Description

The invention relates to a transport arrangement or a transport system for parts with a transport box or container for receiving the parts.

In the production of parts, these must be transported in the material flow on the one hand from one processing station to the next processing station. The transport takes place for example via conveyors, alternatively, the parts are stored in boxes to bring them to the next station. Further, parts are also stored in boxes to wash the parts, so wash liquid residues, such as oil or the like, from the parts.

There are already known transport boxes or containers, which are used for the transport of products that need to be cleaned in box washing machines. Products are machined, similar components or parts, such as those resulting from manufacturing steps with machining. The components that are removed, for example, a turning, grinding, honing machine must still be cleaned of chips, dust and organic contaminants such as lubricants. As a container are mainly rectangular boxes made of perforated plate in use, so that the washing liquid passes from all sides to the products

During the washing process, the components in the container clash or slippage regularly, whereby the component quality, in particular the surface quality and dimensional accuracy of the components is impaired.

The publication DE 382 4275 , which forms a technical background, discloses a plant for cleaning, in particular for de-oiling, washing, rinsing and drying of industrial mass parts contained in a transport box.

The invention has for its object to provide a transport arrangement for parts, which allows a particularly gentle treatment and fixation of the parts in the transport box, regardless of the degree of filling of the transport box with parts.

This object is achieved by a transport arrangement with the features of claim 1. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims, the following description and the accompanying drawings.

The invention relates to a transport arrangement for parts, in particular for industrial mass parts. The parts are preferably identical or identically dimensioned parts. Particularly preferred are metal parts. In particular, the parts are designed as bearing parts, gear parts, etc. The parts preferably carry chemical residues from a previous processing step. In particular, the parts are contaminated, especially oiled. Optionally, the parts form part of the transport arrangement.

The transport arrangement has a transport box for receiving the parts. The transport box particularly preferably has a rectangular, optionally square, base area. Preferably, the transport box is formed longer in the longitudinal direction than in the transverse direction. The base is formed by a bottom of the transport box. The transport box also has four walls, in particular side walls, which are connected to one another in the direction of rotation, form corner regions and are fixed to the floor. Preferably, the corner regions each have an included angle of 90 degrees.

The transport arrangement has a clamping lid, wherein the clamping lid can be arranged at different heights in the transport box. In particular, the clamping lid can be arranged parallel to the ground in the different heights. Preferably, the base of the clamping lid is less than or equal to the base of the bottom and / or the transport box and / or an intermediate plane of the transport box. The clamping lid, for example, in an altitude range of more than 10 cm in the transport box can be arranged freely.

The clamping lid has a clamping device, so that the clamping lid can be clamped in the different heights in the transport box, so that the clamping lid is arranged so as to be non-displaceable with respect to the height. Preferably, the height can be selected in the transport box stepless or stepped. Such a cover allows a distortion of the components in the transport box, so that they are fixed in their bearings. Surface defects due to slipping or hitting the components can thus be prevented. The clamping lid can be clamped in different positions, so that different filling levels of the transport box are possible and different geometries of parts can be transported therein. For this purpose, however, the parts must of course be arranged within the receiving volume of the transport box. The clamping lid is easy to insert, remove and suitable for washing machines.

It is therefore an advantage of the invention that the clamping lid can be arranged at any height within the transport box, so that the parts can be secured in the transport box with the clamping cover so that they can not fall around uncontrollably. In this way, damage to the parts during transport or other processing operations can be prevented. In particular, the parts in the transport arrangement can be transported, manipulated and / or edited without risk of impact. Through the clamping lid, the parts are locked in a form-fitting manner in the transport box. It is possible to position the clamping lid depending on different degrees of filling of the transport box and the respective part geometry.

The clamping lid is reusable and can be introduced into undercut geometries of the transport box interior, while at the same time any tolerances or damage to the containers can be compensated. In particular, spherical components up to a diameter of 3 mm to 10 mm can be safely covered and fixed.

In particular, the clamping cover is partially formed from a perforated plate. This allows good access of washing liquid to the parts.

In a preferred embodiment of the invention, the transport box is designed as a wash box and has a multiplicity of passage openings in the walls and / or in the floor. It is optionally possible that the bottom and / or the walls are at least partially or even completely formed from a perforated plate or perforated sheet metal sections. Preferably, at least an area fraction of 50%, preferably at least 60% and in particular at least 80% is open, so that a washing liquid can be easily passed through the walls and / or the floor to wash the parts. Alternatively or additionally, the clamping lid is designed as a Spannwaschdeckel and has a plurality of through holes. The Spannwaschdeckel may in particular have a perforated plate or at least a perforated plate section. Preferably, the perforated plate section occupies at least 50%, in particular at least 60% and in particular at least 80% of the base area of the Spannwaschdeckels. In this realization of the invention, it is emphasized that the transport arrangement is intended for de-oiling, washing, rinsing and / or drying of the parts.

