Automatic reel of polyester straps for transporting goods.

Description

The present invention relates to an electronic and mechanical device for winding polyester straps for transporting goods and for extracting it from the machine, the strap of which remains kept wound by means of a manual device with metal pins.

Portable device allowing winding or rotation thanks to an electric motor or gearmotor by pressing an electronic push button, an ergonomic handle, a rechargeable battery, an electronic system to connect the battery to the gearmotor or motor depending on the state of technique.

The present invention relates to an electronic and mechanical device which, thanks to its innovative lug pulley, saves time thanks to the winding which is no longer done manually but electrically. The resolution of the resulting ecological problem is likewise very substantial thanks to the reduction in space that these straps took up by being rolled up by hand and being discarded most of the time in the trash cans, thus taking up a more than substantial place in them this. The recycling of these straps can therefore also be greatly facilitated than before.

The winder is intended for the retail sector, construction sites and everything related to the packaging of goods, to unpacking with these plastic straps (polyester) any sector and activities combined to send goods and storage. It is in this way intended for the professional and industrial environment.

The invention comprises an ergonomic handle, to which is attached a central system to which are attached four shells forming together a "cylinder" or protective shell opening by bursting, an innovative catchy pulley with lugs allowing the rapid attachment of the straps . Said catchy pulley with lugs is connected to a gearmotor itself connected to a li-po battery and to an electronic system. Said catchy pulley is provided with a manual engagement system of metal pins used to hold the wound strap after it has come out of the

-2machine. During the delivery of goods, the straps "strips" are cut to allow the unconditioning of the goods on the pallets. With the machine held in one hand, the end of the cut strap is inserted into the space provided for this purpose in the shell. By pressing an electronic push button the gear motor powered by the li-po battery drives the innovative catchy pulley with high speed as well as the strap being hung in one of the many hooking lugs. When it is wound inside the machine and kept wound by means of four pressure pistons, it is necessary to engage the metal pin in a U shape thanks to the locking system of pins incorporated in said innovative catchy pulley by pushing said pin with a pusher provided for this purpose and fold the longest part of said metal pin on the strap flat once it is engaged around the wrapped strap. The machine can be opened thanks to the four shells opening by bursting and thus being able to extract the wound strap and kept wound thanks to the metal pin.

Concerning the drawings and initially the figures from 1 to 19, a system for winding and extracting polyester straps in the preferred embodiment of the present invention comprises an ergonomic handle divided into two distinct parts: a straight part 2 in which there is a 7.4 volt li-po battery 26 connected to a gear motor 36 and an electronic push button 24 and a left-hand part 1 comprising an electronic push button 24 for the activation of the gear motor 36, an innovative pulley catchy to "Pins" 30, of a system with four pressure pistons 10 surrounding the pulley for holding the winding of the polyester strap 31 inside the machine, of an engagement system with metal pins in shape of U 29 specially designed for the compact maintenance of the polyester strap once wound up and out of the machine, of a cylindrical protective shell opening “bursting” into four distinct parts 6.7 , 8.9 for the extraction of the polyester strap, of a system for opening the four shells, of an electronic system supplying the geared motor.

The right part of the handle is provided with three holes 39 to allow the latter to be fixed to the body of the rewinder 3 where all the parts of the invention are grafted. Three fixing studs 45 are located inside this same part to accommodate the left part 1 of the handle. In the right part of the handle 2 is added a location to allow the placement of the battery 26 as well as an outlet hole 49 for the battery recharging cable 26.

The left part of the handle 1 is provided with three fixing studs 45 for fixing to the right part of the handle 2 using screws. This is provided with a hole receiving the electronic push button 24 and an opening 48 through which the power cables of the gearmotor 36 pass.

The two parts of the handle together form an "arch" (fig.l; 41) allowing the thumb to be placed there and therefore protecting it when the four shells open 6,7,8,9.

Once the polyester strap 31 is introduced into the machine, by pressing the electronic push button 24, the gear motor 36 being placed in the center of the machine rotate the catchy pulley 31 by winding the polyester strap 31 all around it.

