'I'm bored. This parts supply device has a parts feeder constituting a parts supply section, and 1 part is supplied from the parts feeder.
BACKGROUND ART Devices in which one or more types of parts are automatically stored in a parts storage section formed in a main body of an assembly are known in the past.

Normally, parts are not supplied directly from the parts feeder into the main body of the assembly due to constraints on the installation location, difficulty in aligning the parts feeder and the parts storage area, etc. The components are stored in each component storage section via a carry-in member. Conventionally, this carrying-in member is one in which all the parts from the parts feeder are separated one by one, and each part is transported separately to each parts storage part, and the parts are stored in each parts storage part. was used.

However, when the parts are taken out individually from the parts feeder and stored in the parts storage section in this way, the work of storing the parts becomes troublesome and the time required for this work becomes extremely long.

Therefore, in order to carry out the parts storage work completely continuously, a head for carrying out parts that can be connected to each parts storage part in the main body of the assembly is provided, and a completely flexible tube is connected between this head and the parts feeder. There is also known a device in which the parts are connected to each other by a tube, and parts are supplied from a metal part feeder to the head via this tube.

[Problem that the invention seeks to solve]

By the way, as mentioned above, is it possible to supply parts from a parts feeder using a tube? What should I do? ・Tubes with different dimensions depending on the shape of the parts to be supplied? This not only complicates the equipment configuration, but also increases the size of the equipment due to the installation of the tubes.Furthermore, the tubes must be completely replaced depending on the type of parts attached to the main body. First, there was a drawback that this tube conversion work was extremely troublesome.

The present invention has been made in view of the above points, and has a simple structure that allows each component in the main body of an assembly to be easily and quickly transferred from the parts supply section to the main body of the assembly, regardless of the type of parts supplied to the main body of one assembly. It is an object of the present invention to provide a complete parts supply device capable of supplying parts to a storage section.

[Means to solve all problems]

In order to achieve all of the above-mentioned objects, the parts supply device according to the present invention has an inlet for parts to be supplied from one or more parts supply units formed on one side, and a main body of the parts to be carried in on the other side. (1) a magazine-like moving chute which forms an outlet for carrying out a plurality of parts and stores a plurality of parts in an aligned state; By connecting this magazine-like moving chute with a transverse feed mechanism that moves in the orthogonal direction, the magazine-like moving chute can be moved to a parts loading position where its loading opening is connected to the parts supply section;
The feature is that the ejection port is displaced between the parts ejection position and the parts ejection position which are sequentially connected to the parts storage section of the main body.

[Effect]

In order to supply the parts to the main body of the entire assembly using the parts supplying device configured as described above, first, the vertical feeding mechanism and the horizontal feeding mechanism are appropriately driven to move the magazine-like moving chute. ,
The component is moved to a component loading position where the loading port is connected to the component supply section, and in this state, the component is loaded from the component supply section to the magazine-like moving chute. When a predetermined number of parts have been supplied to the magazine-like moving chute, the supply of one part is stopped, and the vertical feeding mechanism and the 9 horizontal feeding mechanisms are all driven again, and the moving chute is completely moved to the parts storage area of the main body of the outlet. The parts are moved to the parts loading position connected to the parts storage section where all the parts are to be stored. After storing this component in the component storage section, the cross-feeding mechanism is activated to move the moving chute until its outlet connects to the next component storage section. The parts are supplied to the assembly, and this operation is sequentially repeated to supply the parts to the assembly.

Furthermore, when this component supply is completed, by fully operating the vertical feed mechanism and the horizontal feed mechanism, the moving chute is returned to the component loading position to complete the supply of components, and the components are supplied to the next assembly to be transported. It will be done.

