Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the disadvantage here is that a quick and precise bundling or wrapping of elongated things is not possible with this device.
  • Another disadvantage is that the centered bundling or wrapping of elongated things can only be done insufficiently by hand.
  • a high level of force is required for the actual bundling or wrapping process, since the adhesive tape must be carried out directly while overcoming the adhesive strength of the adhesive tape during the bundling or wrapping process.
  • the beginning of the tape must be manually applied to things to be wrapped. After the bundling or wrapping process, the adhesive tape must be cut off as well as the end of the adhesive tape must be pressed onto the elongated things.
  • wrapping with adhesive tape under constant pressure is hardly possible since a central position of the things to be wrapped is difficult to achieve.
  • the object of the invention was therefore to provide a device according to the preamble of claim 1 which does not have the aforementioned disadvantages, or to provide such a device which enables a fast and exact bundling or wrapping of elongated things.
  • the device according to the invention achieves a uniformly strong wrapping of the adhesive tape even with the eccentric position of elongated objects. This is achieved on the one hand if a loop of the adhesive tape is formed before the wrapping process, which of course must be dimensioned such that it is sufficient for such a wrapping process that the adhesive tape is not unwound directly from the roll of adhesive tape during the wrapping process.
  • the device for forming loops means that forces for unwinding the adhesive tape from the adhesive roll and for the wrapping process do not have to be applied all at once, but in succession. This is advantageous in both manual and motor operation. Because of the lower wrapping force to be applied as a result, it is only possible that a tape pressure device that moves within the winding wheel ensures a predeterminable, uniform pressure of the adhesive tape around elongated things.
  • the band pressure device is designed as two symmetrically opposing pressure parts, each of which is connected on the inside at one end parallel to the edge near the opening with a joint and taper in a V-shape and on the other End under mutual tension of springs.
  • the jaw-like, spring-loaded band pressure device is designed with two symmetrically opposite V-shaped band springs, each of which is connected on the inside at its bending edge parallel to the edge near the opening cut with a joint, the opposite leg of the band springs being V-shaped run towards and at the other end of the legs are under mutual spring tension. This ensures that the band springs have the same function as pressure parts, which can thus be saved.
  • a coaxial stop is provided on both sides of the winding wheel for axially fixing the items to be wrapped.
  • a precise axial position can be set by a stop that can be adjusted radially to the winding wheel.
  • the stop is advantageously designed with a switch for rotating the winding wheel.
  • An AND logic circuit of the two switches can provide that the rotation of the winding wheel can only be effected when both switches are actuated, which is particularly advantageous with regard to accident prevention measures.
  • a deflection wheel with a freewheel in the transport direction of the adhesive tape is provided, which is arranged between the adhesive tape holder and the winding wheel and thereby ensures loop formation that the adhesive tape holder is moved away from the deflecting wheel, the adhesive tape being pulled off the adhesive tape holder, preferably through a lifting cylinder.
  • the deflection wheel With its radial, uniformly rough surface, the deflection wheel forms enough contact on the one hand with the adhesive side of the adhesive tape to be able to remove the adhesive tape from the adhesive tape roll by means of the freewheel, and on the other hand to be able to easily remove the adhesive tape in the freewheel direction.
  • a further simplification of the wrapping process is provided in that a tape cutting device is arranged in front of the opening of the winding wheel, which consists of a stationary cutting knife and a movable anvil.
  • the anvil is designed to be pushable against the cutting knife by means of a lifting cylinder.
  • the stroke cylinder or the anvil can be controlled by a predeterminable time-delayed pulse from the switch of the stop in such a way that the adhesive tape length can be specified in proportion to the time delay.
  • a further advantageous embodiment of the invention is to be seen in the fact that a device is provided in the ready position for holding a start of the adhesive tape in the area in front of the opening of the winding wheel.
  • the device comprises a cylindrical wheel for supporting the non-adhesive side of the beginning of the adhesive tape, thereby to coiling thing one hand live page contact with the K of the adhesive tape gets, on the other hand well guided by the cylindrical wheel, the thing in a thing guide that connects the upper edge of the wheel with the area of the axis of the winding wheel, the thing guidance being provided on both sides of the wheel and the winding wheel.
