Description

DETAILED DESCRIPTION OF THE INVENTION To date, small parts such as punched parts, lathe parts, etc. produced at a processing site - from there they have to be transported to another processing site or to an intermediate warehouse, where they are stored in bulkheads. Those that cannot be processed as During this operation, the individual crates are stacked on a truck, if possible, and transported by forklift or other means.

The wooden boxes will be transported one by one again to the new site.

With this manual operation method, the product price is high. because,
The labor itself is expensive, and it is almost impossible to allocate operators in a purposeful and rational manner.
This is because, in the case of machines that are operated during periods of time, workers must be assigned to perform expensive and disliked night work.
? +? f and a loading or unloading station, which can also be configured as a loading and unloading station, and serves to eliminate the aforementioned drawbacks associated with small parts. Small parts include all items that cannot be handled as bulk shipping charges in arbitrary quantities. This means not only compression-molded parts made of sintered material, but also all kinds of turned and punched parts as well as assembled parts, such as ball bearings.

The intermediate storage device according to the present invention is characterized in that the storage device is substantially formed by a vertical cylindrical container, and inside the container is a rotatable column having a number of trays arranged one above the other at equal intervals. is accommodated and is characterized in that the outer wall of the container is provided with a slit extending over its entire height for loading and unloading the tray.

Intermediate storage f: The station according to the invention for loading and/or unloading comprises: a vertically movable support device adapted to the bottom of the cylindrical container; means for rotating the rotatable column when in position; a control device for the lifting device for raising and lowering the support device in stages corresponding to the equal spacing of the pans; and in the case of a loading station; A swiveling entry slide for guiding small parts on a rotating tray towards the support; The entry slide is arranged in such a way that the slide bar protrudes from the slit in the outer wall of the container into the area above the dish and the entry slide bar is pivoted out of the area above the dish before the support device is raised or lowered. A pivoting mechanism of the rod is controlled, □ a deflection device for guiding the small parts on the rotating tray in the case of an unloading station towards and through the slit 1; The device is movable from the slit towards the column so as to intersect the radius line pointing towards the center of the slit, and the deflection device is moved out of the area between the ridges before the support device is raised or lowered. The displacement mechanism is controlled such that when the column is rotated for unloading, the deflection device r is in the area above the column rIllO.

Hereinafter, the present invention will be explained in detail based on the drawings. In this case, all combinations shown and/or described that are not known are considered inventions and are subject to protection.

The intermediate storage according to the invention, as best seen in FIG. 3, comprises a cylindrical vertical container 1. The container has an outer container wall 1a and a bottom 1b. Inside the container, the support column 2 is rotatably supported by at least one ball bearing 3.

This support 2 has a large number of mounting plates 4 arranged vertically at equal intervals.
It is equipped with This mounting plate is connected to the support column so as not to rotate relative to each other. The outer wall of the container has a vertical slit 1c, as can be seen in particular from FIG. The container bottom 1b is provided with a conical rim 1di so that it can be placed in its entirety precisely and easily on a support device (C) designated 5. The support device has a corresponding conical receiving rim for this purpose. In addition, the container bottom 1b is provided with a cutout 1C for the seven orcs 11 of the forklift 12.The support device itself is provided with a rotation mechanism, here a motor 6. It is connected via a transmission 7 to a clutch half 8 which cooperates with a correspondingly designed second clutch half 9 which is provided at the lower end of the rotatable column. , a motor can rotate the column when the intermediate storage is installed at the station.Furthermore, the support device is equipped with a lifting device, which in the illustrated embodiment is a lifting platform 1 known per se.
It is formed as 0. The fixed abutment 13 belonging to the station is provided with markings 14. This marking has the same spacing as the rotary plate 4 and, together with the sensor 15 mounted on the support and the control device housed in the support 13, constantly changes the plate spacing in response to the pulses of the adjustable time relay. Abutment 1, which is useful for raising and lowering the lifting device only
Above inside 3 is the small j! of conveyor belt 16! The j'J roller 15 is supported as follows. That is, the small parts 21 are supported in such a way that they can easily reach the rotary plate 4 from the conveyor belt 16 at the same height.

A sliding rod 17 is pivotally attached to the base 13. This entry groove rod can enter the area between the two mounting plates 4 provided above and below through the slit 1C by a drive device (not shown). This guides the small parts towards the column when the tray is rotating. In this case, a suitable control mechanism is programmed as follows.

That is, when the tray rotates for loading in the direction of arrow 18 and the conveyor belt moves in the direction of arrow 19, there is no slippage.
The rod is programmed to pivot into the area above the pan and the slide rod to pivot out of the area above the pan before the support device is raised or lowered. If the deflection device, which is equipped with a return spring and is described below, is designed so as to also serve to pivot the entry slot rod, it is also possible to omit the rotation device 6 for the entry slot rod only. good. This deflection device is indicated by arrow 18
It serves to guide small parts on the tray rotating in the opposite direction to the slit and to pass through the slit.

This deflection device essentially also consists of an arm 2o which can be slid from the edge of the sling 1c towards the column 2. In this case, this sliding direction intersects a radial line pointing towards the center of the slit. In this case, the control mechanism for the drive mechanism of this arm is formed as follows. That is, when the intermediate storage is rotated for unloading in the direction opposite to arrow 18 and the conveyor belt 16 is moved in the direction opposite to arrow 19, the deflection device moves slowly towards the column, and The deflection device is configured in such a way that it moves out of the region of the dishing force before the support device is raised or lowered. In this case, it is particularly advantageous if a conveyor belt', not shown, is provided on the slidable arm, and this conveyor belt conveys the parts placed on it towards the slit 1c.

When the intermediate storage is filled, i.e. when the intermediate storage is in a device serving as a loading station, the empty intermediate storage is placed in the uppermost position at the beginning of loading, as shown in FIG. , it is advantageous to form a control device.

The motor 6 rotates the tray in the direction of the arrow 18, and the small parts 2
When 1 is guided by the conveyor belt 16, is there a load of 17 sliding rods? It is pivoted onto the support 1 and 4, so that the small part 21 can be slid towards the column 2. Therefore, it is possible to carry out a full load of 1ft. After an adjustable time has elapsed, the conveyor belt 16 is stopped, the entry rod 17 is swiveled back to its original position, and the support device is lowered by the spacing of the pans.

A second plate is then similarly loaded. This operation is repeated until all dishes have been loaded, then all drives are switched off and, if necessary, an optical or non-refractive signal is emitted. The full intermediate storage bin is then transported by forklift 12 to another location, such as an intermediate warehouse or unloading station, and a new empty intermediate storage bin is installed.

At the unloading station, unloading takes place in the opposite manner as described above: First, the intermediate storage is rotated in the direction opposite to the arrow 18 and the conveyor belt 16 is driven in the direction opposite to the arrow 19. The deflection device 20 is slowly inserted so that, starting from the small parts at the outer edge, all the small parts reach the area of the slit 1c and from there to the conveyor A416. When the deflection device 20 reaches the column and the deflection device is rotated so that the small parts 21 are removed from the tray - this time can be determined by a time relay, the deflection device is is retracted to the position , and the support device is raised by 1, δ between the plates. The unloading process is then repeated for the second pan. When the entire intermediate reservoir is empty, all drives are stopped and, if necessary, a signal is issued, so that the empty reservoir can be replaced by a fully Tf-loaded reservoir.
