding bags made of weft fabric while replacing the filled rigid tank with another vacuum.

P 2301338 (2006) and its addition n ° 2537640 of Automated Research and Development, eliminates some of the drawbacks mentioned above and describes a compact mechanism for inserting bags with product in containers. It consists of a longitudinal conveyor to the mechanism located in the lower part of the same container transport. It also has a bag delivery conveyor that receives them in a single column and then a set of retractable conveyors that deposit the goods on longitudinal shovels without them suffering friction. The container is raised to receive the bags when the blades are opened and descends again to the conveyor. This invention would be the basis of

Application of the utility model object of this document, which describes a set of bag processing conveyors that feed through different simultaneous, but controlled lanes, the product.

Explanation of the invention

The previous mechanisms oriented to the packaging of bags inside rigid containers with superior opening receive the bags in a single column and introduce them inside the package in an orderly manner in several columns, where each of the columns will have a certain number of bags. Depending on the size of the bags and the packaging that is intended to be packaged. Said number of bags may vary, there being a very high number of packaging combinations.

With the previous inventions, upon receiving a single column of bags, the device leads them to a column or another as necessary.

We will not describe how such ordering and product introduction occurs, since this process is perfectly explained and protected in previous inventions. Yes, it is important to explain that the introduction of the product columns into the containers is done simultaneously, with the intention of optimizing the volumetric occupation of the package by the product.

With the present invention it is intended to receive several columns of bags simultaneously, with the intention that each input column of the product feeds the corresponding column that will finally be introduced into the package.

But it may happen that one column is already complete with all its bags and ready to be introduced into the container, but another parallel column is devoid of bags. Then, it will be necessary to divert that flow of incoming bags from the saturated column to the column that lacks them in order to be able to complete them and introduce them simultaneously in the container.

The present invention describes a delivery conveyor capable of receiving two or more columns simultaneously and processing them so that the product is arranged in several columns.

The bag delivery conveyor (s), commanded by actuators, will be fed by means of multi-rail feed conveyors that will have an independent drive, in order to control the flow of market entry.

Said flexible bags must already be made and closed, they can be of any format, with or without handles, with or without a label band, closed manually or automatically and from any manufacturer.

Said delivery conveyor may be rotatable horizontally so that it has a rotation axis and distributes the bags to different columns as necessary. Said rotation will be controlled by a complementary actuator that could be linear or polar.

An alternative is that said conveyor is fixed and has one or more blades that push the bags to each of the suitable rails in which the column must be formed. These blades will be commanded by linear or polar actuators that will adequately control the movement of the bags.

But you can also use one or more translatable or retractable transverse conveyors on themselves so that they deposit the bags in each of the columns and can change the column on which to deposit the bags and thus be able to change the product flow as appropriate . This method can be applied when the number of columns is 2 or more.

In any case, with all these alternatives it will be perfectly explained how the distribution conveyor of the bags in columns will be constituted.

On these feed conveyors a set of optical or mechanical detectors should be installed that will count the bags to change direction when the columns are constituted or so that the distribution blades change in the gap between two bags and not deteriorate the market.

For this reason it is necessary that the bags arrive well aligned and separated to make a correct count, because otherwise the detector can count a single bag when two joints go together.
