Definitions
- the present invention relates to a simple, reliable and universal device, that is to say that it can be used for any product as soon as the bags can be opened by a rotary cutting means. .
- One of the aims of the invention is to ensure automatic and continuous operation by a device, machine of reduced size, preferably closed, while arriving at a higher rate while the work is less demanding. In fact, better and safer working conditions are obtained, which allows the device to treat harmful and dangerous products without entraining the usual residual dust.
- the device can process all types of old and new bags made of paper, plastic, jute, etc ...; it can process bags filled with very diverse materials such as powdered products, grains, granules, fibers, compacted or not, etc. It is however, due to the high safety of the work it brings, intended more specifically to the treatment of harmful, smelly, toxic products, etc ... In addition, the device by its cutting system and wide opening of the bag, it will be perfectly emptied.
- bag opener devices comprising cutting facilities where the bags must be opened beforehand, generally right through along a horizontal or vertical line.
- the product In certain types of known devices, the product must be separated from the fragments originating from the cutting of the bags by a sieving operation. This results in a significant dust problem and despite everything there are generally small fragments of the bag in the product.
- the present invention overcomes these drawbacks by providing a device which is characterized in that it essentially consists of a modular box or not and placed on a chassis, a bag movement system, generally an endless conveyor belt, which can be equipped laterally with a rim or lip in order to avoid overflowing of the products, a bag cutting system comprising one or more rotary cutting means normally allowing the opening on the three sides of the bags, generally on the front and laterally .
- the cutting means are mounted on pivoting arms or on an additional chassis and they are brought towards the center by springs or even air, oil pistons, etc.
- the device comprises a system of removal of empty bags, consisting on the one hand of oscillating guide elements and on the other hand of a set of cylinders preferably having the shape of small wheels. All systems operate electrically or pneumatically. The device is finally provided with a means of evacuating the product leaving the cut bags.
- a walled box (la, lb, lc, ld), mounted on a frame (2) itself placed on feet (3); by (4) an endless conveyor belt rotating on rollers (5): by (6), Figures 1 and 2, and (6 '), Figures 3 and 4, a cutting installation comprising rotary means (7) of cutting, either Figures 1 and 2, mounted on pivoting arms (8), or, Figures 3 and 4, arms with translatory movement (8 '), acting like each other under the action of springs or pistons air or oil (not shown); by (9) oscillating guide elements and by (10) wheel-shaped cylinders, these elements (9) and the set of cylinders (10) forming the system for removing empty bags.
- (11) there is shown the empty bags evacuation zone; by (12) a funnel provided for the outlet of the products contained in the bags.
- the evacuation zone (11) of the bags comprises an archimedean screw (13), while on the other hand, according to the embodiment of Figures 3 and 4, has provided a discharge funnel (14).
- the rotary cutting means (7) execute an oscillating movement around two axes of rotation according to the arrows (15) and (16), whereas in FIGS. 3 and 4, they execute a rectilinear movement of va - back and forth according to arrows (17) and (18).
- the device is also completed by an electrical or pneumatic drive system (not shown). It is also provided (not shown) that the device is equipped with an electrical cabinet which provides automaticity, security, as well as the necessary interlocks.
- the device can also be supplemented with anti-dust equipment, a filter, etc.
- the product transporter can be completed by a crusher, a shredder, an archimedes screw; transport can be mechanical or pneumatic; Similarly, the transport of the cut bags can be completed with an archimedes screw, a press, a crusher, etc.
- the bags being introduced linearly and at a regular rate thanks to a fixed and wide entry airlock, are thus maintained until they are opened by the cutting system (7) including the rotary cutting means ( 7) are located, upstream, before the bags pass, in a directional alignment along the longitudinal axis of the device.
- the rotary cutting means (7) cut the bags (20), one of which is shown diagrammatically by (19) in the different figures 1 to 4, the bags moving in the direction of advance of the conveyor belt (5), according to the arrows (21).
- each bag successively exerts pressure against the first cutting means, then the second.
- the detection system causes, in an oscillating movement, according to the arrow (22), the upward movement of the guide elements (9), so that the bags are stripped (bags cut and empty) is detached and separated from the product which it contained, and taken over the product by the cylinders (10) which entrain the bags under the bags towards the part (11), while the product which they contained falls into the funnel ( 12).
- An automatic shutdown system (not shown) is provided for cases where the bags are not being fed satisfactorily or when the cutting is poorly executed; the immediate stop having the advantage of stopping the further introduction of the bags, which would risk in the otherwise, damaging the various elements of the device in the event of a malfunction.
