DE2852551A1 - Lamp filaments and other components sorting machine feed mechanism - has angularly adjustable tilting and vibrating arm for component container - Google Patents

Abstract

The mechanism feeds a vibratory sorting machine with small components, such as lamp filaments, electronic components, coil springs etc, stored in containers in random quantities, which have to be fed in the machine metered quantities. It has a vibrating arm, accommodating one or more component containers, whose inclination to the horizontal is adjusted dependent on the quantity and type of the components contained in the hopper. The vibration mechanism preferably consists of a stepping motor, coupled to the arm by a shaft, so as to adjust it into various angular positions and to vibrate it. On the arm discharge side may be provided a chute. The machine may have a signal generator acting as component detector and controlling the stepping motor.

Description

The invention relates to a device accordingly

the preamble of claim 1.

Small parts, such as filaments for incandescent lamps, are common Supplied in containers by the manufacturer in an unspecified number. Around to avoid a jam in the sorter that affects the coils of a processing machine feeds individually, one person checks the spirals in the sorter. Before the spirals in the sorter are used up, more spirals are added shaken from a container into the sorter.

This process has a number of disadvantages. The Wendem can become entangled both in the container and when shaking out of the container, so that they are damaged or the sorter cannot process them. To this To avoid this, there may be a fan in the sorter through which the newly entered Spirals are blown into a glass flask and thereby detached from one another. Similar Difficulties can also arise with other small parts, such as coil springs or also electronic components with relatively long connecting wires arise.

The invention is based on the object of the task of the initially to automate said device.

This object is achieved according to the invention by the in the characterizing Part Aes claim 1 specified features. Appropriate embodiments of the invention result from the subclaims.

This training allows the small parts located in a container be dispensed in precisely dosed quantities. The inclination of the seesaw in relation to the Horizontal will depend on the amount of small parts contained and their Art set. This type of delivery of the small parts to the sorter allows even a separation of the small parts can be achieved, so that a jam in the sorter can be avoided with certainty. Due to the shaking process, it is possible to reduce the Detaching small parts in the container from one another and causing damage to be avoided when handing over to the sorter.

The vibrator can be, for example, a stepper motor, its shaft is connected to the rocker. The stepper motor adjusts the rocker to the required position Inclined position and in this position shakes the rocker and thus the one on it Container. The shaking process can be controlled by appropriate control of the stepper motor can be achieved, with its shaft small pendulum movements around a certain, the required inclination of the rocker executes the corresponding position.

The stepper motor is controlled by a signal generator that is connected to the Sorter-cooperates. The signal transmitter signals the stepper motor if none Small parts are more-available. The sorter works in such a way that there are no gaps between the end of a given quantity and the beginning of the next quantity of small parts occurs.

The loading of the rocker with containers can take place automatically. For this purpose, the containers can be stacked vertically one above the other in a magazine. The bottom one Container is removed from the Magazine pushed onto the rocker and, after emptying, down through a slide submitted. To do this, the rocker is swiveled down and the one on it empty containers removed using an ejector.

The invention is explained below with reference to FIGS. 1 and 2, for example explained. It shows: FIG. 1 a side view of the device and FIG. 2 a At sight.

The loading device has a magazine 11 in which vertically one above the other Coils are stored for containers containing incandescent lamps. The magazine 11 is open a guide plate 14 is arranged on which a slide 13 by means of a lower the guide plate 14 arranged printing cylinder 15 is displaceable.

By means of the slide 13, the lowermost container 12 can be in the magazine 11 can be pushed onto a horizontally arranged rocker 16. In Figure 1 are except the horizontal position shows three more inclined positions of the rocker.

The rocker 16 consists of a plate, on the top of which there are two Guide strips 18 are located. On one of the guide rails is through spring elements 19 a terminal block 17 is attached so that the container located on the rocker 16 is being held. The terminal block 17 is interchangeable in order to adapt to different to allow wide container 12.

The rocker 16 is connected to a shaft 24 which is mounted in bearings 23 and connected to the output shaft of a stepping motor 21 through a clutch 22 is.

The rocker can be moved out of the horizontal position by means of the stepper motor be pivoted to an inclined position.

The inclination of the location depends on the amount and type of in the container located parts. The output shaft of the stepper motor leads in the selected position 21 and thus the drive shaft 24 of the rocker small pendulum movements, so that the rocker and the container on it is subjected to a shaking movement. This shaking movement removes a certain number of parts from the container. The shaking movement can be adjusted so that the parts separate the container leaving. After a certain amount has been removed, the rocker can move into a position with be swiveled at a greater incline in order to dispense more parts from the container.

From the rocker 16, the parts fall into a slide 26 and from this in a sorter 32, which is cup-shaped and in which the parts on the Run up the inner wall in a spiral. The sorter works with a signal transmitter 33, which determines when there are no more unsorted parts in the sorter. The signal transmitter 33 can, if the small parts are filaments for incandescent lamps acts, for example, be a color mark button, which the different reflection evaluates between the sorter and the coils and transmits it to the stepping motor 21 emits a corresponding signal, so that further parts are removed from the one on the rocker Container are dispensed. The signal generator can optionally be equipped with a delay element work together, so only after a certain residual amount of parts has been used up Another discharge from the container takes place in the sorter.

As soon as a container 12 is emptied, the rocker 16 is shown in the lower layer pivoted to remove the container. For this purpose there is 16 in the rocker an opening 20 is provided into which an ejector 28 engages and the one located on it Container removed. The ejector 28 can have a spring-loaded pin on the top (not shown) to facilitate the ejection process. Falls from the seesaw the empty container in a chute 29 and from this in an opening 31, the is formed in the base plate 27 of the device. To prevent a If the container reaches the base plate 27, a baffle plate 30 is at the opening 31 arranged.

The slide 13 that pulls the individual containers 12 out of the magazine 11 pushes on the rocker 16 is U-shaped. Located below the magazine 11 a spring-loaded pin (not shown), which by means of a lever and a pressure cylinder is adjustable to reach through between the two legs of the slide 13, as soon as this pushes a container out of the magazine.

The pin engages the underside of the next container and resiliently supports the stacked containers. By actuating the pressure cylinder can the container after the slide 13 is returned to its original position has been lowered onto the guide plate 14. This prevents that the container impact on the plate 14 and thereby those located therein Parts are damaged.
