Abstract
The mounting of pelt board inner bags (4), which typically consist of a tubular bag/wrapper of fat absorbing material, the geometry and circumference of which correspond to an expansion pelt board, is in accordance with the presently known technique carried out manually, i.e. a person takes old of a pelt board inner bag (4) and draws the bag on and over the expansion pelt board (4) to a desired position on the board, after which this is ready for the mounting of a pelt for taning. Seen in the fight of the typical number of bags which shall be mounted on the boards during the course of a pelt processing season, this manual work constitutes a great many hours of manual work which is monotonous and which contributes towards making the production of furs an expensive undertaking. There is thus disclosed a method and an arrangement (2) for the automating of the mounting of a pelt board inner bag (4) on an expansion pelt board (6) with a nose end/pointed end (60) and a foot end (9), and a locking/distension element (11) which comprises a blunt part (7) which from the foot end extends in the longitudinal direction of the board, in which the expansion pelt board (6) is fastened in the upright position opposite a bag mounting area (16) by the arrangement (2).
Description
Title: Method and arrangement for mounting a pelt board inner bag on an expansion pelt board.
The present invention relates to a method for the mounting of a pelt board in- πer bag on a distension element, namely an expandable and collapsible distension element/pelt board, a so-called expansion pelt board, with a convex and open surface structure, a nose end and foot end, and a locking/distension element which comprises a blunt extending part extending from the foot end in the longitudinal direction of the pelt board, in which an expansion pelt board is fastened in an up- right position opposite a bag mounting area.
The invention also relates to an arrangement for the execution of the method according to the invention.
An expandable and collapsible distension element/pelt board, in the following called an expansion pelt board, is disclosed in WO2005/026394, and can be described as a distension element/pelt board which has a longitudinal axis, a first transverse axis (breadth axis) and a second transverse axis (height axis), a front end for engaging the nose end of a pelt, and a foot end which is preferably termi- nated at right-angles in relation to the longitudinal axis of the board, and where the distension element/the board has at least a first and a second convex surface with an open structure which defines a cavity, and where said surfaces of the board are configured in a substantially symmetrical manner around at least two of the defined axes, and where the board comprises at least one opening to the cavity in the foot end. The distension element/board typically consists in practice of two elongated half-shells with convex surfaces with open structure, which in combination with a displaceable locking and distension element in the board's longitudinal direction form a cavity from which the air under the open structure can be changed via an opening in the foot end during the drying process.
The convex configuration of the surface of the distension element in combination with its open structure has the result that the fastening of a pelt stretched on the distension element/pelt board of the type described here can be established by a holding bag or by wrapping, which after the pelt is stretched on the board is drawn over the fur side of the pelt and drawn towards the foot end of the board, so that at relevant areas of the pelt board the bag applies pressure which presses the leather side of the pelt against the convex open structures, whereby sufficient fric-
tion is created to enable the pelt to be fastened in the stretched position during the whole of the subsequent drying procedure.
The use of staples and other pelt-damaging holding means is hereby ren- dered superfluous, which means that the price for pelts dried on the newly- developed pelt boards is higher, with subsequent economic benefits for the seller.
The displaceable locking and distension element is displaceable between a forward position, where the distension element has its greatest circumference, and is the position in which the locking and distension element are in during the taning and drying of pelts, and a drawn-back position where the expansion pelt board is "collapsed", so that the faces edges of the expansion board are in contact with each other. This results in a reduction of the expansion board's circumference, which is a very great advantage when the pelt shall subsequently be removed from the board, in that the work of pulling the pelt free from the surfaces of the board is considerably reduced, whereby the dried pelt is easy to remove.
In the removal of the pelt from the board, there is thus effected a displacement of the locking and distension element to the drawn-back position, whereby the expansion pelt board "collapses" with a subsequent smaller reduction in the circumference of the board, whereby the work of pulling the dried pelt from the collapsed expansion board is eased to a significant degree, as compared with the pulling-free of a dried pelt from a conventional pelt board.
