Definitions

  • the present invention relates to a device for wetting trees with a funnel, through which the tree is pulled axially, wherein a net placed around the funnel is pulled off the funnel and the tree is wetted and with pliers arranged on a carriage which can be moved in the longitudinal direction, which covers the end of the tree.
  • Such devices are known from the prior art and are used in particular for the mechanical wetting of Christmas trees.
  • Christmas trees generally come in various graded size classes, for example in lengths of 1 m to 1.5 m, 1.5 m to 2 m, 2 m to 2.5 m.
  • a length class therefore includes all trees with a maximum length difference of 50 cm or 30 cm. For the sale, the trees have to be sorted by the manufacturer according to these length classes.
  • the object of the present invention is therefore to provide a device of the type mentioned at the outset, with which the tree can be marked not only in a networked manner but also at the same time by machine according to its belonging to the respective length class.
  • a device according to the invention with the characterizing features of the main claim solves this problem.
  • the device according to the invention has a length measuring device and a computer that is programmed so that it measures the measured length of a Assigns the marking color that corresponds to the respective length class.
  • a marking device is then set in motion via a controller, which then marks the tree in the appropriate color. This measuring and marking takes place in a very short time, practically in one step with the wetting of the tree.
  • a plurality of containers with different colors are preferably arranged on the longitudinally movable carriage, the pliers of which hold the tree end, each of which is connected via lines to a spray head arranged in the area of the pliers.
  • These lines from the respective paint containers to the spray heads are preferably closable via solenoid valves which are controlled by the control.
  • the tree length can be measured, for example, using a light scanner that detects the top of the tree as it passes.
  • the respective position of the driven slide can take place, for example, via an incremental displacement sensor arranged in the area of the drive of the slide, which signals a signal corresponding to the respective position of the slide to the control so that the computer can calculate the tree length.
  • FIGS. 1 to 3 The illustration shows a device for wetting, measuring and colored marking of Christmas trees with a machine frame 1, on which a carriage 14 can be moved in the longitudinal direction by means of a drive (not shown).
  • a toothed belt 26a which is guided over a deflection roller 21 and is connected to a support arm of the slide 14, is driven by a drive.
  • This support arm is received by a slot 25 in the machine frame and is guided there in the longitudinal direction when moving.
  • the device has a programmable logic controller which is accommodated in a switch box 22.
  • a funnel 10 is fixedly mounted on the machine frame 1, the axis of which is oriented in the longitudinal direction and through which the Christmas trees are pulled axially during the wetting process, as can be seen from FIGS. 1 to 3.
  • Pliers 12 that grip the stem end 13 of the Christmas tree.
  • Fig. 1 shows the position of the device before the tree is wetted.
  • the carriage 14 with the pliers 12 travels into the funnel 10 to grip the stem end 13 of the tree.
  • the net 11 for the tree is pulled over the funnel 10.
  • An angled arm 27 is also attached to the side of the machine frame, at the front end of which a light sensor 23 is attached in a housing, which is arranged somewhat in front of the funnel 10 above the tree in its path.
  • the carriage 14 now travels in the longitudinal direction to the other end of the machine frame, the tree grasping the net 11, pulling it off the funnel 10 and thus being wetted.
  • the controller 22 sends a signal to the controller 22 (see also FIG. 5), the Christmas tree is then measured and, depending on the affiliation to a certain size class (for example 2 m to 2.5 m ) the tree is marked with a color corresponding to this size class.
  • FIG. 4 The enlarged representation of the carriage 14 according to FIG. 4 shows that several paint containers 15 with different colors for the marking are arranged next to one another on the carriage. From these containers 15, lines 16 each lead to a number of spray heads 18 corresponding to the number of different colors for the marking, which are arranged at the height of the tree stem 13 in an axial extension behind the latter. Between the end of the tree stem and the spray heads 18 there is a plate 19 with a template-like, preferably circular opening 20, through which the paint from the spray head onto the cut surface of the stem end of the tree can be sprayed. Solenoid valves 17 are arranged in the connection path between the lines 16 leading to the spray heads 18 and the individual paint containers 15, which solenoid valves 17 can be controlled via the control 22.
  • the measuring and marking of the trees when wetting is carried out as follows (see FIG. 5).
  • a deflection roller 21 in the area of which an incremental displacement sensor is arranged.
  • This incremental displacement sensor gives a signal corresponding to the position of the slide 14 to the control 22.
  • the control 22 receives the second signal from the light sensor 23 when the tree tip 24 has passed through it. From the signal that corresponds to the starting position of the carriage 14 when it detects the tree stem and the signal that corresponds to the position of the carriage 14 when the tree tip 24 passes the light scanner 23, the computer that is part of the controller 22 can Calculate tree length. He assigns this tree length to a stored length class, e.g.
  • the controller 22 controls the solenoid valve 17 of the associated paint container 15 corresponding to the color of this length class.
  • the valve is opened and the associated spray head 18 marks the cut surface at the end of the tree handle. This measurement and color marking of the tree takes place in a fraction of a second.
  • the solenoid valve 17 is closed again and the control causes the pliers 12 to open so that the tree can be removed and then gives another command to the drive 26 so that the carriage 14 moves back to the starting position and the next tree is inserted can.