In a preferred constructional realization of the invention, the clamping cover has a first and a second cover section, wherein the clamping device presses apart the first and the second cover section in a clamping direction and thereby clamps the clamping cover in the transport box. Thus, the clamping lid is also formed variable in length or adjustable in length by the clamping device in the clamping direction. It can be provided that the change in length is formed so large that the clamping cover can be inserted into the transport box, even if the transport box has an undercut contour in the region of the input opening of the transport box, ie in the entrance area. Preferably, the change in length of the clamping cover of the untensioned state in the tensioned state of the clamping cover is at least 10 mm. In this embodiment, it is possible for mounting that the clamping cover can be tilted about the clamping direction initially to be inserted into the transport box and is subsequently aligned parallel to the ground. In this way, the clamping lid is very easy to install even with undercut contours. Optionally, the transport box in the entrance area on a gripping portion, so that the transport box can be accessed automatically. The gripping portion is formed for example by a cranking or taper of the upper edge regions of the walls. Preferably, the longitudinal extension of the clamping cover in the clamping direction in the untensioned state of the clamping cover is smaller than the free passage of the transport box in the clamping direction.

In a preferred embodiment of the invention, the clamping device has an actuating portion and a clamping portion, wherein the actuating portion and the clamping portion for clamping the clamping cover in the transport box cooperate. The operating portion is connected to the first lid portion and the clamping portion is non-slidably connected to the second lid portion. When clamping the clamping device of the actuating portion and the clamping portion are moved in the clamping direction relative to each other, so that the first and the second lid portion are pressed apart. The first lid portion is preferably formed as a first rectangular portion, the second lid portion preferably as a second rectangular portion, each of the lid portions having two corner portions of the clamping lid. Characterized in that the first and the second lid portion are pressed apart, the corner regions of the clamping cover are clamped or pressed into the corner regions of the transport box.

In a preferred embodiment of the invention, the actuating portion has a clamping lever for manual clamping of the clamping cover. The clamping lever is pivotable in or on the Operating portion arranged, wherein a clamping movement and / or pivoting movement of the clamping lever is parallel to the clamping lid. This embodiment has the advantage that the clamping lever does not or only slightly builds in height, so that the space requirement is low. Preferably, the actuating portion is formed with the clamping lever so that the pivoting range is smaller than the available range, which is defined by the transport box and / or the base of the clamping cover.

In one possible implementation of the invention, the actuating portion has an eccentric region, the eccentric region being operatively connected to the tensioning lever, in particular connected in a rotationally fixed manner. During a pivoting movement of the clamping lever, the eccentric region is thus also pivoted about an eccentric axis. The eccentric region bears against the clamping section, so that an eccentric stroke is transmitted from the eccentric region to the clamping section by a pivoting movement of the pivoting lever.

In a preferred embodiment of the invention, the clamping portion has a pressure leaf spring with a compression direction, wherein the compression direction is aligned in the clamping direction. The actuating portion and in particular the eccentric region act on the pressure leaf spring. The pressure leaf spring is preferably aligned perpendicular to the tensioning direction and convexly curved, with a center of curvature or maximum in the tensioning and / or compression direction. Preferably, the printing sheet spring is attached to one side or one end to the clamping portion, the other side of the printing sheet spring is free. During clamping of the clamping device, the eccentric region is rotated about the pivot axis of the clamping lever via the clamping lever, so that the eccentric stroke is exerted on the clamping section, in particular on the pressure plate spring. During clamping, the eccentric region slides along the pressure leaf spring in a direction perpendicular to the tensioning direction and / or compression direction, wherein the eccentric region during tensioning exceeds the maximum of the pressure leaf spring as a dead center. Once the eccentric has exceeded the dead center, this is arranged self-locking behind the dead center. In this way, on the one hand, the eccentric stroke can be exerted on the pressure leaf spring and move the second cover section relative to the first cover section in the tensioning direction. Secondly, the clamping device is self-locking, so that with a simple manual movement both the clamping and the locking can be implemented.

It is preferred that the clamping lid has a linear guide, wherein the linear guide is arranged in the first lid portion and the clamping portion linearly along the clamping direction. In this way, the clamping section can be moved in the clamping direction. Preferably, the linear guide is designed so that it holds the clamping portion captive.

