Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an intermediate storage device for storing and transporting small parts.

[Conventional technology]

To date, small parts, such as stamped parts, lathed parts, which are processed in a processing station and are galvanized or heat treated after production - from there they have to be transported to other processing stations or to intermediate warehouses and are then sent in bulk. Materials that cannot be processed as bulk materials are mostly hand-packed into crates and, after being stored for a period of time in an intermediate warehouse, or directly transported to other processing stations without being stored in an intermediate warehouse, where they are It is again fed by hand to other processing or processing equipment. During this manual handling operation, individual crates are stacked on pallets, if possible, and transported by forklift or other vehicle. At another station, the crates are transported one by one again. This manual handling method leads to increased product prices. This is because the labor itself is expensive, and it is almost impossible to allocate operators in a purposeful or rational manner, and in the case of machines that are operated all day long,
This is because workers must be assigned to work at night, which is expensive and disliked.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

The intermediate storage according to the invention comprises a cylindrical vertical container 1, as shown in particular in FIG. This container includes a container outer peripheral wall 1a and a bottom 1b.
In the container, the column 2 has at least one ball bearing 3
It is rotatably supported by. This pillar 2
is equipped with a large number of trays 4 arranged vertically at equal intervals. This mounting plate 4 is connected to the support column 2 so as not to rotate relative to the support column 2. Platter 4
is formed into a circle corresponding to the shape of the cylindrical container 1, and is fixed to the support column 2 at its center. As can be seen in particular from FIG. 2, the container outer peripheral wall 1a has one vertical slit 1c extending from its upper end to its lower end. The container bottom 1b is provided with a conical edge 1d so that it can be placed exactly and easily on a support device generally designated 5. For this purpose, the support device 5 is provided with a corresponding conical receiving edge portion 5a. Furthermore, the container bottom 1b is provided with a notch 1e into which the fork 11 of the forklift 12 is inserted. The support device 5 itself is equipped with rotational drive means, ie a motor 6. This motor is connected via a transmission 7 to a clutch drive 8 . This clutch drive side cooperates with a clutch drive side 9 correspondingly formed and mounted on the lower end of the rotatable column 2, so that
The motor 6 allows the support 2 of the intermediate reservoir to be rotated when the intermediate reservoir is installed in the station. The support device 5 furthermore comprises a lifting device. In the embodiment shown, this lifting device is designed as a lifting platform 10, which is known per se. Abutment 13 fixedly arranged on the station
is equipped with a scale 14 carved in the vertical direction.
A large number of scales are provided at the same intervals as the mounting plate 4, and a sensor 15a provided on the support device 5
(See Figure 1). This sensor, together with a control device housed in the base 13, serves to raise and lower the platform 10 by the distance of the tray 4 in each case by means of pulses from an adjustable time relay. A driving roller of the conveyor belt 16 is supported above the support base 13 as follows. That is, the small parts 21 are supported so that they can easily reach the tray 4 located at the same height from the conveyor belt 16.

The support base 13 further includes a guide rocking rod 17 for loading.
is pivotably mounted. This guide rocking rod is swung by a swinging mechanism (not shown) and can enter between the two plates 4 through the slit 1c. As a result, when the tray is rotating, the small parts placed on the tray 4 from the conveyor belt 16 are rotated together with the tray and moved by the guide rocking rod 17.
is deflected radially inwardly along this guide rocker and guided towards the column 2. In this case, a suitable rocking mechanism for the guide rocker 17 is programmed as follows. That is, when the tray 4 is rotated for loading in the direction of the arrow 18 and the conveyor belt 16 is moving in the direction of the arrow 19, the rocking mechanism causes the guide rocker to swing between the trays 4. , and is program-controlled so that the guide rocking rod 17 swings out from between the trays 4 through the slit 1c before the support device 5 is raised or lowered. If the guide rocker 17 is provided with a return spring and the unloading deflection device 20 described below is designed in such a way that it also serves to rock the guide rocker, a rocking mechanism for the guide rocker is provided. may be omitted. This deflection device 20 moves the small parts on the tray rotating in the direction opposite to the arrow 18 into the slit 1.
c and through the slit 1c towards the conveyor belt 16. This deflection device 20 essentially consists of an arm that can be slid from the edge of the slot 1c towards the column 2. In this case, this direction of oscillation intersects a radial line extending from the column 2 towards the center of the slot 1c. At this time, the swinging mechanism of this arm is controlled as follows. That is, the intermediate storage is rotated in the direction opposite to the arrow 18 for unloading, and the conveyor belt 1
6 moves in the direction opposite to the arrow 19, the deflection device 20 slides slowly towards the column 2, and before the lifting and lowering of the support device 5, the deflection device 20 moves out of the container 1. controlled. When the deflection device 20 is slowly slid toward the support column 2 for unloading, the small parts on the tray 4 rotating in the direction opposite to the arrow 18 hit the deflection device 20 and pass through the slit 1c. You will be guided towards conveyor belt 1.
Reach 6. In this case, it is particularly advantageous if the slidable arm is provided with a conveyor belt (not shown), which conveys the parts placed on it towards the slot 1c. After the unloading of the small parts has been completed, the deflection device 20 is slid outwards out of the container 1. Thereby, the deflection device 20 does not get in the way when the support device 5 is raised and lowered in order to unload the next tray 4.

When loading the intermediate storage with small parts, i.e. when the intermediate storage is in a device acting as a loading station, at the beginning of loading the empty intermediate storage is placed in the uppermost position as shown in Figure 3. It is advantageous to form the control device in such a way that it is placed in the same position. When the motor 6 rotates the tray 4 in the direction of the arrow 18 and the small parts 21 are guided by the conveyor belt 16, the guide rocker 17 is swung onto the tray 4 to be loaded. . Thereby, the small parts 21 come into contact with the guide rocking rod 17 and slide toward the column 2, so that the tray 4 can be loaded. After the loading of the tray 4 has been completed, i.e. after an adjustable time has elapsed, the conveyor belt 16 is stopped and the guide rocker 17 is swung back to its original position, i.e. to the outside of the container 1; The support device 5 is then lowered by the distance of the tray 4. Thereafter, the second tray 4 is similarly loaded. This operation is repeated until all the trays have been loaded, and then all drives are switched off and, if necessary, a light signal or the like is emitted. The full intermediate storage bin is then transported to another location by forklift 12, and a new empty intermediate storage bin is installed at the loading station.

At the unloading station, unloading takes place in the opposite manner.

First, the intermediate storage is rotated in the direction opposite to arrow 18 and the conveyor belt 16 is driven in the direction opposite to arrow 19. The deflection device 20 is loosely inserted between the trays 4 through the slit 1c, so that starting from the small parts on the outer edge of the tray 4, all the small parts are slit along the deflection device 20. 1c and from there reaches the conveyor belt 16. When the deflection device 20 is inserted up to the column 2 and the tray is rotated in such a way that all small parts 21 are carried away from the tray 4 - this time can be predetermined by a time relay, the deflection occurs. The device 20 is retracted into its original position, ie outside the container 1, and the support device 5 is lifted by the spacing of the tray 4. The unloading process is then repeated for the second pan. When the entire intermediate storage is empty, all drives are stopped and, if necessary, a signal is issued so that the empty intermediate storage can be replaced by a fully loaded intermediate storage.
