Abstract

To form a multipack consisting of a large bag made of foil material in which more than six bags filled with crisps or other material are packed a certain number of bags arranged in order is transported to a filling/shaping/sealing machine where a relatively large bag is formed from foil around said bags. The filled bags are fed in rows located one after the other, each row containing at least two bags, to the feed end of a conveyor provided with carriers, each row of bags being guided in the space between two successive carriers, the distance between the carriers essentially corresponding to the thickness of the bags. The rows of bags, standing on a short edge, are moved with the aid of the conveyer provided with carriers (15) into a position opposite a pusher element that pushes the rows of bags out of the gap between the carriers onto an essentially horizontal conveyor belt provided with side guides, which conveyor belt feeds the group of bags positioned alongside one another and one after the other into the filling/shaping/sealing machine.

Description

Title: Method and installation for forming a multipack consisting of a large bag made of foil material in which more than six bags filled with crisps or other material are packed
In the first instance the invention relates to a method for forming a multipack consisting of a large bag made of foil material in which more than six bags filled with crisps or other material are packed, a certain number of bags arranged in order being transported to a filling/shaping/sealing machine where a relatively large bag is formed from foil around said bags.
It has been found that with known methods the multipack cannot be formed to fit tightly around more than six filled bags.
The aim of the invention is to avoid this disadvantage and to carry out the said method in such a way that the multipack formed around the more than six bags is pulled tightly over the well-arranged bags.
According to the invention the method is to this end characterised in that the filled bags are fed in rows located one after the other, each row containing at least two bags, to the feed end of a conveyor provided with carriers, each row of bags being guided in the space between two successive carriers, the distance between the carriers essentially corresponding to the thickness of the bags, in that said conveyor moves said rows of bags standing on edge into a position opposite a pusher element, which pusher element pushes the rows of bags out of the gap between the carriers onto an essentially horizontal conveyor belt provided with side guides, which conveyor belt feeds the group of bags positioned alongside one another and one after the other into the filling/shaping/sealing machine which fits a tight-fitting bag made of foil around the bags.
The invention furthermore relates to an installation suitable for feeding filled bags to a shaping/filling/sealing machine in which a certain number of filled bags can be packed in a multipack, comprising: an essentially horizontal conveyor provided with carriers and means for bringing a certain number of filled bags between the carriers.
Known installations of this type are used to pack a limited number (for example up to a maximum of six) filled bags in a multipack. The bags, lying in stacks between the carriers, are fed to the shaping/filling/sealing machine in order to be packed in a multipack. If the number of bags per multipack is too high (more than 6), it is found that the multibag cannot be stretched tightly around the stacks of bags because bags lying on top of one another slide off one another. This makes the filled multipack unattractive to the consumer. The same disadvantage is found in the case of vertical feed of filled bags into a shaping/filling/sealing machine: the filled bags are too loose in the multipack. The bags cannot be kept under control if more than six bags have been grouped lying on one another in stacks.
The aim is to construct the abovementioned installation in such a way that the disadvantage is avoided. To this end the installation is characterised in that means are positioned at the input end of the conveyor provided with carriers, which means are able to place rows of bags, fed horizontally, row by row into the space between two successive carriers in such a way that the bags are on edge in the top part of the conveyor provided with carriers, and in that a pusher element is positioned some distance away from the feed point for the rows of bags, between the carriers, which pusher element is able to push the rows of bags contained between the carriers off said conveyor provided with carriers essentially perpendicularly to the direction of transport of the conveyor provided with earners.
A conveyor belt adjoining the side of the conveyor provided with carriers is arranged directly opposite the pusher device, which conveyor belt has side guides in order to guide the rows of bags standing on edge, which have been pushed off the conveyor provided with carriers by the pusher device, in that position to the shaping/filling/sealing machine.
Preferably, the conveyor provided with carriers is of the smart track type and the conveyor comprises at least two conveyors, each consisting of at least one endless flexible conveyor element, such as a chain, wherein each conveyor has a separate drive as well as means for switching the drives on and off and controlling the speed of transport of the conveyor elements and wherein at least one section provided with carriers is fixed to each of the conveyors by means of fixing elements, wherein the means for detachably mounting a section provided with carriers on a fixing element of a conveyor are constructed such that the distance from said means to two flexible conveyor elements located alongside one another a small distance apart is essentially the same.
The fixing elements can have a projecting part, such as a pin, that can be inserted through an opening made in a section provided with carriers in order to fit such a section.
The fixing elements preferably consist of L-shaped sections and the conveyor preferably has two parallel pairs of flexible elements. A free edge extends from the two side edges of the sections provided with carriers, on either side of the carriers, which free edge extends into a U-shaped guide section rigidly mounted on the frame of the conveyor.
The invention will now be explained in more detail with reference to the figures, which show an illustrative embodiment.