It is particularly preferred that the clamping cover has at least one corner, preferably at some corners, in particular at all corners optionally one adjustment corner at a time. The Justageecke is arranged in a pivot plane parallel to the clamping lid pivotable on the first and the second cover portion. The adjustment corner assumes the function to match the inner contour of the transport box, in particular to the inner contour of the corner regions of the transport box, so that the clamping cover is securely clamped in the transport box.

Preferably, the clamping lid and / or the transport box are made of stainless steel. As a result, the durability of the transport arrangement is secured with respect to chemical attacks while maintaining high mechanical stability.

• 4 a clamping lid for a transport arrangement, as shown in the preceding figures in a three-dimensional representation.

The 1 shows a schematic, three-dimensional representation of a transport arrangement 1 as an embodiment of the invention. The transport arrangement 1 has a transport box 2 and a clamping lid 3 on. The clamping lid 3 is in the transport box 2 below an upper edge of the transport box 2 and / or in the interior of the transport box 2 arranged.

The transport box 2 has a rectangular base and has four walls 4a . b , c, d on, with the walls 4a . c as narrow sides and the walls 4b, d are formed as long sides. The walls 4a . b . c . d are closed all around. The walls 4a , b, c, d respectively form a corner region between them, the corner region each having an angle of Includes 90 degrees. The walls 4a . b . c . d are made of a perforated plate and have a plurality of through holes 5 on. A floor 6 of the transport box 2 can also be made of such a perforated plate. Perpendicular to the ground 6 is a height H defined, with the clamping cover 3 at any height H in the transport box 2 can be used.

At the upper open end or entrance of the transport box 2 this one has an end area 7 which is characterized by a rejuvenation. The 2 shows the transport arrangement 1 in a schematic side view, wherein it can be seen that the end region 7 over a circumferential collar 8th has, which in a plane perpendicular to the vertical extent to the height H is aligned and approximately congruent with the ground 6 is trained. Under the collar 8th is the transport box 2 on each of the walls 4a . b c . d tapered or narrower, so that it can be used on the rejuvenation automated. For example, the collar 8th be placed on a rail. Due to the design of the end region 7 is the transport box 2 in the direction of the height H formed undercut, wherein the undercut by the taper or offset in the region of the end portion 7 is formed.

The clamping lid 3 has in the tensioned state a longitudinal extent, which in a tensioning direction S of the clamping cover 3 is aligned, a length to a free length in the transport box 2 adjusted so that the clamping cover 3 in the transport box 2 is clamped and thereby at any height H can be fixed.

The function of the transport arrangement 1 It is that in the transport box parts, such as gear parts, bearings, balls, rolling elements, etc. can be inserted and by placing the clamping cover 3 can be secured according to any level, so that they also during a movement of the transport arrangement 1 stay free of charge. The clamping lid 3 can be tightened with a simple hand movement, as explained below. The perforated sheets or perforated sheet metal sections in the transport box 2 or in the walls 4a . b . c . d or soil 6 serve to leave a washing liquid to the parts.

The clamping lid 3 As best shown in the schematic plan view of FIG 3 it can be seen - a clamping device 10 on which on a first lid section 11 and a second lid portion 12 is arranged. More specifically, the tensioner has 10 an operating section 13 and a tensioning section 14 on. The operating section 13 is sliding on the first lid section 11 arranged. The tensioning section 14 is non-displaceable on the second lid portion 12 arranged. The first lid section 11 is formed as a rectangular plate, which in the transverse direction to the clamping direction S to the free interior of the transport box 2 is adjusted, so that the clamping cover 3 with play in the transport box 2 can be arranged.

In clamping direction S is the first lid section 11 however, compared to the free or open length in the transport box 2 shortened trained. The second lid section 12 closes in the clamping direction S to the first lid section 11 and overlaps with two tongues 16a . b with the first lid section 11 so as to ensure that the first lid portion 11 and the second lid section 12 can not rotate relative to each other, but mutually in the clamping direction S store in a sliding manner. In the first lid section 11 is a perforated sheet metal section 9 with passage openings 5 brought in.

The operating section 13 has a clamping lever 17 which is about a pivot axis A which are fixed in the first lid section 11 is arranged, can be pivoted. With the clamping lever 17 is an eccentric area 18 formed as a sheet metal section, rotatably connected, so with pivoting of the clamping lever 17 also the eccentric area 18 is pivoted. The eccentric region 18 has an actuating region 19 on, which in the radial direction to the pivot axis A compared with other neighboring areas and which is a curve K when swinging the clamping lever 17 around the pivot axis A describes.