The expansion board's locking and distension element also comprises a blunt part extending from the foot end of the distension element/pelt board, and which herewith provides an engagement area for holding means and the like which are used in connection with the fastening and handling of the expansion board, and in connection with the displacement of the locking and distension ele- ment between the drawn-back position and the forward position and vice versa.
With the object of being able to remove possible fat on the leather side of the pelt during the drying process, a layer of fat-absorbing material can in certain cases be placed between the convex open-structured surface of the board, which material is placed on the board before the drawing-over of the pelt. This material can typically be a bag made of fat-absorbing material, chiefly fat-absorbing paper with perforations, for example in the form of a so-called pelt board inner bag,
which will thus be lying between the surface of the board and the leather side of the pelt
The subsequent drying of the pelt takes place in a drying unit comprising a carriage, the bed of which is built up as an air induction channel with a blower, where the upwardly-facing side surface comprises openings for accommodation of the blunt extending part on the locking and distension element, which is extending from the foot end of the expansion board with the pelt mounted, which is inserted into the drying unit for drying. The drying then takes place by placing the drying unit in a room with conditioned air, where the blower is activated, whereby a continuous exchanging of the air in the expansion board's cavity is effected via the air induction openings in the immediate vicinity of the openings for receiving the blunt extending parts on the locking and distension elements. The expansion pelt boards are placed and fastened in the drying unit in the upright position.
In addition to the advantages already mentioned, the expansion boards have the advantage that the handling of the pelt boards after the drying of the pelts is relatively limited, in that after the pelts have been mounted on the expansion pelt boards, these are transferred directly to the drying unit, after which this can be placed in the drying room with the desired air temperature and humidity, and the blowing of air into the cavities in the boards can commence by activation of the drying unit's blower. The pelts are thus dried on the boards, which as described earlier are placed standing upright from the bed of the drying unit, and after drying of the pelts the boards are conveyed for removal of the boards from the unit.
The expansion pelt board typically appears in two configurations, a first configuration, which is intended for use in the mounting and drying of pelts from male animals, is elongated in fashion, and the extent of the board in relation to the longitudinal axis in the direction of the first transverse axis and the second transverse axis is more or less uniformly decreasing in the direction towards the front end, which is pointed but rounded-off, extending from an area of the expansion element near the foot end, where the extent of this around the first and the second transverse axis is more or less constant. Such a pelt board is thus referred to as a "male pelt board".
Expansion pelt boards intended for use in the mounting and drying of pelts from female animals are of a second configuration, but have the same fashion as those described above for male animals except that they are shorter, in that the
boards for pelts from female animals do not comprise the area near the foot end, where the extent of this around the first and the second transverse axes is more or less constant. Such a board is thus referred to as a "female pelt board".
In the following, the "taning" of a pelt is to be understood as a process consisting of the following: the mounting of a pelt on the board, chiefly with the leather side of the pelt facing towards the surface of the board, the stretching of the pelt on the board, and the fastening of the pelt in the stretched position on the board with the use of one or more types of holding means.
In the following, a "taned" pelt shall be understood to be a pelt drawn on to the pelt board, stretched on the board and fastened in this position by one or more holding means.
The term "drying procedure" or drying of the pelt shall be understood to be a drying of the leather side of the pelt to a preferred degree whereby attack by mites is known from experience to be excluded. The drying procedure is typically carried out by a continuous changing of the air in the cavity in the board by the blowing-in of dry air.
In the following, the "removal" of a pelt shall be understood to be the removing of a pelt which has been mounted, stretched and fastened in this position on the board during the drying procedure, typically after the pelt drying process has been concluded. The removal procedure also comprises the removal of any means which have been used for fastening the pelt in the stretched position on the pelt board.
The expansion pelt boards are developed to be able to be used a large number of times, and with the improved drying characteristics which are offered by these boards, the boards will be reused up to several times during the course of a pelt processing period.
