Definitions
- the invention relates to a device for carrying out check-like check weighings of filled packs, in particular coffee packs, which can be transported in a continuous row on a conveyor, a test pack being taken from the current transport flow and placed on a (control) balance.
- the checkweighing should be carried out as accurately as possible so that the actual filling weights come close to the target weight.
- precision scales with a tolerance range of + 0.1 g are used when carrying out the weight control.
- test packs are removed by hand from the transport flow of the packs and placed on the (precision) balance. The results measured are registered and processed in a suitable manner.
- the object of the invention is to simplify the processes in connection with carrying out checkweighing.
- the manual effort should be reduced or avoided.
- the implementation of checkweighing should be made independent of personal influence.
- the device according to the invention is characterized in that the test pack can be pushed off the conveyor and pushed onto a scale by a slide which can be moved back and forth transversely to the conveying direction of the packs.
- the process of removing individual test packs from the flow of the packs is accordingly mechanized according to the invention. This applies not only to the transfer of the test packs to the (precision) balance, but also to the return of the test packs according to the invention after weighing in the flow of the packs.
- the invention makes it possible to make the area of checkweighing independent of operator personnel and to automate it. As a result, it is also possible to determine the time or frequency of the checkweighings more precisely, either by determining time intervals which are controlled by suitable time measuring devices or by counting devices which trigger the checkweighings in accordance with the number of packs conveyed.
- the slide for the removal and return of the test packs is designed according to the invention in a special way, namely provided with holding jaws which rest on the side faces of the same when a test pack is taken over.
- the slide equipped with a U-holder is always in the starting position in the area of the row of continuously conveyed packings, in such a way that they are conveyed between the holding jaws located at a corresponding distance from one another.
- the holding jaws are moved against each other, whereby the test package in question is gripped and then conveyed out of the conveying stream (row of packages).
- test packs For the removal and return of the test packs from or into the row of packs, these are stopped beforehand, so that the test pack in question can be freely removed or returned.
- a package is fixed within the row at a distance from the slide, in particular by clamping, in such a way that the subsequent, accumulating packages are stopped.
- the pack in front can now be gripped in the manner according to the invention and transversely conveyed away. The same procedure is followed if the test pack is to be returned in a row.
- a particular invention can be seen in the measures for transferring the package to the scale and returning it.
- the packs are placed on an intermediate holder which is plate-shaped and extends in the starting position approximately at the level of the conveyor for the packs. After the test pack placed on the intermediate holder by the slide has been released, there is a downward movement and the test pack is thus handed over to the balance. During the weighing, the test pack left the intermediate holder, after which it was taken over again and fed to the intermediate holder.
- the balance or a balance cover is provided with support pins or support bolts pointing upwards, onto which the test pack is placed.
- the plate-shaped intermediate holder is provided with recesses (bores) through which the support pins pass while lifting off the test pack.
- the invention is particularly suitable in connection with the production of packs for food and beverages, especially for the packaging of roasted coffee, since a particularly precise weighing is important here.
- the exemplary embodiment shown relates to the treatment of essentially cuboid packs 10, in particular coffee packs. Coming from a packaging or filling machine, these are transported in a continuous row 11 on a conveyor 12. In the exemplary embodiment shown, the packs 10 are arranged within the row 11 with small distances from one another. Alternatively, the packs 10 can be conveyed in a sealed position within the row 11. A continuously rotating conveyor belt is preferably considered as the conveyor 12.
- the packs 10 arrive in the area of a weighing station 13.
- individual test packs 14 are taken out of the row 11 and fed to a scale 15 (precision scale).
- the weight of the test package 14 is determined on this by weighing.
- the test pack 14 is transported back into the conveying flow, that is to say into the row 11.
- test package 14 The transverse transport of the test package 14 to the balance 15 and back to the conveyor 12 takes place by means of a slide 16 which acts in both directions.
- a U-holder 20 for receiving a test pack 14 is attached in the present exemplary embodiment.
- This U-holder 20 is dimensioned such that its legs 21, 22 pointing downward extend on both sides of the packs 10 of the row 11.
- Pressure cylinder 17, piston rod 19 and U-holder 20 are mounted so that the latter is held above the row 11 of the packs 10. 1 and 2 show the initial position, in which the packs 10 are continuously conveyed between the legs 21 and 22 of the U-holder 20.
- test pack 14 For the transverse transport of a test pack 14, the U-holder is moved accordingly by retracting the piston rod 19. The test pack 14 is taken along in one as well as in the other conveying direction. The legs 21 and 22 rest on one of two opposite side surfaces 23, 24 of the test pack 14.
- the test pack 14 can be clamped on the slide, namely in the U-holder 20.
- 20 jaws 25, 26 are attached to the legs 20, 21 of the U-holder. These are designed as approximately spherical elevations which protrude inwards, namely to the test pack 14.
