Definitions

  • the invention relates to an apparatus for the assembly of a crate.
  • the invention also relates to a method for the assembly of a crate and the use of the apparatus and the method.
  • the apparatus is one of several apparatuses which are placed so that they form a carousel arrangement.
  • identical wood veneers are inserted in an apparatus on each their shelves in the frame, and are centred by a backstop on the apparatus.
  • the press cylinder is activated and set for a predetermined vertical upwards movement of the lowermost metal plate, which thus presses the frames together and herewith also the veneers. This is effected under a predetermined temperature.
  • the veneers land on a removal station.
  • the pressing/drying time thus corresponds to a revolution of the carousel, and each frame with veneers thus receives a uniform treatment. Consequently, this known technique does not involve a method for the assembly of a crate.
  • the object of the apparatus used is not to exercise a pressure on a crate which is to be assembled, and where it is expedient for the pressure exercised to be distributed evenly on the crate so that this does not become askew. Means are not provided for the stabilisation of the crate so that this does not slide, and upon damage to the one column a non-uniform pressure is applied.
  • the positioning of the press cylinder, and herewith the direction of movement for the transfer of forces to the lowermost metal plate so that this can be pressed against the uppermost metal plate, will demand a considerable amount of energy, which renders the pressing costly.
  • the apparatus comprises at least one press, where said press comprises at least two, substantially horizontal, separated plates, an upper plate/an upper ram and a bottom plate for the provision of an opening for the insertion of the crate, said crate being placed on the bottom plate, and said upper plate/said upper ram being mounted on a ver- tically-displaceable cylinder rod, the movement of which is brought about by control means, said cylinder rod being mounted on a press cylinder, and said apparatus further comprising positioning means comprising at least one vertical adjustment means which is set for a predetermined position.
  • the apparatus will function in such a manner that when the desired crate is placed on the bottom plate, the apparatus' positioning means will result not only in the crate lying centred and firmly on the bottom plate, but also in the press cylinder being fastened to the securing means in such a manner that the upper plate/the upper ram, mounted on the movable arrangement, by virtue of the control means brings about a downwards-directed vertical movement which establishes the correct pressure for the positioned crate.
  • the upper plate/the upper ram can thus form an integrated part with the press cylinder, whereby the construction is simplified.
  • the crate can assume different sizes, regardless of which it can be placed symmetrically on the bottom plate and in relation to the upper plate/the upper ram.
  • the height of the press cylinder can be adjusted so that a vertical pressure is established which corresponds to the height of the crate, and without the pressure becoming too high or too low.
  • the invention also relates to a system such as disclosed in claim 8.
  • the invention also relates to a method for the assembly of a crate in a press, characterised by the press comprising at least two substantially horizontal, separated plates, an upper plate/an upper ram and a bottom plate, for the provision of an opening for the insertion of the crate, said crate being placed on the bottom plate, and
  • the adhesive which has possibly been used during the assembly of the part elements, receives the correct drying time, and that the crate receives the correct compression time so that it does not fall apart after a short period of use. Moreover, adjustments can be made in accordance with the type of adhesive which is used.
  • fig. 1 shows an apparatus according to the invention for the exercising of a pressure on a crate
  • fig. 2 shows the apparatus in fig. 1 seen from the side
  • fig. 3 shows a system according to the invention for exercising a pressure on a crate, seen from above,
  • fig. 4 shows a section-divided cross-section taken along line A-A of the system shown in fig. 3,
  • fig. 5 shows an example of the assembly of a crate which is to be pressed by the apparatus according to the invention.
  • Figure 1 shows an apparatus 1 according to the invention for exercising a pressure on a crate 2, comprising a press 3, said press 3 comprising two horizontal, separated plates, a bottom plate 5 and an upper plate/an upper ram 4, and a press cylinder 7, said press cylinder 7 being fastened to a securing means 8 comprising a column.
  • the upper plate/the upper ram 4 comprises a substantially horizontal, rectangular plate, which in length and breadth is symmetrically mounted on a movable arrangement 12 comprising a cylinder rod. Disposed symmetrically on the upper side 4', facing towards the cylinder rod 12, there are two slide plates/bushes 14 which, facing towards the column 8, extend out from the upper plate/the upper ram 4 (see fig. 2) and surround two vertical tubes which are placed on each side of the column 8, said vertical tubes serving as a backstop (13). When the upper plate/the upper ram 4 is displaced vertically, the slide plates 14 will slide along the vertical tubes so that this stabilises the movement of the upper plate/the upper ram 4.
