Description

The invention relates to a transport container for textiles Packs, in particular of sliver, the transport vessel a rectangular base and a vertical one has displaceable base element. Such a transport container is known from EP-A-0 344 484.

It is common to see the spinning positions for example To supply OE spinning machines with sliver which is placed in spinning cans with a round cross-section. Such round cans are usually made of plastic and point to the gentle storage of the sliver on the Spread out a spring-loaded can bottom. The Round cans are filled by a transport vehicle from the Line or card picked up to the spinning stations of the OE spinning machine transported and there against empty ones Spinning cans exchanged. Because the diameter of such round cans is larger than the width of the spinning positions at which the Sliver is processed, it is necessary in the field of These spinning cans spin at least in two rows to be placed one behind the other.

Because empty spinning cans against spinning cans as soon as possible will be exchanged with new template material, after the "Wild change" system worked. The can changing process turns out, especially when automatically changed and the jug to be changed in the back row is arranged, quite complicated.

Attempts have therefore already been made in the past been using this can changing process to simplify flattened spinning cans.

In DE-GM 88 12 622 and DE 40 15 938 A and DE 40 18 088 A is the use of such flattened Spinning cans in the transport network stretch / OE spinning machine described.

These are known, for example, from DE 25 17 344 A. Spinning cans are the same width as the spinning station concerned spinning machine so that all with Original material loaded spinning cans next to each other be positioned and thereby a second, rear Row of sliver cans can be avoided. The use of flattened, spinning station-wide spinning cans has one Simplification of the can changing process in the area of Spinning stations led; however, it has been shown that such Spinning cans have certain disadvantages. So could for example the handling of these transport facilities in the Do not satisfy the area of the route or card.

There are further, for example, by DE-AS 11 07 566, the DE-AS 15 10 248, DE-OS 19 23 621 or DE-GM 76 18 538 Transport containers known to be a non-circular respectively have a rectangular base. These shipping containers partly consist of many individual parts and are in theirs Manufacturing quite expensive.

The invention is based on the aforementioned state of the Technology based the task of creating an inexpensive spinning can create that is suitable for transport automation and good is to be handled.

According to the invention, this object is achieved by a transport vessel solved according to claim 1.

The use of two interconnected, identical wall parts, which extend over the entire length of the Extend wall offers the advantage, among other things, that such components are inexpensive to manufacture. Besides, is creating vertical guides for the floor element quite simple, because only on the outside of the wall parts appropriate recesses must be provided.

In a preferred embodiment it is provided between the Switch on wall parts upper and lower spacers so that a guide gap is formed between these spacers. The Spacers are either unsolvable, for example through a Adhesive connection, or detachable via bolts with the Wall parts connected.

In a development of the invention, at least one of the a sliver receiving device in the two upper spacers in which the sliver end after the filling process of the transport container on the route and inserted if necessary can be secured.

Furthermore, at least one of the bottom two points Spacers an intervention possibility for a manipulator or the like, so that the transport vessel during the Can filling process, transport or changing the can is easy to handle at all times.

In an advantageous embodiment of the invention, the base element a lattice-like structure with an outer frame and intermediate struts. Such a structure is stable and light. Also on the frame of the floor element molded lateral pins that the bottom element in the Guide gaps in the transport vessel wall. The cones are round in the area of the leadership columns and end in an essentially angular molded part. Such Training has the advantage, for example, that on the one hand it is possible to pivot the floor element about its longitudinal axis and emptying sliver residues downwards; on the other hand can the bottom element on the molded parts by a suitable Device, for example by the pressure fork of the Linear unit of the route, securely fixed and defined be lowered.

The production of the Transport vessel according to the invention when the wall parts a thermoplastic. Such thermoplastics are known to be very resistant, resulting in a high Life of the transport containers leads. Also are Thermoplastics very suitable for series production.

A suitable manufacturing process is, for example so-called injection molding process. By appropriately molded Ribs and ridges are made using this procedure manufactured wall parts relatively light and yet extremely stable. It is also very beneficial on the wall parts all necessary guide sections at the same time, To include support edges and the like. So are for example in the area of the upper and lower edge of the Wall parts facing outwards and on the longitudinal guides Lower edge additionally an inward-facing contact edge arranged for the floor element.

