Carton changing device

The invention relates to a device for disposal From manufactured TelJen (e.g. injection molded parts) to production machines (e.g. injection molding machines) is used »and a fully automatic ongoing production / also via a longer period, such as B. over several layers or over the weekend allows.

In the known existing devices of this type, containers are horizontal / d. H. on conveyor belts, roundels, etc. provided and further promoted / whereby the EineatzmÖgiichkeiten these systems are limited due to the space required.

It is the object of the invention, from the point of view of the small footprint / parts, to include directly after their manufacture .

This object is achieved in the case of the invention by means of a device which is designed like a strand and in which several interchangeable Containers are provided and move up in the paternoster principle, 'solved'.

The invention is based on a schematic sketch (Figure t) and an embodiment variant shown in perspective (Figure 2) explained in more detail.

The device is designed like a tower, with a frame structure (1) being vertically erected in the shape of a cuboid Reveals the basic structure. Several sides of this frame construction (1) can be replaced by plate elements (2) made of sheet metal, Plastic or the like. However, at least one side must remain accessible for loading the device.

In two opposite side parts, conveyor chains (4) (toothed belts, belts, etc.) are accommodated in guide rails (3). These run synchronously over a shaft (S) and move over corresponding rollers (6) / so that they form a closed conveyor unit. Between these two side parts, which were previously equipped with the conveyor unit, are at equal intervals on the conveyor chains (4) (toothed belts, belts, etc.) on support arms (7), support bases (8) for receiving cardboard boxes (9), baskets ο * the like . movably attached?

This vertically oriented conveyor unit ia paternoster principle are, with a relatively small footprint, several holding snugs (9) for holding files (16) arranged one above the other .

The device is equipped with lockable rollers (10) or wheels that allow the entire structure to be driven or rotated enable.

The electrical control (11) of the device is connected to the parts-producing machine by means of a cable (M) . A 5-decade preselection counter (13), which is completely preprogrammed with the number of parts in a full carton in the case of single-use tools, subtracts with each product flow pulse of the connected machine. When "zero" arrives, another pulse from the preselection counter (13) sets the conveyor unit in motion by a three-phase electric motor (14) and thus moves all containers (9) one station further. This three-phase electric motor (14) is fed by the Hets via cable U5). The preset counter (13) now sets the number of parts again given * and subtracts the production pulses from the connected machine, etc.

As an alternative to the control (11) via the preset counter (13) a counting of the parts (16) also via light barrier or similar (contactless) or by scanning (contact) possible. This happens sensibly on or on the conveyor belt (17) or directly when the parts (16) fall into the container groove (9).

By counting the containers (9) at one of the stations of the The conveyor unit becomes, after all of the containers (9) accommodated in the device have passed through and the total capacity has been exhausted of the device, a switch-off pulse is given to the dividing machine.

The device is loaded with the produced parts (16) via an independently operating, commercially available conveyor belt (17) stationed between the parts producing machine and the device.

Apparatus according to claim 1 and 2, characterized in that the basic structure consists of a cuboid, vertical erected metal frame construction, with a base area of approx. 90 cm 120 cm and a height of approx. 250 cm. 4. Device according to one of claims 1 to 3, characterized, that several sides of the aforementioned frame construction (1) are covered by screwed-on plastic or sheet metal plates (2). 5. Device according to one of claims 1 to 4, characterized in that that two sides of the device are accessible for loading stay. 6. Device according to one of claims 1 to 5, characterized in that that in the two opposite, by plates ab-v covered, side parts guide rails (3) are housed in which conveyor chains (4) (toothed belts, belts, etc.) to run. 7. Apparatus according to claim 6,
characterized, that the conveyor chains (4) (toothed belts, belts, etc.) over a shaft (5) run synchronously and are deflected by rollers (6) so that a closed conveyor unit is created. 8. Device according to one of claims 1 to 7, characterized, that on the conveyor chains (4) (toothed belts, belts, etc.) are attached to movable support arms {7) supporting bases (8) for receiving containers (9) (boxes, baskets, etc.). • 1 «III KWV - 3 - 9. Device according to one of claims 1 to 4, characterized in that that sierarretbaren rollers (10) or wheels equipped is / that allow driving or twisting of the entire body. 10 «Device according to one of claims 1 to 9, characterized in that that on one of the closed side walls a switch box is attached, in which the electrical control (11) is located. This is connected to the part-producing machine by means of a cable (12) Machine connected. 11. Device according to claim 10 /
characterized, that the aforementioned electrical control of the device is equipped with a 5-decade preset counter (13), which is programmed with an entered number of parts, the work impulses of the connected production machine subtracted and at the zero position the conveyor unit is moved one station further and then automatically the subtraction process of the entered number of pieces to "zero" starts again from the beginning, etc. As an alternative to this, the device can also be characterized in this way be that the counting of the parts (16) via light cabinet or similar (contactless) or via scanning (contact) is possible, this being sensible on the conveyor belt (17) or directly when the parts (16) fall into the containers (9) happens. 12. Device according to one of claims 1 to 11, characterized, that the conveyor unit via the control (11) with a 380V three-phase electric motor with a power consumption of 5OW works.