  • a pressure guide with a band deflector which acts indirectly on the latter. This is a safe introduction of the thing in the winding head on the D ing arrangement possible.
  • the pressure guide In order to fix the beginning of the tape, the pressure guide has a narrow contact surface for the adhesive side of the tape for the purpose of holding.
  • a motor driven by compressed air has proven to be particularly suitable for driving the winding wheel.
  • An advantage here is the high initial torque, the small size and the lack of cooling problems.
  • the switch and the lifting cylinder can be driven pneumatically, since then the device can only be operated with compressed air.
  • the end of the tapered legs of the band springs is provided at least up to the end of the cable guide.
  • a toothed ring is arranged on both sides of the winding wheel so that the adhesive tape can be wrapped freely around the thing.
  • the adhesive tape can move between these two sprockets.
  • the outer end of the pressure guide is adjustable relative to the cylindrical wheel, for. B.
  • the necessary initial length of the tape can be specified in such a way that there is no danger that the adhesive sides can come into contact with one another.
  • the outer end of the pressure guide is moved down; vice versa for bigger things.
  • FIG. 1 shows the device 1 in a side view.
  • an adhesive tape holder 3 in the form of a winding mandrel 4 is arranged on the device 1.
  • the adhesive tape 5 runs over a plurality of wheels 6, 7, 8, 9 from the adhesive tape holder 3 to the cylindrical wheel 10, this wheel 10 serving as a support 11 on the non-adhesive side of the beginning of the adhesive tape 5.
  • a device 14 is arranged in the area in front of the opening 12 of the winding wheel 13 to keep the beginning of the adhesive tape 5 ready.
  • This device 14 essentially consists of the cylindrical wheel 10 and a pressure guide 15.
  • the pressure guide 15 has a narrow contact surface 16 for the adhesive side 17 in order to hold the tape 5.
  • a band deflector 18 is arranged on the pressure guide 15, which leads the band 5 centrally to the opening 12 of the winding wheel 13.
  • the winding wheel 13 essentially consists of a hollow cylindrical wheel, which has a segment-like opening 12 and on both sides of the winding wheel 13 a ring gear 19, 20 for a radial drive.
  • a tape pressing device 21 Inside of the winding wheel 13, a tape pressing device 21 is ordered, the two symmetrically opposed pressing members 22, 23 which are each parallel at one end for R and thoroughly the opening 12 on the inside with a hinge 24, 25 are connected and a V-shape to run and at the other Stand under mutual tension of springs 26, 27.
  • the winding wheel 13 is brought into a standby position with a freely accessible opening 12 after each winding process.
  • This position is shown in FIG. 1.
  • the device 28 essentially consists of a motor 29 driven by compressed air, which drives a gearwheel 30.
  • This gear 30 is designed so that it only performs one revolution per winding process.
  • An intermediate gear 31 is designed so that with one revolution of the Gear 30 the winding wheel 13 executes 4 revolutions, for example.
  • a lifting cylinder 32 releases the gearwheel 30 from its latching and is started together with the motor 29.
  • the motor 29 is switched off via a shut-off valve 34 via a lever 33.
  • the impulse generated during this stopping process on the locking hook 35 and the detent 36 is transmitted via the rod 37 to an oil shock absorber 38 and is collected there.
  • a backstop 39 catches the counter impulse.
  • a band cutting device 42 is arranged, which consists of a cutting knife 43 and an anvil 44.
  • the anvil 44 is driven by a lifting cylinder 45 against the cutting knife 43, the fork-shaped end piece of the anvil 44 enclosing the cutting knife 43 and thus cutting the adhesive tape 5.
  • the lifting cylinder 45 can be controlled by an adjustable control valve 46 by means of a predeterminable time-delayed pulse. The time delay can be set on the adjusting wheel 47.
  • the adhesive tape holder 3 is provided with a device 48 for movements relative to the deflection wheel 6.