In an alternative embodiment, the Foam wall parts made of polyurethane. With this procedure arises between two hard, relatively thin wall layers and a soft core layer. Even those using these procedures manufactured wall parts are characterized by low weight, high rigidity and long service life.

To the transport containers or their contents at any time identify and thus draw conclusions for example on the It is also possible to pull the place of manufacture of the sliver provided to attach data carriers to the transport containers. It can be either coded or codable Trade disks.

1 schematically shows a transport vessel according to the invention 8 during its loading or filling on a route shown.

Line 1 has, as usual, a turntable (Keuler) 2 for the loop-like placement of sliver 9. Before the Line 1 is a linear unit 3 is arranged, the Recording platform 4 oscillating in via a drive 5 Direction R and L can be moved. Is on the recording platform 4 also a guide unit 7 with vertically displaceable Pressure forks arranged. These pressure forks 6 summarize how shown during the filling process of the transport vessel 8 under the pin 24 of the bottom member 23 and put through defined lowering of the bottom element 23 a gentle Sliver storage in the transport container 8 safely.

Fig. 2 shows the transport vessel 8, which is preferably an in has a substantially rectangular base, also in perspective view. Two identical wall parts 10 are about spacers 11 to 14 and bolts 16 so put together that between the wall parts 10 guide column 15 with a width B arise in which with pin 24 of Bottom element 23 is guided.

Those manufactured, for example, by injection molding Wall parts 10 are made of a thermoplastic. Here are, as indicated in FIGS. 2 and 6, for stiffening the relatively large wall sections of beads 20 and ribs 21 molded. Furthermore, in the area of the upper edge 17 or the lower edge 18 longitudinal guides 19 are provided. In the area of the lower edge 18 there is also an inside directed support edge 22 arranged for the bottom element 23.

As indicated in Fig. 7, the longitudinal guides can also be designed so that they are arranged side by side Interlock the transport containers.

It is of course also possible to remove the wall parts 10 Foam polyurethane. In this case, between two relatively hard outer layers a relatively soft Core layer. After curing you get a light, but very stable construction, so that after this Manufacturing process manufactured wall parts on additional Bumps and ribs can be dispensed with.

As can be seen in particular from FIGS. 2 and 4, the Base element 23 has a grid-like structure. A frame 29 is braced with struts 30, so that a light but stable component is created. Lateral pins are on the frame 29 24 arranged, which are arranged between the wall parts 10 Pass through guide column 15. These pins 24 have, as in Fig. 4, a round section 27 and a itself adjoining essentially angular molded part 28. The round section 27 is in the guide gaps 15 guided and enables pivoting of the bottom element 23rd about its longitudinal axis, so that, for example, thread tape remnants after can be emptied below. The molded part 28 serves on the one hand as a connection element for the on route 1 or the linear unit 3 arranged pressure forks 6, so that Bottom element 23 is guided securely during the filling process, on the other hand, the molded part 28 locks the bottom element 23 while rotating about the longitudinal axis in the guide columns 15.

As shown in FIG. 3, at least one of the upper spacers 11 and 12 a Sliver receiving device 26, for example in the form of a Notch in which the sliver end after completing the Filling process stored and defined for the subsequent Processing process can be kept ready.

Furthermore, at least one of the lower spacers 13 and 14 a device 25 for the intervention a manipulator or the like arranged so that the Transport vessel 8 at any time, be it during the filling process the route, during the transport from the route to OE spinning machine or during can change on the OE spinning machine can be handled optimally.

By coded or encodable data carrier 31, for example is arranged on one of the two wall parts 10 is one Identification of the transport vessel 8 or the Transport container contents possible. Such coding enables an independent assignment of the transport container through an automatic transport and handling device.

The transport vessel 8 according to the invention adjusts overall inexpensive to manufacture transport vessel that both in Range of lines (cards) as well as in the range of OE spinning machines is easy to handle and therefore optimal suitable for transport automation.
