Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for sorting package strips punched from a package strip filled with tablets or the like, wherein the punched package strips are conveyed using a delivery mechanism. Concerning the type of delivery to the belt.

Known delivery mechanism (West German Patent Application Publication No.
No. 1,756,245), the packaging strip is transferred from a delivery machine to a receiving machine by means of a rotating plate which is provided with corresponding recesses for the packaging strip. A stationary plate is placed below the rotating plate. The stationary plate also has a recess in the area of the conveyor belt for receiving the package strip and transferring it to the conveyor belt of the machine, which recess is closed by a flap or the like. Furthermore, the stationary plate has a recess in the region in front of the conveyor belt, which is also closed by a flap. When transferring a correctly filled packaging strip, the flap remains closed, whereas when transferring an incorrectly filled packaging strip (defective packaging strip), the flap remains closed. A flap located in the front area is opened and the defective packaging strip is removed. However, in this case there are often problems with the delivery of the packaging strip. The difficulties are mainly due to the fact that the packaging strip is left to its own free movement almost throughout the entire delivery journey and is not guided forcibly. Furthermore, there are difficulties in opening and closing the flaps, for example when the packaging strips become wedged, so that subsequent packaging strips can no longer be delivered regularly.

Furthermore, another means of sorting packaging strips is known from DE 195 5 359 A1. By this means, defective packaging strips are removed from the conveyor belt by an air stream. In this case, the air stream is arranged in such a way that correctly filled packaging strips are fed forward on the conveyor belt, while defective packaging strips are blown off the conveyor belt. However, all defective packaging strips, i.e. 1
It is virtually impossible to control the air flow to actually blow off a strip of packaging that is missing only one tablet. Air stream sorting operations therefore cannot ensure that only completely filled package strips remain on the conveyor belt.

An object of the present invention is to eliminate the drawbacks of the known technology, and in order to solve this problem, the present invention has a structure in which the delivery mechanism is constructed as a suction mechanism for sucking the packaging strip, and the suction mechanism is arranged on an arm. The machine is supported for oscillating movement about a substantially horizontal axis and is connected to a vacuum pump via a vacuum conduit, and a sorting mechanism cooperating with a suction mechanism separates the packaged product from the deep-drawn part of the packaged product. A detection mechanism for detecting whether the recess is filled with tablets or similar items, a memory device for storing pulses indicating defective packaging or a memory device for storing pulses indicating good packaging from the detection mechanism, and a vacuum conduit. an electromagnetic on-off valve that closes the vacuum conduit based on a signal from a memory device that stores a pulse indicating a defective package or opens the vacuum conduit based on a signal from a memory device that stores a pulse indicating a good package; An approximately vertical sorting channel for defective packaging strips is provided in the transfer section of the suction mechanism.

The advantage of the invention is that the sorting device is very simply constructed and that the sorting out of all defective packaging strips is reliably guaranteed during the forced transfer of the packaging strip from the puncher to the conveyor belt. be.

Next, embodiments of the present invention will be described using the drawings.

As shown in the drawing, a punching machine 2 punches out a packaged product strip 3 from a packaged product strip 1, and a suction mechanism is installed in which the packaged product strip 3 can swing (swivel) about a substantially horizontal axis. 4 to the conveyor belt 5. Below the suction mechanism 4 and in front of the conveyor belt 5, a sorting channel 6 for defective packaging strips 3' is arranged. Adsorption mechanism 4
is connected to a vacuum pump 8 via a vacuum conduit 7. An electromagnetic on-off valve 9 is arranged within the vacuum conduit 7. The electromagnetic on-off valve 9 is controlled by a known storage device (not shown) in which conditions for selecting defective packaging strips or screening conditions for good packaging strips are stored. The storage device storing the selection conditions for defective packaging strips or the storage device storing the selection conditions for good packaging strips is a detection mechanism (not shown) for detecting the packaging strip 1.
to indicate a defective package if there is no tablet or similar in the deep-drawn recess of the packaging strip, or if there is no tablet or similar in the deep-drawn recess of the packaging strip. If it is, you will receive a pulse indicating a good package. When the packaged product strip 1 has multiple rows of packaged product strips 3 arranged in parallel with each other, a plurality of suction mechanisms 4 corresponding to the number of packaged product strips 3 are arranged in parallel to each other. The electromagnetic on-off valves 9 are arranged in parallel corresponding to the
It is connected to the vacuum pump 8 via. If the storage device is adapted to receive a pulse indicating a defective package from the detection mechanism, when a defective packaging strip 3' of a defective package arrives in the punching machine 2, the storage device will cause the electromagnetic opening/closing to occur. The valve 9 is closed and the vacuum line 7 is shut off, so that the rejected packaging strip 3' is not picked up by the suction mechanism 4 and falls into the sorting channel 6. If the storage device is configured to receive a pulse indicating good packaging from the detection mechanism, when a packaging strip 3 with a good packaging arrives in the punching machine 2, the storage device will activate the electromagnetic on-off valve 9. is opened and the vacuum conduit 7 is communicated with the vacuum pump 8, so that the packaging strip 3 is attracted by the suction mechanism 4 and is reliably transferred to the conveyor belt.

Claims (1)

[Claims] 1. A device for sorting package strips punched from a package strip filled with tablets or similar products, in which the punched package strips are transferred to a conveyor belt using a transfer mechanism. The mechanism is configured as a suction mechanism 4 for suctioning the package strip 3, and the suction mechanism 4 is supported as an arm so as to be able to swing around a substantially horizontal axis, and is connected to a vacuum pump 8 via a vacuum conduit 7. A sorting mechanism that cooperates with the suction mechanism 4 separates the packaged product strip 1 from a detection mechanism that detects whether the deep-drawn recesses of the packaged product strip are filled with tablets or similar materials. vacuum conduit 7 based on signals from a memory device storing pulses indicating defective packaging or a memory device storing pulses indicating good packaging; and a memory device disposed within vacuum conduit 7 storing pulses indicating defective packaging. It consists of an electromagnetic opening/closing valve 9 which opens the vacuum conduit 7 based on a signal from a memory device that stores a pulse indicating a good package or closes a defective package strip 3' in a section where it is delivered to the suction mechanism 4.