The tensioning section 14 has a bar 20 on which perpendicular to the clamping direction S is aligned and which optionally linear or punctiform on the first lid portion 11 in tension direction S freely slidable rests. On the the operating section 13 facing side of the bar 20 a pressure leaf spring 21 is arranged, which on one side via screws 22 at the bar 20 is fixed and which has a convex profile, wherein the convex course a center of curvature 23 or maximum, which is centered on the pressure leaf spring 21 lies. In the center of curvature 23 has the pressure leaf spring 21 the largest distance to the bar 20 in tension direction S , When operating the clamping lever 17 becomes the eccentric area 18 , especially the operating area 19 along the curve K over the pressure leaf spring 21 guided. This is the clamping section 14 in tension direction S deflected or moved. By the displacement of the clamping section 14 becomes the first lid section 11 and the second lid portion 12 is pushed apart, so that both cover sections 11 . 12 against the walls 4a . c of the transport box 2 support.

When moving the clamping lever 17 moves the eccentric area 18 , especially the operating area 19 the pressure leaf spring 21 up to a central maximum and / or the center of curvature 23 from. In this position, a maximum deflection on the clamping section 14 transfer. At the same time, the center of curvature represents 23 a dead center for the eccentric area 18 , in particular the operating area 19 is, wherein in a further pivoting of the clamping lever 17 over the center of curvature 23 the dead center is exceeded and the tension lever 17 is arranged self-locking.

To the bar 20 closes a transmission link 24 which is designed as a rod, in particular as a push rod. The transmission link 24 is in a linear guide 25 guided, which on the first lid section 11 is fixed. The linear guide 25 is as a pipe guide for the transmission member 24 formed so that only a linear movement of the transfer member 24 is possible. By the edition of the bar 20 on the first cover section 11 can the tensioning section 14 not about the clamping direction S twisting around, through the linear guide 25 is also a lifting of the clamping section 14 effectively prevented. The other end of the transmission link 24 is over a log 15 on the second lid section 12 attached.

The 4 shows the clamping lid 3 in a schematic three-dimensional representation, being due to the other perspective in the 3 hidden sections can be recognized. In particular, in the 4 Justageecken 26 in an oblique view, with two of the adjustment corners 26 at the free corner regions of the first lid portion 11 and two adjustment corners 26 at the free corner regions of the second lid portion 12 are arranged. The adjustment corners 26 are each about an alignment axis J pivoted so that the adjustment corners 26 when tightening automatically at the corner of the transport box 2 can align. The adjustment corners 26 each have a slot area in which the corner regions of the lid sections 11 . 12 are introduced, so that the adjustment corners 26 exclusively in a pivot plane parallel to the surface extension of the clamping cover 3 around the respective alignment axis J can be pivoted. The possible pivoting angle is less than 20 °, in particular less than 15 °.

The operation of the transport arrangement 1 is as follows: In a first step, parts are in the transport box 2 inserted. In a second step, the clamping lid 3 in the transport box 2 inserted. A straight insertion of the clamping cover 3 is due to the undercut end region 7 of the transport box 2 not possible. In the second step, the clamping cover 3 rotated around a mounting axis, the center through the clamping lid 3 and parallel to the clamping direction S is arranged. As a result, the interference contour of the clamping cover 3 in the narrow direction of the transport box 2 sufficiently reduced to the clamping lid 3 to be able to introduce. In the longitudinal direction of the transport box 2 , parallel to the clamping direction S is the length of the clamping lid 3 so dimensioned that it can be introduced collision-free in the untensioned state.

After inserting the clamping cover 3 in the transport box, in a third step, this is behind the end area 7 parallel to the ground 6 aligned and on the parts in the transport box 2 so that they are secured.

In a fourth step, the clamping device 10 approved. By pivoting the clamping lever 17 parallel to the surface extension of the clamping cover 3 around the pivot axis A becomes the operating area 19 over the pressure leaf spring 21 guided, wherein the clamping section 14 in tension direction S is moved until the first and the second cover portion 11,12 with the Justageecken 26 in the corner areas of the transport box 2 issue. By further pivoting the clamping lever 17 becomes the clamping lid 17 braced and at the same time the pressure leaf spring 21 in the direction of the clamping direction S deflected. Once the actuation area 19 the center of curvature 23 the pressure leaf spring 21 has run over as dead center, has the clamping device 10 taken a self-locked state. The parts are then over the clamping cover 3 in the transport box 2 secured.

Subsequently, the parts in the transport arrangement 1 edited, so in particular to be washed, through the through holes 5 in the walls 4a . b . c . d , if necessary in the ground 6 and in the clamping lid 3 the washing liquid is passed through. After processing, especially washing, possibly dry, etc., the transport arrangement 1 be opened by pivoting the clamping lever 17 in the opposite direction to remove the parts ..