The catching pulley 30 is provided with 360 ° hook lugs 50 allowing the polyester strap to be hooked almost instantaneously when the latter is introduced into the gap of the shell 8 of the machine.

BE2019 / 0023

-6The hanging pulley 30 is provided with a locking mechanism with pins 29 in its center specially designed for the compact maintenance of the polyester strap 31 once it has been removed from the machine.

A loader 17 provided with several “notched” locations for receiving metal pins in the shape of a “U” 29 with one side longer to fold down, are positioned with the longer side facing forward. The charger is placed in the center of the catching pulley and, like a stapler charger, this is pushed as and when a metal pin 29 is used thanks to a pressure spring placed (fig.5 ; 13 for the location of the spring) between the magazine pusher 18 and its stop piece 20. When a metal pin 29 abuts inside the catching pulley and the polyester strap is wrapped around said catchy pulley, the pin can be engaged around the strap by means of a pusher 15 provided with a tongue 40 making it possible to engage a metal pin around the polyester strap. The pusher 15 slides in a guide rail 14 to be able to engage a metal pin.

Once the metal pin 29 engaged around the polyester strap 31 the longest part can be folded down on the flat of the polyester strap (fig. 7, 32).

The polyester strap 31 does not unwind and is kept rolled up inside the machine thanks to four pressure pistons 10 in the shape of an "L" ending in a small wheel 11 at its end placed parallel to the strap and being disposed distributed around the catchy pulley.

The constant pressure of the pistons as the strap is wound up is provided by four extension springs 12 for each pressure piston. Each pressure piston 10 slides in a guide (fig. 8; 4) to ensure its vertical sliding.

To recover the polyester strap 31 once it has been wound up inside the machine, it opens in four separate shells (fig. 1; 6,7,8,9). Each shell is made up of three branches, each with their own specific features. In fig.12 the shell 7 as well as the other three have a branch with a female lug 37 hooking for closing the hull to a male lug (fig. 13; 22).

A second branch 46 serving only as a guide and sliding in a square tube (fig. 11; 5) allows the stability of each shell when it is opened and closed. The square tubing 5 forms for the insertion of all the guide branches 46 of the shells, a cross characterized by a round opening in its center for passing the geared motor 36 there.

BE2019 / 0023

-7A third branch 47 is used to "propel" the shell for its opening thanks to a pressure spring located between two guides closed at their end (fig. 10; 43)

This third branch 47 is provided with an opening at its end 42 allowing it to receive a stop block 33 sliding between two guides 19, thus ensuring even better stability and a stop distance for each shell during the opening.

We can also see an opening at the top of the shells 7 and 8 (fig. 2) allowing the passage of the pusher 15 as well as the passage of the thumb in order to be able to fold down the longest side of a metal pin 29 on the flat of the strap polyester 31.

The four shells open thanks to an opening system with male and female lugs as explained above and a reel spring system (fig. 13; 33) allowing the male lug disc 22 to return to its original place during triggering of the four shells by pressing the trigger 25. A stop block 26 has been provided to allow the male lug disc 22 to stop precisely opposite the first branch with female lug 37 of each shell and thus allow its opening and closing with each lowering of all hulls.

The winding spring 33 keeps a constant winding tension thanks to a fixed disc (fig.14,18,19; 23) to which the winding spring 33 is hooked inside the male lug disc 22. Said fixed disc is itself attached to the cross piece of square tube (5) by the end of the face of the small cylinder that composes it.

In fig.15 we can see the position of the opening mechanism in the open position before it thanks to the winding spring 33 returns to its original place.

The central part of the machine 3 is the part where all the parts of the machine are grafted. It is the major part because it provides the link between all the parts of the invention.

It is also characterized by 3 face holes 44 enabling the right handle 2 to be screwed in and held.

The machine also has a cylindrical shell 21 allowing the rear protection of the gear motor 36 and provided with an opening for the passage of the power cables of the gear motor 36.

The invention has been explained according to its preferred embodiment (s) as described above. However, it should be noted that many other possible variations or modifications can be made without altering the scope of the
