DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an automatic bag-dispensing device aimed at equipping the cash desk of a store, such as a supermarket.
2. Description of the Prior Art
When passing at the cash desk, the buyer deposits his purchases onto a conveying belt, the cashier takes them one by one to enter the price of same, then deposits them onto a second conveying belt for the buyer to be able to pack them in bags.
The bags, generally made of a film of plastic material, have the drawback of being difficult to be open; it is necessary to crumple them to separate the two sides of same.
To try to cope with this drawback, devices have been proposed in which the bags are hanging in batches from hooks above a shelf and are joined to each other by an easily sectile weld seam, so that removing the outermost bag results into the opening of the next bag.
These devices have however drawbacks, e.g. it often occurs that some bags do not separate from the next ones or that they do not open.
In addition, for some of these devices, the presence of hanging hooks, which are necessarily long in order to allow the hanging of a batch of a large number of bags, is an obstacle for the filling of the bags.
SUMMARY OF THE INVENTION
This invention is aimed at overcoming these drawbacks by proposing an automatic bag-dispensing device allowing the dispensing, one by one, of open bags.
The device according to the invention includes, a recess for bags flatly arranged in a stack two rotary means with parallel spindles placed close to each other, coated with a non-slip material, rotating in opposite direction to each other at different linear speeds at the periphery, at least one of which is capable of entering into contact with one of both outermost bags of the stack, in the vicinity of the bottom of the bag, with a view to carrying same between said rotary means.
According to an additional feature of the device according to the invention, at least one of the rotary means includes a central portion not driven in rotation, in front of which acts a means for gripping the median portion of the bag.
According to another additional feature of the device according to the invention, the rotary means are placed in a casing including, in front of the contact area of the means, an opening allowing the passing through of a bag and ending in a receptacle.
In a first embodiment of the device according to the invention, the rotary means are two rollers transversely positioned, side by side, above the bags, nearly in contact with each other, rotating in opposite direction, ascending along the center, and positioned in front of the lower portion of the bags; and it includes, on the other hand, means allowing, through a vertical translation, to bring the rollers into contact with the bag located on top of the stack.
In a second embodiment of the device according to the invention, the rotary means are two belts each passing on a pair of spindles on which they move in contact with each other, the two spindles closest to the stack of bags being transversely arranged, side by side, above this latter.
In a third embodiment of the device according to the invention, the rotary means are two belts mounted on rollers, a portion of one of which being able to enter into contact with the lower bag of the stack, with a view to carrying same between the two belts.
According to the invention, the bags may be slightly longitudinally offset with respect to each other, so that all the bottoms of the bags of the stack can be seen from above, in order to avoid the welded portions from overlapping each other.
Still according to the invention, the device may include several receptacles positioned side by side, the rotary means then being mobile transversely and capable of successively moving in front of each of said receptacles to deposit a bag into same.
The advantages and the features of this invention will clearly appear from the description which follows and which makes reference to the attached drawing, which shows a non-exhau
