Definitions
- the present invention relates to a method and a device for transferring containers of shredded tobacco.
- Cubic or frustum-shaped containers preferably made of wood or metallic material, are conventionally used to store shredded tobacco.
- Such containers generally but not necessarily contain approximately 100-200 kilograms of tobacco which may also be slightly compacted.
- the containers are currently stored in appropriately provided spaces and, in order to maximize storage density, they can be arranged in stacks of two or three containers, according to their dimensions.
- the containers must then be conveyed to a feeder into which the tobacco is to be unloaded; the feeder takes care of the dosage and transfer of the tobacco in a downstream direction at a plurality of cigarette-making machines.
- the feeders are usually arranged side by side and aligned in a number which is sufficient to cover the requirements of the factory.
- means which grip the containers one by one and sequentially in order to then tip them into the feeders according to the demand of product by the downstream system.
- This solution then requires to perform a new stacking operation to return the stack of empty containers to a system for removing the stack.
- EP-A-0375631 discloses a device for transferring containers of shredded tobacco to individual feeders (hoppers) of cigarette making machines, comprising containers arranged on movable supports in the form of motor driven carriages.
- the aim of the present invention is to solve the above-mentioned problems, eliminating the drawbacks of the cited prior art, by providing a device for transferring stacked containers of shredded tobacco to individual feeders of cigarette-making machines which allows to provide faster processing of the stacked containers by being able to control a plurality of feeders for this purpose according to specific requirements.
- an important object of the present invention is to provide a device which allows to reduce time and cost for transferring the stacked containers.
- Another important object of the present invention is to provide a device which can be introduced effectively in the tobacco processing cycle, allowing to optimize processing spaces and times.
- Another object of the present invention is to provide a device which is reliable and safe in use and can be manufactured and obtained with conventional machines and equipment.
- a device for transferring stacked containers of shredded tobacco to individual feeders of cigarette-making machines characterized in that it comprises a station which moves at right angles to the feeder, which is provided with means for gripping, tipping, stacking and unstacking the containers arranged on supports which can move parallel to the feeder and at right angles thereto.
- the method for transferring stacked containers of shredded tobacco is defined by claim 12.
- the reference numeral 1a designates a container which is full of shredded tobacco, designated by the reference numeral 2, and the reference numeral 1b designates a container which is similar to the preceding one but is empty.
- the reference numeral 3 designates a single feeder which is adapted to convey the shredded tobacco that can be stored therein to subsequent treatments.
- the reference numeral 4 instead generally designates a device for feeding an empty stacked containers 1b and containers 1a full of shredded tobacco to individual feeders 3 which are adapted to convey the product for example to cigarette-making machines (in the figures only one feeder is shown).
- the device is constituted by a station 5 which is movable along adapted guides 6a and 6b which are arranged transversely to a loading hopper 7 of a plurality of feeders 3 preferably arranged side by side.
- the station 5 also has adapted conventional means for sliding coupling on the guides 6a and 6b and comprises two vertical posts 8a and 8b between which at least one cross-member 9 is provided which is movable vertically by virtue of adapted lifting means 10, such as hydraulic and/or pneumatic jacks and/or gearmotors which actuate for example adapted chains 11 which are appropriately guided and connected to said cross-member.
- adapted lifting means 10 such as hydraulic and/or pneumatic jacks and/or gearmotors which actuate for example adapted chains 11 which are appropriately guided and connected to said cross-member.
- Means for gripping and tipping a full container 1a or an empty container 1b are also associated at the cross-member.
- Such means are preferably constituted by two arms 12a and 12b which are slidingly associated transversely to the cross-member 9 and clamp in a vise-like manner the lateral surfaces of a container.
- the two arms can also rotate because of the presence of adapted means which are keyed for example on the cross-member or are adapted to provide a rotary motion to said two arms.
- the lifting means 10 allow, together with the means for gripping and tipping the containers, to stack and unstack said containers as specified hereafter.
- the containers 1a and 1b which are mutually stacked beforehand, are arranged at movable supports 13a and 13b which are constituted by a pair of roller beds which are arranged side by side and are mounted on wheels 14 which can roll at adapted rails 15 which are arranged approximately parallel to the guides 6a and 6b.
- the rails 15 are also arranged to the side of a plurality of additional fixed roller beds 16 which are orientated in the same manner and have the same width as the movable supports 13a and 13b; the rollers of said supports are motorized, so as to allow to send and/or receive the full containers 1a and the empty containers 1b at the station 5, which is thus interposed between said fixed roller beds 16 and the guides 6a and 6b.
- the containers 1a and 1b can thus move both parallel and at right angles to the guides 6a and 6b and to the feeders 3.
- the method entails performing the following operating sequence, as also shown by the figures: first of all, a stack 1a of full containers is placed at the movable support 13a, which conveys said stack at the chosen feeder 3.
- a centralized logic unit which accordingly comprises a program which, by means of adapted sensors and/or controls, determines the operating sequences of the various components of the device and the movable supports.
- the rollers After positioning the movable supports in front of the chosen feeder 3, the rollers are made to move so as to convey the stack of full containers 1a onto the facing fixed roller bed 16.
- the station 5 is positioned in the interspace between the stack of full containers 1a and the feeder 3.
- the lifting means 10 position the arms 12a and 12b adjacent to the lateral surfaces of the full container 1a that is arranged at the top of the stack, which is gripped and tipped so as to unload the shredded tobacco 2 into the hopper 7 of the feeder 3.
- the station 5 tips the empty container 1b backwards, moving on the guides 6a and 6b, so as to unload the empty container 1b at the adjacent movable support 13b.
- the feeder 3 does not require further amounts of tobacco for a certain time, it is possible to order the station 5 to move at a further feeder, in front of which another stack of full containers 1a has been stored in the meantime.
- the mobility of the station therefore allows, in consideration of an adapted control system, for example of the computerized type, to be present in order to feed shredded tobacco to a chosen feeder, unstacking the full containers 1a, unloading them and stacking the empty containers 1b laterally to the preceding ones.
- an adapted control system for example of the computerized type
- the stack can be conveyed by means of fixed roller beds 16 at the movable support 13b, which can in turn be moved for disposal and storage.
- the invention has achieved the intended aim and objects, a device having been provided which allows to transfer stacked containers of shredded tobacco to individual feeders of cigarette-making machines, increasing the treatment speed of the stacked containers since it can serve a plurality of feeders in a short time according to specific requirements.