When the dried pelt and the holding bag and pelt board inner bag have been removed, the pelt board is thus ready for reuse, but before a new pelt is mounted on the board for stretching (taning), it will be necessary to provide the board with a new inner bag so that the possibility is hereby provided for the removal of fat from the leather side of the pelt during the drying.
The mounting of such pelt board inner bags, which typically comprise a tubular bag, wrapper, the geometry of which corresponds to that of the expansion board, is with regard to the known technique at present carried out manually, i.e. a person takes hold of a pelt board inner bag and draws it over to a desired position on the expansion board, after which this is ready for the mounting of a pelt for tan- ing. However, this manual work would perhaps immediately appear to be work which can be overcome, but seen in the light of the typical number of bags which shall be mounted on the pelt boards during the course of a pelt processing season, what is actually involved is a large number of hours of manual work which is monotonous and which contributes towards making the production of furs an expensive operation.
In DK 175 405 B1 there is disclosed a method and apparatus for the mounting of pelts, e.g. mink pelts on a pelt board, where the pelt board bag is mounted on a traditional pelt board of wood disposed in a horizontal manner. However, the method and the apparatus are not suitable for the mounting of a pelt board bag on an expansion pelt board.
It is thus the object of the invention to provide a method for the automation of the mounting on a pelt board inner bag on a distension element/pelt board, namely an expandable and collapsible distension element/pelt board, a so-called expansion pelt board, with a convex and open surface structure, a nose end and a foot end, and a locking/distension element which from the foot end and oriented in the longitudinal direction comprises a blunt extending part in which an expansion pelt board is fastened in the upright position opposite a bag mounting area.
With the invention it is realised that this object can be achieved by the implementation of the following operations:
- turning of a rocker arm with first bag gripping arrangements which can be activated for displacement from a substantially vertical start position to a horizontal position for contact with the first side of a relevant pelt board inner bag facing towards the bag gripping arrangements from a stack of supplied inner bags,
- collection of a pelt board inner bag from the stack of supplied bags by activation of the first bag gripping arrangements, and displacement of the rocker arm to a vertically-oriented position over the pointed end of the expansion pelt board,
- preparation of opening of the lower ends of the pelt board inner bag by displacement of further gripping arrangements for contact against the opposing sec-
ond side of the pelt board inner bag, and subsequent activation of the further gripping arrangements,
- opening of the lower ends of the pelt board inner bag for introduction of the pointed end of the board into the opening by implementing a relative displacement away from each other, between the first bag gripping arrangements and the further activatable gripping arrangements,
.- mounting of the pelt board inner bag on the expansion pelt board by displacement of the rocker arm and activation of the further gripping arrangements downwards to a preferred stop point, - de-activation of the first bag gripping arrangements and the further gripping arrangements,
- displacement of the rocker arm and the further gripping arrangements to the start position.
An arrangement for the execution of the method according to the invention is characterised in that it comprises an upright console extending from an under layer, and having a column with a front side oriented towards a bag mounting area, and a rear side, and a first side and a second side, where the first side, out from the rear side, comprises an extending, substantially horizontal, partly open, elongated, box-shaped shelf for a supply of stacked pelt board inner bags, and a substantially vertical guide rail for the guiding of the carriage on the second side of the column which can be displaced by a first actuator in the direction of the guide rail, said carriage comprising a mounting plate extending out from the front side of the column and comprising with a second actuator cooperating with the supply of pelt board inner bags a rocker arm, the side of which oriented towards the supply of pelt board bags comprises first bag gripping arrangements for engaging and collecting-up of the pelt board inner bag lying uppermost in the supply of bags, and said mounting plate between the carriage and the first actuator comprising a vertically-oriented, upright part comprising further displaceable gripping arrangements which can be activated for engaging against the wall of an actual pelt board inner bag opposite that side of the inner bag which is in engagement with the first bag gripping arrangements on the rocker arm.