- the one jaw 25 is arranged in a fixed manner, while the other jaw 26 is movable against the side surface 24, namely by means of a pressure medium cylinder 27.
- the jaws 25, 26 are Holder 20 fixed.
- Special measures are carried out in the area of transporting the packs 10 for carrying out the conveying movements of the test pack 14.
- the series 11 is currently stopped, in the present case with the conveyor 12 still running.
- a package 10a of the row 11 following in the transport direction of the test package 14 is stopped on the conveyor 12, in the present case by clamping onto a fixed side guide 28 of the conveyor 12.
- a pressure medium cylinder 30 is attached in the area of an opposite side guide 29, the piston rod of which is equipped with a pressure jaw 31. This is moved against the facing side surface 23 of the package 10a. This in turn is clamped on the opposite side guide 28.
- the subsequent packs 10 run against this pack 10a and are thus fixed.
- test pack 14 lying in front of the pack 10a in the transport direction and the further packs 10 are meanwhile transported further by the conveyor 12.
- the test pack reaches the area of the slide 16, namely between the legs 21, 22 of the U-holder, it is held in place by the clamping jaws 25, 26 within the U-holder 20.
- the cross-conveying of the test package 14 can now take place with the slide 16.
- the lock in the area of the pack 10a is then lifted and the packs 10 or row 11 can be conveyed further.
- the jaws 25, 26 are opened so that the test package 14 is released from the slide 16.
- the test package 14 is again picked up by the slide 16 or the U-holder 20 and fixed in the manner described by the clamping jaws 25, 26.
- the test pack 14 is then returned to the conveyor 12 by a corresponding counter-movement of the slide 16.
- the transport is continued.
- the slide 16 or the U-holder 20 remains in the starting position according to FIGS. 1 and 2 until the next check weighing is triggered by appropriate control.
- the test pack 14 is placed on an intermediate holder 32 by the slide 16. This is plate-shaped with an upper-side bearing surface 33 for receiving the test pack 14.
- the intermediate holder is mounted above the balance 15 so that it can be moved up and down. A vertical guide for this is not shown in the drawings for reasons of simplification.
- a pressure medium cylinder 34 is used to carry out the up and down movements, the piston rod 35 of which is laterally connected to the intermediate holder 32.
- the intermediate holder 32 is in the starting position approximately at the level of the conveyor 12, so that, as in the present embodiment, an immediate transfer is possible.
- the bearing surface 33 expediently extends slightly below the transport plane of the conveyor 12, so that the test package 14 can be transferred without tilting. This is placed in a position exactly above the scale 15 on the intermediate holder 32 and, after being released by the slide 16, fed to the scale 15 by downward movement.
- the scale 15 is also designed in a special way for the automation of the processes described.
- Special holders in the form of support pins 37 projecting upwards are arranged on a balance cover 36, which is intended for receiving the goods to be weighed.
- four such support pins are attached to the balance cover 36 at equal distances from one another.
- the test package 14 is placed on the upper, free ends of the support pins 37 for carrying out the weighing.
- the intermediate holder 32 To transfer the test package 14 to the balance 15 through the intermediate holder 32, the latter is equipped with recesses in the form of bores 38. These are located in the vertical axis of the support pins 37, so that with a corresponding downward movement of the intermediate holder 32, the support pins 37 pass through the correspondingly dimensioned bores 38.
- test pack is taken over by the support pins 37 when the intermediate holder 32 continues to lower, and at the same time is lifted off the bearing surface 33.
- the test pack 13 rests freely on the support pins 37.
- the dimensions of the support pins 37 on the one hand and the bores 38 on the other hand and the movement amplitude of the intermediate holder 32 are coordinated so that in the lower end position of the intermediate holder 32 after transfer of the test pack 14 to the support pins 37 of the intermediate holder 32 without contact with the test pack 14, the Support pins 37 or the balance cover 36 is held. Weighing can therefore be done without influence.
- the balance cover 36 here consists of an upright cylinder piece 39 and a support plate 40 arranged thereon.
- the latter serves to receive the support pins 37.
- the arrangement of the latter is such that they lie predominantly within the circle described by the cylinder piece 39. This results in a statically perfect, accurate transmission of the load acting on the support pins 37 to the scale 15.
- the test package 14 is lifted from the support pins 37 by the upward movement of the intermediate holder 32 and conveyed back into the area of the slide 16 or the U-holder.
- the test pack 14 is received by the U-holder 20 in the manner described.
- the intermediate holder 32 is expediently fixed at a higher level such that the bearing surface 33 extends slightly above the level of the conveyor 12 in order to ensure that the test package 14 is returned without tilting.
- other, separate, in particular movable, transmission members can be arranged between the conveyor 12 and the intermediate holder 32 for transferring the test packs 14.
- Suitable control devices are assigned to the individual units of the device, e.g. Light barriers, microswitches etc., which control the sequence of movements in the sequence described by means of a corresponding relative arrangement.