  • the device 48 consists of a lifting cylinder 49 which, with its piston, performs relative movements towards the deflection wheel 6 and, for the purpose of greater stability, the adhesive tape holder 3 is assigned a rotatable guide lever 50.
  • the lifting cylinder 49 increases the distance between the adhesive tape holder 3 and the wheel 6 by a part such as that for the length of the adhesive tape 5 is necessary for a wrapping process.
  • This loop formation is made possible by the fact that the wheel 6 has a freewheel in a clockwise direction, so that when the adhesive tape holder 3 is moved away from the wheel 6 it locks and the tape 5 is held by contact with the adhesive side 17. To set the friction, the adhesive tape holder 3 is set up with an adjusting screw 53.
  • a compressed air connection 51 for the lifting cylinder and the compressed air driven motor 29 is arranged at the rear of the device 1.
  • a mounting receptacle 52 is provided on the lower, rear part of the device 1 for optional mounting on a table or on an adjustable tripod.
  • FIG. 2 A simplified side view of the front side of the device 1 is shown in FIG. 2. The position and dimensioning of the device 48, the winding wheel 13 and the motor 29 can be seen from this.
  • an adjustable stop 54, 55 is provided, which fixes the things to be wrapped approximately centrally in the winding wheel 13.
  • the sectional view of the winding wheel 13 corresponds to the section A-A according to FIG. 1.
  • the stop 55 is here provided as a pneumatic switch 56, each with a compressed air inlet and outlet 57, 58. If switches 56 are provided on both sides of the winding wheel 13, these switches 56 can be logically connected to one another in such a way that things 59 to be wrapped can only be wrapped by the winding wheel 13 if the thing 59 to be wrapped is placed approximately centrally in the winding wheel 13.
  • the motor 29 is started via the switch 56 via the compressed air inlet / outlet line 57, 58.
  • the wheel 9 is provided with a freewheel so that the band 5 cannot retract in the direction of the wheel 6 or the adhesive tape holder 3. To adjust the friction on the wheel 9, this is provided with a screw 60.
  • the pressure guide 15 lying above it is rotatably mounted at the pivot point 62.
  • the upper part of the holder 61 serves as a guide 63 of a thing 59.
  • the counterpart to this is the lower side of the pressure guide 15.
  • the adhesive tape 5 is wrapped with its adhesive side 17 with about a 1/4 to a 1/2 turn.
  • the plate 64 is preferably formed from a low-friction material or plastic.
  • FIG. 4 shows the device 1 according to FIG. 3 in a view from the front.
  • the band pressure device 21 has two symmetrically opposite V- shaped band springs 65, 66, each of which is connected on the inside at its bending edge 67, 68 parallel to the edge near the opening 12 with a joint 24, 25.
  • the opposite legs 69, 70 of the band springs 65, 66 run in a V-shape from the joints 24, 25 and are at the points of contact of the legs 69, 70 under mutual spring tension. This saves a separate spring 26, 27 (Fig. 1).
  • D ing 59 is in a fixed position, e.g. B. by holding with hands, the thing 59 rests against a stop 54, 55, not shown.
  • the band is cut off by actuating the lifting cylinder 45 by means of the band cutting device 42 during the winding process.
  • the band length around thing 59 is determined by the size of the time delay which can be set by means of an adjusting wheel 47 on the control valve 46.
  • the locking hook 35 engages with its catch 36 on the disk of the gear 30 and thus ends the winding process, which here z. B. consists of 4 revolutions.
  • the tape length to be wrapped must be dimensioned such that the specified tape length is completely wrapped around thing 59 after the winding process has ended.
  • the wheel 9 is provided with a freewheel which prevents this or prevents undesirable loop formation between the wheel 9 and the wheel 7. This ensures that the beginning of the tape comes to rest on the support 11 with the intended length of the tape 5.
  • the front end of the pressure guide 15 can be relative to the cylindrical wheel 10 as a function of the diameter of the thing 59 + to be wrapped, the device 72 being fixedly connected to the pressure guide 15, but also springing with the pressure guide 15.