There is hereby disclosed an arrangement for the execution of the method according to the invention, where a bag is mounted on an expansion pelt board which is placed upright in the bag mounting area, where by activation of the second actuator the arrangement carries out a tilting of the rocker arm in over the stack of pelt board inner bags lying in a supply, followed by an activation of the
first bag gripping arrangements, whereby the inner bag lying uppermost is engaged by the rocker arm, which is then swung up to a vertical position, after which an opening of the mouth of the pelt board inner bag is effected by displacement of the further gripping arrangements so that these are placed at the wall of the bag, opposite the first bag gripping arrangements, where the further gripping arrangements are activated and engage the wall of the pelt board inner bag, after which the further gripping arrangements are displaced a smaller distance away from the rocker arm, whereby the downwardly-facing end of the tubular pelt board inner bag is opened, after which the carriage, by activation of the first actuator, is displaced down towards the under layer, whereby the pelt board inner bag is led down to a desired position over the pointed end of the upright-standing expansion pelt board which is placed in the bag mounting area, after which the first bag gripping arrangements and the further gripping arrangements are de-activated, and the carriage is displaced by activation of the first actuator in the opposite direction to the starting point, and then the further gripping arrangements are displaced to a start position outside the operational plane of the rocker arm.
It is further preferred that the rocker arm at the second actuator is pivotal between a first position where the side of the rocker arm oriented towards the supply side of stacked inner bags is substantially parallel with the column, and a second position where the said side of the rocker arm is extending substantially parallel with the bottom of the box-shaped shelf.
Since the opening of the lower end of the pelt board inner bag, which is es- tablished by cooperation between the first bag gripping arrangements and the further bag gripping arrangements, is relatively small, combined with the fact that not all of the upright-standing expansion pelt boards are standing up from the securing point in a uniform manner, in certain cases there can arise the problem that the mouth of the inner bag can obtain a grip on the pointed end of the board, which can damage the bag, which is typically made of fat-absorbing paper cardboard or paper. Moreover, cases can arise where the expansion pelt board is standing so crookedly up from the securing point that in the feeding down of the bag, the mouth of the bag is led past the pointed end of the board, which means that the inner bag is not mounted on the expansion pelt board, which is very inexpedient.
With the object of ensuring that the bag collected by the first bag gripping arrangements and opened by means of the further gripping arrangements is correctly led down over the relevant upright-standing expansion pelt board, the free
end of the mounting plate can comprise a guide arrangement for the guiding-in of the pointed end of the board to a preferred position in relation to the rocker arm, said guide arrangement being disposed down under the rocker arm.
Without denouncing the right to other configurations of the guide arrangement for the above-mentioned guiding-in according to the invention, it can be mentioned that the guide arrangement can with advantage consist of a two-part control claw, the arms of which are mutually displaceabie, and where the sides facing each other are V-shaped, and which on the downwardly-facing side edge com- prise outwardly-inclining webs, which in combination form a funnel-shaped opening disposed immediately below the pelt board inner bag opened under the influence of the first bag gripping arrangements and the further bag gripping arrangements, for the guiding-in of the pointed end of the expansion pelt board between the facing V-shaped sides of the arms, and where the arms are connected to a third actuator for implementation of a relative displacement between the arms between a passive position where the V-shaped sides of the control claw are in contact with the surface of the relevant pelt board, and an open position where said V- shaped sides are placed in a position at a distance from the surface of the expansion pelt board.
It is hereby ensured that the pointed end of the expansion pelt board is brought into the desired bag mounting position before the pelt board inner bag is led down over the board to the preferred position by displacement of the carriage, and it is hereby also ensured that all expansion pelt boards which are fed to the bag mounting area are provided with a pelt board inner bag.
Without denouncing the right to the use of other bag gripping devices in connection with the arrangement according to the invention, it can be mentioned that the first bag gripping arrangements on the rocker arm can with advantage consist of at least two spaced suction cups which can be activated.
Without denouncing the right to the use of other bag gripping devices in connection with the arrangement according to the invention, it can be mentioned that the further displaceabie gripping means can with advantage consist of at least one suction cup transversely displaceabie in relation to the front plane of the column by a fourth actuator, and where by a fifth actuator, which is housed on the mounting plate, said fourth actuator is displaceabie parallel with the front plane of the column.
