Definitions

  • the invention relates to a device for applying a rectangular frame consisting of angled profiles around the upper rim of a pallet.
  • a pallet When a pallet is used for the transport of cans, these cans are positioned in a number of layers, whereafter a rectangular frame consisting of angled profiles is positioned around and onto the upper layer of cans. This frame is connected to the pallet in one way or another in order to prevent that cans may drop from the pallet during transport.
  • the frame is lifted, whereafter the cans can be taken away. Thereafter the frame is placed on the pallet and preferably in such a way that the frame extends around and onto the upper rim of the pallet. This assembly can be passed to a storage yard till it is used again.
  • the object of the invention is to remove these disadvantages and to that end provides a device which is characterized in that the device comprises a mainly rectangular horizontally positioned frame work, within which said frame and said pallet can be positioned the one above the other, and at least four centring means spaced apart around the four sides of said frame work, each of said centring means consisting of an upper and a lower centring member, said upper and lower centring members being pivotally mounted to shafts connected to said frame work and running parallel to each other and in horizontally planes one above the other, each of said upper centring members comprising a leg extending downwards from its pivot shaft and the lower portion of said leg extending mainly inwardly into said frame work for obtaining a guiding cam for the frame to be handled, which leg can be, by mechanical means pivoted between a position in which the distance between the guiding cams of two opposite upper centring members is smaller than the width of the frame to be handled and a position in which this distance is such that the frame may pass said upper centring members, each of said lower centring members
  • a frame When using a device according to the present invention a frame will be brought downwardly onto the guiding cams of the upper centring means when the legs of these are extending substantially vertically downwards from the pivot shafts.
  • the frame By said guiding cams the frame will be centred and will move along the guiding cams downwardly onto the support surfaces of the lower centring members.
  • the leaf springs of these lower centring means will be positioned within the angled profiles of said frame and will be at some distance from the related profile.
  • a pallet is moved upwardly to the frame and during this it is guided by the leaf springs which are gradually biased towards the inner side walls of the frame. In this way a proper guidance of the pallet is obtained so that the frame will fit over it in the right way.
  • the lower surface of the cam of the leg of the upper centring member has the shape of a circle segment, such that this circular portion, in the most inwardly pivoted position of said upper centring member, will be present above the support surface of the lower centring member when this member is pivoted to its most outwardly position in respect of the frame work.
  • the circular portions of the upper centring members can be brought above the frame. In this way it is avoided that the frame is lifted by the pallet before the pallet is completely moved into the frame.
  • Pivoting of the leg might be used as well to check whether the frame has come to rest on the support surfaces of the lower centring members. If the framework should still be present, either completely or partly, on the legs of the upper centring members, no inward pivoting of all the legs would be possible and the device might be stopped.
  • the lower centring member comprises two side plates with a support block between them, said block carrying the leaf spring and being pivotable in respect of the side plates and being biased by means of a spring to a pivoted position inwardly of the frame, the rotation of said block being limited by abutments, said side plates being positioned on either side of the leg of an upper centring member.
  • side plates of the lower centring member will be outwardly pivotable in order to bring the leaf spring outside the formed assembly of pallet and frame so that this assembly can be removed out of the device downwards.
  • DE-A 3 143 093 a device is known for bringing a rectangular lid onto a box positioned on a fixed support. To that end the upper edge of the side walls of the box are pressed inwardly by means of rotatable supported cams. Said cams are biased towards the position in which they are pressing the upper edge of the side walls of the box inwardly and are moved downward by the lid which is applied on the box from above. So this device is only suitable for bringing a lid onto a box made from a flexible material such as cardboard or such like. So the known device is not suitable for bringing a rectangular frame onto a stiff pallet as is the aim of the present invention.
  • the figures 1-3 show the centring means of a device according to the invention comprising an upper centring member 1 and a lower centring member 2.
  • the upper centring member 1 is pivotable around a shaft 4 over an angle p shown in Fg. 2, for example by means of a pneumatic cylinder 3.
  • the angle p will be 45° at the most.
  • the upper centring member 1 substantially comprises the leg 7 with a cam portion 8, the upper surface 9 of which is forming a guide for the angled profiles 6 of the frame 5.
  • the lower centring member 2 comprises the side plates 10, as in particular appears from Fig. 5, a protruding portion 11 of said plates being pivotable supported by means of the shaft 12, while pivoting can take place by means of the pneumatic cylinder 13.
  • the support block 14 is composed of the parts 16 and 17 between which the leaf spring 18 is clamped by means of the screws 19, which are screwed into the part 16.
  • the support block 14 is biased to the position shown in Fig. 1 by means of a spring 20, the other end of which is connected to the protruding portion 11. In said position a protruding portion 21 of the support block 14 engages an abutment 22 of a side plate 10.
  • the side plates 10 each are provided with an oblique surface 24 near its upper end, said surfaces serving to guide a frame 5 and joining a support surface 25 on which the lower rim of the frame can come to rest.
  • the support block 14 may be pivoted in the direction of arrow P over an angle 8 of about 25 ° while the related side plates 10 can be pivoted around the shaft 12 over an angle y, as is in particular shown in Fig. 3.
  • the angle y will be 45° at the most.
  • a pallet 26 is moved from below into the device in the direction of the arrow B by means not shown in detail.
  • the side surfaces 27 of the pallet 26 initially engage the support block 14 and thereafter the leaf springs 18 extending from this block, so that the block 14 will be pivoted in the direction of the arrow P against the force of the spring 20.
  • the leaf springs 18 will be received in the space 28 which is present between the vertical inner surface of the angled profile 6 of the frame 5 and the side wall 27 of the pallet 26.
  • leg 7 of the upper centring member 1 is pivoted counter clockwise from the position shown in Fig. 1 to the position shown in Fig. 2 by means of the pneumatic cylinder 3.
  • the curved lower surface 29 of the cam 8 of the leg 7 will be positioned above the frame 5 so that when moving the pallet 26 into the frame 5 the latter can not be moved upwards or over a small distance only.