Figure 1 shows a cross-section through the conveyor of the smart track type according to the invention.
Figure 2 shows a plan view of this conveyor.
Figure 3 shows a longitudinal section.
Figure 4 shows a plan view of two chains located alongside one another, each chain belonging to a different chain conveyor.
Figure 5 shows, diagrammatically, a plan view of an installation for feeding more than six filled bags to a filling/shaping/sealing machine.
Figure 6 shows a diagrammatic side view of part of the installation according to Figure 5.
The conveyor shown has four endless chains which form two chain conveyors la, lb and 2a, 2b. The chain la of the one conveyor is a small distance away from the chain 2a of the other conveyor and the chain lb of the one conveyor is a small distance away from the chain 2b of the other conveyor. Instead of chains it is also possible to use other flexible elements. The distance between the chains la and lb of the one conveyor is greater than the distance between the chains 2a and 2b of the other conveyor. The chain la runs around a sprocket 4 driven by a motor 3 and a sprocket 5 that is not driven. The chain lb runs around a sprocket 6 driven by the motor 3 and a sprocket 7 that is not driven. The chain 2a runs around a sprocket 8 that is not driven and a sprocket 10 driven by the motor 9 and the chain 2b runs around a sprocket 11 that is not driven and a sprocket 12 driven by the motor 9. Means (for example computer-controlled) which are not shown and which are able automatically to switch the said conveyors on and off and to control the speed of the conveyors are installed on both motors 3 and 9.
The shafts of the sprockets 8 and 11 are mounted in bearings such that they run free on the common driven shaft 13 of the sprockets 4 and 6, whilst the shafts of the sprockets 5 and 7 are mounted in bearings such that they run free on the common driven shaft 14 of the sprockets 10 and 12.
A section provided with carriers 15 is detachably fixed to each of the chain conveyors 1 a, lb and 2a, 2b. In Figures 1 and 3 the section fixed to the conveyor la, lb is indicated by 16 and the section fixed to the conveyor 2a, 2b is indicated by 17.
The sections 16 and 17 have a projecting edge 18 on either side of the carriers 15, which projecting edge 18 extends into a horizontal U-section 19 that serves as a guide. There are thus two U-sections. L-shaped fixing elements 20 are attached to certain links of the chains. A pin 21 is fitted on the flange of these fixing elements that faces away from the chain concerned. The fixing elements 20 of the chains la and lb are mounted on the insides of the chains and the flange of these fixing elements that is provided with a pin projects inwards. The fixing elements 20 of the chains 2a, 2b are mounted on the outside of these chains and the flange of the fixing elements concerned that is provided with a pin 21 projects outwards. The sizing of the L-shaped fixing elements 20 relative to the distance between the chain sections, located alongside one another, of the chains 1 a and 2a and of the chains lb and 2b is so chosen that the pins 21 extend in the mid plane between the said chains la, 2a and lb, 2b.
Holes, through which the pins 21 can be inserted, are made in the projecting side edges 18 of the sections 16 and 17 provided with carriers. The distance between the holes in the side edges of the section 16 is equal to that between the holes in the side edges of section 17. Moreover, this distance corresponds to the distance between a pair of pins 21 of the L- shaped fixing elements 20 of the chains la and lb and to the distance between a pair of pins 21 of the L-shaped fixing elements 20 of the chains 2a and 2b. That is to say, although the distance between the chains 2a and 2b is less than the distance between the chains 1 a and lb, the distances between the holes, located opposite one another, in the side edges 18 of the sections 16 and 17 are equal to one another. The sections 16 and 17 fit both on the conveyor la, lb and on the conveyor 2a, 2b.
Close to one of the pairs of sprockets, the U-shaped guides 19 have a portion 19a (Figure 3) that can be used to replace the sections 16, 17 by sections having a different number of carriers and/or having a different distance between the carriers.
The pins 21 can, for example, consist of parts that are resilient with respect to one another. Incidentally, it is not precluded that pins 21 are arranged on the projecting portions 18 of the sections and the holes through which they have to be inserted are made in the L-shaped fixing elements 20.
The chains la, lb and 2a, 2b can easily be provided with any sections, provided with carriers, that are held in stock. These sections are then identical to one another.
The way in which the machine described above can be used can be seen in the diagrammatic plan view according to Figure 5 and the side view according to Figure 6.
Figure 5 shows two hoppers 23 and 24 for vertically feeding bags, for example in the case of hopper 23 the bags are filled with plain crisps and in the case of hopper 24 the bags are filled with paprika-flavoured crisps.
Two conveyor units 25, 26 and 27, 28 respectively are located below the hoppers and carry the bags fed via the hoppers over an essentially equal distance. By means of a robot, which is not indicated, the bags are placed in rows of three on a conveyor belt 29 and transported in the direction of the arrow to a slide 30 which deposits the row of bags successively in the spaces between the carriers 15, which are moved in steps, of section 16 of the conveyor la, lb. In the interim, section 17 on the chain conveyor 2a, 2b has arrived at accelerated speed in the position which is shown in Figures 5 and 6 and in which the spaces between the carriers 15 are opposite the pusher elements 31 of a pusher device 32 operated by a hydraulic or pneumatic cylinder or driven by an electric motor. By operating this cylinder the rows of bags are pushed onto the conveyor 33 and guided by side guides in the direction of the vertical arrow to the shaping/filling/sealing machine, which is known per se and is not shown, where the pack of bags is tightly and neatly enveloped by foil, which is shaped to give a sealed bag. In this way more than six bags can be packed in such a way that the result is a neatly filled, tight-fitting bag.
Various variants and additions are conceivable within the scope of the main claims.
