DE2359393A1 - Goods batch binding system - uses guide tube to place wire round side and top of batch - Google Patents

Abstract

The system is particularly for tying bales of cellulose material, one or more wires being wrapped round the bale. Each wire is inserted above or below the bale from one side through a tube, and emerges at the other side. The tube, together with the portion of wire still inside, is then moved sideways to the top or bottom of the bale, and thrust, again complete with the wire inside it, through to the other side of the bale. A number of tubes can be provided so as to place several wires in position at the same time, and the length of each tube can be at least equal to the bale width. Rollers can be provided in the tube ends for guidance of the wire.

Method and device for binding units of goods.

The invention relates to a method for binding units of goods, one or more wires being placed around the unit of goods and tied together on one side. The method is intended to be used for all goods units of the type where: It is advisable to tie the goods unit together to achieve a pack that is held together as well as possible. Mention should be made here of goods units, such as pallet loads, where the unit is tied to the pallet, large cardboard boxes that are to be tied around, etc. as well as goods in bale form, especially those types that are to be tied together under pressure, in order to be as good as possible to give compressed pack. Examples of such goods "packed in bales" are wood pulp _f cellulose, hay and straw

to be mentioned, under wire is also band-shaped below Understand material such as steel strip. The invention also relates to a device for carrying out the method .

When tying ¹ ton, for example, cellulose pulp balls with iron wire, while they are being pressed in a baling press, the "usual method is to pull the ends of cut wires through grooves in the upper and lower pressing plates and, after manually stretching the wires, to connect their ends, while, When the press is opened, the bales expand to the extent that the wire loops allow it, whereby the wires at the corners of the bales are strongly bent and otherwise aligned will vary in length and shape from the manual tightening performed, and there will be bends in the wires and similar fortuitous factors.

Also known is a method for tying mass bars, one cut to the appropriate length straight wire is bent in two places at right angles, so that, on the whole, one is U-shaped Bracket with two parallel legs and a central part, the length of which corresponds to the height of the ball of mass when compressed State corresponds, is formed, whereupon this bracket is shifted horizontally in its entirety, so that its legs are inserted simultaneously above and below the bale in the press while the bale is being pressed is held compressed until the central portion reaches one side of the bale, whereupon that on the opposite side Side of the bale protruding ends of the legs are tied together so that the bale is not can expand significantly when the press is opened. A more regular form of the Bale, however, the method is cumbersome considering that each lanyard is desired in advance

509823/0111

Must be cut to length and bent into a U shape then at the same time in both the upper and the lower pressing surface to be introduced. .

The present invention has for its object to avoid the disadvantages of the known methods and a method to create, which simplifies the UmbihduhgsvOrgang and in a simple way: can be carried out purely mechanically. .

According to the invention, this object is achieved by means of a Method solved, which is characterized by -.,. what made the process claims emerge, -. ".- -:

The invention also relates to a means of implementation of the procedure, which is characterized by what emerges from the facility claims.

.Even if the invention in connection with binding has been developed from balls of mass, it has become inclined that they are also beneficial for tying others around Units of goods, e.g. pallet loads, large boxes, etc., can be used. With such units of goods ■ Passing the wire under the unit can be difficult if this stands on a belt or the like or has to be guided into the space between the legs of a pallet. at Pallet loading - for example, the technique has been used that the Binding tape is laid out and the pallet itself back and forth is moved here: in order to obtain the correct positioning between the pallet and the band for the binding, which is a significant greater work than the method according to the invention entails. The invention therefore also offers great advantages: this Area of use.

A simple binding is achieved in this way; technology that is so flexible at the same time that; they the Adjusted conditions at the individual points and using simple, familiar control and management methods are automated can be. The knowledge on which the invention is based is that the binding wire or the binding band is so flexible that it can be bent around the edge of the tube or some other reversing device and thus in principle only requires a guide to move around the

509823/01

Unit of goods around to be able to be brought into place correctly. In this way you avoid the somewhat cumbersome and Space-consuming work process that consists of making a bracket by bending it before tying it together.

The invention is explained in more detail below using an exemplary embodiment that is shown in the drawing which shows as follows:

Fig. 1 is a side elevation, the very schematically the mode of operation of the device according to the invention with baling press, shows and

Pig. 2 the facility in Pig. 1 seen from above, with the upper press plate and the mass ball removed.

The drawing shows a mass bale 1 which is pressed together between the pressing plates 2, 3 of a baling press is. Grooves 4, 5 are formed in the press plates 2, 3 with a size such that a tube 6 is inserted into the grooves can be. A binding wire or binding band 7 is passed through the tube 6 and comes from a schematically shown supply 8.