  • the cylinder rod 12 is secured elastically to the upper side 4', in that on the underside and upper side of this there is laid an elastic disk, for example of rubber, against which a nut is locked.
  • the nut is not tightened, since the result would be that no movement could arise between the ram 4 and the cylindrical rod 12.
  • the flexibility is important in order to achieve uniform pressure on the upper side of a crate which is sloping and/or uneven.
  • Each backstop 13 is fastened at the one end 13' to a top plate 15, said top plate 15 being further fastened to the column 8, and at the other end 13" is fastened to the rear 5' (see fig. 2) of the bottom plate.
  • the bottom plate 5 which is stationary and mounted symmetrically to the column 8, comprises a surface part 5" which is parallel to the upper plate/the upper ram 4, and a front part 5'".
  • a holder 18 for additional stabilisation of the crate 2, in extension of the rear 5' of the bottom plate there is mounted a holder 18 (see fig. 2) in which there is fastened a horizontal control means
  • the end stop 10 consists of a single tube, where this is shaped to comprise a horizontal part 10' which is fastened to the holder 18 and extends parallel with the surface part 5" of the bottom plate, a vertical part 10" which is at right-angles to the horizontal part 10' and facing upwards, and a transverse part 10'" which extends transversely to and parallel with the surface part 5" of the bottom plate.
  • the end stop 10 can be adjusted lengthways, whereby the positioned crate 2 can be centred in relation to the upper plate/the upper ram 4 and is thus exposed to a uniform pressure.
  • Figure 2 shows the apparatus 1 shown in fig. 1 seen from the side, comprising a column 8, a bottom plate 5, an end stop 10 and a press cylinder 7 with an upper plate/ram 4 mounted on the cylinder rod 12.
  • the press cylinder 7 is placed in a cylinder suspension which is fastened by a locking bolt 17 to the column's vertical adjustment means 11 comprising through-going holes.
  • a locking bolt 17 to the column's vertical adjustment means 11 comprising through-going holes.
  • the press cylinder 7 and the cylinder rod are primarily a pneumatic arrangement, where a given air pressure will give rise to a pressure exerted by the ram 4.
  • a table can thus be drawn up from which the machine can be pre-set for a given task.
  • Projections 20 are provided on the rear 8' of the column, so that the column 8 can, for example, be mounted on a frame or a wall.
  • Figure 3 shows a system 21 according to the invention, seen from above, for the execution of a pressure on a crate.
  • the system 21 comprises eight identical apparatuses 1 , where these are coupled together so that they form a carousel.
  • the apparatuses 1 are fastened to a frame 22 via the projection 20 (see also fig. 2 or 4), and to support columns 23 via the top plate 15 (see fig. 2 or 3). It can be en- visaged, however, that the apparatuses 1 can be coupled together in another manner, for example in a long row.
  • the carousel can be turned manually or automatically by a control means 9 on the front part 5"' of the bottom plate. With the placing of a crate from a predetermined place, the compression time for the crate will hereby correspond to one revolution of the carousel.
  • Figure 4 shows a section-divided cross-section taken along line A-A of the system 21 shown in fig. 3.
  • a vibration damper 24 is mounted in extension of the column 8 and directed towards the bottom plate 5.
  • a roller arrangement 25 which, with the mentioned manual turning, will enable the apparatus 1 to roll to the next position.
  • Figure 5 shows the method of assembly for a crate which is to be pressed by the apparatus 1 according to the invention.
  • the crate consists of individual parts of wood comprising two side pieces 25, two end pieces 26, a bottom plate 27 and a top plate (not shown in the drawing).
  • each side piece 25 comprises two grooves, a lower groove 28 and an upper groove 29, said grooves forming a slide-way for the bottom plate 27.
  • two dowel holes 31 are drilled between the grooves 28,29.
  • the end pieces 26 are provided with two dowels 33 which, during the assembly, are brought into engagement with the dowel holes 31 in the side pieces.
  • Other principles of assembly can be used. In the assembly of the crate, which is effected manually, the joints will thus be established only on two opposing sides, which simplifies the assembly. In the pressing process, the wooden crate is thus placed with the joints partly facing towards the upper plate/the upper ram 4 and partly towards the bottom plate 5 (see also fig. 2). Pressure thus needs only to be established from a single direction for production of a fully-assembled crate.
  • the mentioned parts of the crate, side pieces 25, end pieces 26, the bottom plate 27 and the top plate, can be either rectangular or square.
  • the end pieces 26 can be provided with lower grooves 28, so that the bottom plate 27 rests against these grooves.
  • the crate can be made, for example, of plastic or other hard material.