In addition, if the parts supplied to the parts storage parts in the main body part 5 are different in each parts storage part, a number of parts supply parts according to the types of parts to be supplied are provided, and each of these parts supply parts has a different type. Store all parts. Then, the magazine-like moving chute is sequentially connected to each component supply section in an order corresponding to the order of storage in the all-components storage section, and takes out the required number of components from each component supply section. In this way, the magazine-like movable chute 1 loaded with each component - its discharge port is sequentially connected to each component storage section of the main body, and these different types of components t
Each can be stored in a predetermined component storage section.

This embodiment is constructed as described above, and its operation will now be described with reference to FIGS. 5 to 7.

First, the ball screw device 6 as a horizontal feed mechanism and the cylinder 5 as a vertical feed mechanism are driven to move the movable chute 4 to the head whose inlet 4a constitutes the parts feeder 3, as shown by the dashed line in FIG. It is placed at a parts loading position connected to the head part 3a, and receives a predetermined number of parts P through the head part 3at.

Here, in this embodiment 9J, the parts Pffi are installed in eight parts storage parts excluding two parts storage parts 23 and 27 among the ten parts storage parts 21 to 210. Move chute 4 to 8 parts P
k can be accommodated. However, it goes without saying that the number of parts accommodated in the movable chute 4 may be larger than this.

As mentioned above, when the transport of the parts to the movable chute 4 is completed, the cylinder 5 is contracted and moved toward the arrow A in the figure.
The movable chute 4 is moved in the direction shown by the solid line to the position shown by the solid line in the whole figure, and the ejection port 4k1 of the movable chute is positioned approximately at the same level as the surface of the assembly main body 10 on the component storage side.

Components are stored in this new assembly main body 1 by the horizontal movement of the movable chute 4 by the ball screw device 6, and by repeating this sequentially, the parts are automatically stored in the assembly main body 1. be able to.

Here, not only the same number of parts are stored at the same position of the assembly main body that is transported to the position where the parts are to be stored sequentially, but also the position where the parts should be stored for each assembly main body. Even if the parts are different, by using this magazine-like moving chute, the parts can be stored smoothly and quickly. In other words, irrespective of whether or not all the parts that are traversed at the parts delivery position of the movable chute should be stored, the shutter in the separation mechanism part is positioned each time it faces each parts storage section, and the shutter in the separation mechanism section is only at the position where the parts are to be stored. You can choose where to store parts by opening the chute to supply parts, or by skipping parts storage areas where no parts are installed and moving the chute based on a preset program. can be done.

As mentioned above, the main body of the assembly having a large number of parts storage parts is sequentially transported, and all parts can be quickly and reliably automatically supplied to any one of these parts storage parts. from.

The component supply device of the present invention can be particularly suitably used, for example, for storing a tumbler in the cylinder body of a cylinder lock.

Furthermore, the parts supply device of the present invention can be configured to supply all parts of multiple types to the main body of the assembly. In this case, a number of parts feeders according to the types of parts are arranged in parallel, and the parts feeder is moved like a magazine. The chute may be sequentially connected to these parts feeders, and each part may be stored in the magazine-like movable chute in a predetermined order in an aligned state, and each of these parts may be stored in a predetermined parts storage section. In this case, by controlling the order in which the movable chute is connected to each parts feeder or to each parts storage section, it is possible to reliably store a predetermined component in a predetermined component storage section.

The vertical feed mechanism and horizontal feed mechanism of the magazine-like moving chute are not limited to the ball screw device and cylinder described above.
Various mechanisms such as a rack-binion mechanism, a belt drive mechanism such as a timing belt, etc. can be used.

〔Effect of the invention〕

As described in detail above, the parts supply device according to the present invention uses all magazine-like movable chutes for storing a plurality of parts, and displaces one part of the movable chute between the part loading position and the part unloading position. Since companion parts supplied from the supply section are stored in each component storage section, parts can be quickly and reliably stored in any component storage section.
Further, even when different types of parts are stored in each parts storage section, it is sufficient to provide only a single movable chute, so that the structure is simple and the entire apparatus can be miniaturized.