In the following, the invention is explained in more detail with reference to the drawing, where

Fig. 6 is a frontal picture of the arrangement shown in fig.5, during the mounting of a pelt board inner bag on an expansion pelt board.
In fig. 1 there is shown a first embodiment of an arrangement 2 for the mounting of pelt board inner bags 4 on an expansion pelt board 6.
The arrangement two comprises a console 10 standing upright from an under layer 8 and with a column 12 with a front side 14 oriented towards a bag mounting area 16, and a rear side 18, a first side 20 and a second side 22 cf. also fig. 2 and fig. 3.
The first side 20 and the column 12 comprise an extending, substantially horizontal and standing out from the rear side 18 an open, elongated, box-shaped shelf 24 for a supply of stacked pelt board inner bags 4.
As will appear from fig.3, the second side 22 of the column 12 comprises a substantially vertical guide rail 28 for the guiding of a carriage 32 displaceable by a first actuator 30 in the direction of the guide rail. Extending out from the front side 14, the carriage 32 comprises a mounting plate 34 comprising a rocker arm 38 displaceable by a second actuator 36 and whose side 40 oriented towards the supply 26 of pelt board inner bags 4 comprises first bag gripping arrangements 42 in the form of three spaced suction cups 42 which can be activated for engaging and collecting the uppermost lying inner bag 4 from the supply 26, in that the arm 38 can be tilted in a vertical plane 44 along the centre axis 45 of the supply and in over the supply 26, as indicated in fig. 1.
Between the carriage 32 and the second actuator 36 the mounting plate 34 comprises a vertically upstanding part 46 on which there is housed a fourth actuator in the form of two pistons 48 with operation direction parallel with the front side 14 of the column 12, and in the free 49 end of which there is provided an angle bracket 50 on which there is a further fifth actuator 51 with operation direction transversely to the front side 14 of the column 12, respectively towards and away from the rocker arm 38, similarly in the form of a piston which carries gripping arrangements 52 in the form of a suction cup 52, as will appear from the embodi- ment of the arrangement 2 shown in fig. 2, fig. 4 and fig. 6, or several suction cups 52 as will appear from the embodiment of the arrangement 2 according to the invention as shown in fig. 1 , for engaging towards the wall 54 of an actual pelt board inner bag 4 opposite that side 56 of the inner bag, which is in engagement with the first bag gripping arrangements 42 on the rocker arm 38, as illustrated in fig. 2. The gripping elements 52 are intended for the spreading of the opening of the lower end 58 of the pelt board inner bag 4, so that this, by a subsequent displacement of the carriage 32 by activation of the first actuator 30 in the direction towards the pointed end of the board 60, is opened for the receiving of the bag.
As will further appear from the embodiment of the arrangement 2 according to the invention shown in fig. 2, the free end 62 of the mounting plate 34 comprises a guide arrangement 64 for guiding the pointed end 60 of the board into a preferred position in relation to the rocker arm 38, said guide arrangement 64 being disposed down under the rocker arm.
As will appear from the embodiment of the arrangement 2 according to the invention shown in fig. 2 and fig. 4, the guide arrangement 64 consists of a two- part guide claw 66, the arms 68, 68'of which are mutually displaceable, and the
sides 70, 70' of which facing each other have a V-shaped fashion, which on the downwardly-facing side edge 72, 72'comprises outwardly-inclined lobes 74, 74\which in combination form a funnel-shaped opening 76 lying immediately below the pelt board inner bag 4 which is opened by the first gripping arrangements 42 and further gripping arrangements 52 for the guiding-in of the pointed end 60 of an expansion pelt board 6 between the facing V-shaped sides 70, 70 'of the arms 68, 68'.
The arms 68, 68'are connected to a third actuator 78 for carrying out a rela- tive displacement between the arms between a passive position where the facing V-shaped sides 70, 70' of the guide claw are in contact with the surface 80 of a relevant expansion pelt board 6, and an open position where said V-shaped sides are placed in a position at a distance from the surface of the expansion pelt board. This hereby enables a displacement of the guide arrangement 64 past the board inner bag 4 placed on the surface 80 of the board, without touching this, by displacement of the carriage 32 back to the start position for the collecting of a new pelt board inner bag 4 from the supply of inner bags 24.