A ball of mass is usually tied with several wires, and in the example shown there are three wires and consequently three grooves 4, 5 in the press plates, three tubes 6 and three supplies 8 have also been used. For the sake of clarity reference is made below only to a wire and associated devices.

In carrying out the procedure, one can now proceed in different ways, depending on the local conditions and what material is to be packed in bales.

The method can be carried out as follows: The pipe 6 is placed as shown in the drawing. The wire 7 is advanced from the supply 8, as shown, through the tube 6 and into through the groove 4 in one Press plate 2 and on the other side, where it is gripped by the retaining device 10. The wire can then of a device not shown, which is between the supplies

509823/0111

and the pipe 6 is provided. The tube is then shifted up to the other pressing plate 3 in parallel with the aid of known means, as indicated by the arrow B, until it reaches a position ^! the line 9 occupies along. As a result, the wire is bent around the end of the tube 6 and guided along the end face of the bale to the upper press plate. The tube 6 with the wire 7 is then inserted into the groove 5 in the press plate 3 by means of known means (not shown), as indicated by the arrow C. The wire is thereby bent around the edge of the tube and pulled out of this as the tube is pushed into the Uut 5 and wrapped around the bale. When the tube has been fully inserted into the press plate, the end of the wire will be gripped by the gripping device 11 which brings the end of the wire together with the end held by the device 10, and the wire can be tied together. The device 10, in the process of doing this, may have pulled a little on its end of the wire so that a piece of sufficient length is obtained to be tied together. ·

. This procedure can also be carried out in the manner be that the wire is not cut between the supply 8 and tube 6, but is passed through, as above mentioned, while at the same time it is pulled on by the supply 8 .. The supply 8 can also be used together with up the pipe 6 to the line 9. In this The wire is then pailed after passing through the Press plate 3, i.e. in the area of the device 11, severed. After the connection, you already have a wire introduced into the groove 5 so that there is a possibility to reverse the process, i.e. on the press plate 3 instead of starting at press plate 2. But you can too Pull out the tube 6 with the wire 7 again and start at the press plate 2. .- ■ '■ -. '

Another way to carry out the procedure, is that the tube 6 together with the Wire is inserted through the rage 4 in the press plate 2,

50 9 8 23/0111

if necessary, that the wire is pushed into the tube after it has been inserted «This may be necessary if the Bale material has a tendency to be pressed down into the hat 4, so that the retraction of the wire is difficult. The Robr 6 is then out of the groove 4 pulled out so that it has carried out the movement indicated by the double arrow A, and so that it is in turn is in the position shown in the drawing. The tube 6 is then slid parallel to the line 9, as described above, so that the wire around the end of the tube is bent and wraps around the end face of the bale, whereupon the tube is pushed into the groove 5, after which a Tying is carried out after a separation of the thread in the area of the device 11 ..

Here you have two options, namely to pull out the tube with the wire so that the Tube at the line 9 has carried out the movement indicated by the double arrow C, whereupon the tube to initiate a new binding to the press plate 2 down parallel shifted or you can insert a new bale which is compressed in the press before the pipe is pulled out so that a reverse of the process is achieved.

As mentioned above, there are many possible variations when carrying out the method. The wire 7 can E.g. from the supply 8. to the extent that it is placed around the bale, but on the other hand it can also if held by the plague holder 10, are automatically advanced when the pipe is displaced. Furthermore, instead of bending the wire around the end of the tube 6, scroll wheels or the like may be used for convenience the bending of the wire can be provided, which can be particularly useful in the groove 5, where the wire is doubled is laid, i.e. that the wire is on the outside of the Pipe is laid along while it is guided into the pipe at the same time.

For holding the end of the wire and for tying it together can a wide variety of devices be used?

509823/0111

the. The wire end coming out through the groove 4 can, for example, be made so long that it can easily be bent over along the bale and held in place, or the device 10 can have fixed means and at the same time can be designed so that can pull out a sufficient portion of ■ '. wire and high drove it to the bale along. the Torrichtung 11 may also, if necessary, grip the wire or purely down, turn it to the apparatus 10. the Zusammenbinduhg the wire ends may be in a any suitable manner. take place.

- Even -when referring to the invention the special and most complicated case when tying in has been described in a press, it is clear that the same device can also be used for other types of goods, such as large Cardboard boxes and pallet loads can be used, making the Appearance of the facility will not be significantly changed. With the starting point in Fig. 1 and 2 of the drawing can one thinks here that the press plate 2 is replaced by a pad or a pallet and that the press plate 3 is omitted. One becomes thereby, a "binding a unit of goods; 1 in exactly the same way as described above, by simply moving the pipes. Finally, it should also be noted here, that the pipes are not necessarily / closed. Pipes too need to be, but can also be channel-shaped pipes.