In fig. 6 there is shown an embodiment of the arrangement 2 according to the invention where the guide arrangement 64 consists of an angle plate 82 which is mounted on the underside of a horizontal part 84 of the rocker arm 38.
Fig. 1 shows a more simple embodiment of the arrangement 2 according to the invention which does not have the guide arrangement 64 for guiding the pointed end 60 of the pelt board into a desired bag mounting position. This embodiment of the arrangement 2 requires a very precise positioning and stable fastening of the expansion pelt board 6 in the upright position.
The arrangement for the mounting of pelt board inner bags 4 on expansion pelt boards 6 placed in the upright position in the bag mounting area 16 functions in the following manner:
An expansion pelt board 6 fastened in a blunt extending part 7 at the foot end 9 in a supply arrangement 11 is displaced to a stop in the bag mounting area 16. The rocker arm 28 is displaced by the second actuator 36 in over the shelf 24 with the supply of pelt board inner bags 4, so that the bag gripping arrangements/suction cups 42 are brought into contact with the upwardly-facing side of the inner bag 4 lying uppermost in the supply 26. Hereafter, the suction cups are
activated so that side of the inner bag 4 facing these is engaged, after which the rocker arm 38 now carrying the collected inner bag 4 is swung by activation of the actuator 36 to a vertical position (cf. fig. 5, which shows the arrangement 2 during the swinging of the rocker arm 38), so that the inner bag 4 is now positioned over the pointed end 60 of an expansion pelt board 6.
The lower end 58 of the pelt board inner bag 4 is then opened by displacement of the further gripping means 52 in the form of one or more suction cups 52 by activation of the fourth actuator/pistons 48, so that these are now placed in the immediate vicinity of that side of the inner bag which faces away from the bag gripping arrangements 42. Hereafter, the further gripping means/suction cups are brought into contact with the said side of the inner bag 4 by means of the fifth actuator 51 , and activated so that the wall of this bag is engaged by the gripping means/suction cup(s) 52, after which the fifth actuator is displaced in a direction away from the rocker arm 38, whereby the lower end 58 of the pelt board inner bag 4 is now opened for receiving the pointed end 60 of the expansion pelt board 6. With the subsequent activation of the first actuator 30, the carriage 32 is displaced downwards in the direction towards the under layer 8, at the same time that the pointed end 60 of the board, in the cases where the arrangement 2 comprises a guide arrangement for guiding the pointed end 60 of the board into the desired bag mounting position for the inner bag 4 in the bag mounting area 16, is caught up in the funnel-shaped opening 76 and is received between the V-shaped sides 70, 70'of the arms 68, 68', alternatively by the angle plate 82 (cf. fig. 6), where the pointed end 60 of the pelt board is placed and fastened in an optimal position under the opened lower end 58 of the pelt board inner bag 4. The carriage is dis- placed downwards to a desired position, after which the bag gripping means/the suction cups 42 and the further gripping means 52 are deactivated and the latter displaced back towards the front side 14 of the column 12, so that these come free of the pelt board inner bag 4 now mounted on the expansion pelt board 6, at the same time that the arms 68, 68 'are displaced by the third actuator 78 away from each other, so that also these are freed from the inner bag 4 mounted on the expansion pelt board 6, after which the carriage 32, by activation of the actuator 30, is displaced upwards to its start position, after which the procedure is repeated after a new expansion pelt board 6 has been fed to the bag mounting area 16.
With the invention there is thus disclosed a method and an arrangement for the fully-automatic mounting of pelt board inner bags 4 on upright expansion pelt boards 6 in a bag mounting area 16, which will render the use of manual labour for this monotonous work superfluous, which will result in possibilities of saving man-
ual labour in connection with the work procedures involved in the processing of pelts.
