Description

[Detailed Description of the Invention] At least seven cross wheels (f-) or fan blower or spray nozzle, grip the workpiece and spray the surface of the spray inside the housing (crusader goo)! The present invention also relates to a spraying machine or a spraying device having means with a workpiece holder for bringing the spray into the working area of the nozzle.

Spraying is carried out by equipment in a room, regardless of whether the object to be sprayed is a small part that can be transferred or a relatively large part that cannot be transferred. In order to obtain this, means are used to bring the object to be sprayed to the upper part of the flow and rotate it there.
That is, in a spraying device for spraying and treating a relatively large article, the article is delivered to the above means manually or by a handling device. On the contrary, transferable articles can be sent to the falcon or removed from the chamber by means of hot springs, slipways, and the like.

That is, spraying for non-transferable items has the disadvantage that the equipment requires a worker or a handling device that operates to feed or remove the item, and because of this H point, , manufacturing costs increase and the demand for installation space also increases.

It is an object of the invention to improve a spraying system of the type mentioned at the outset, so that non-transferable articles can be removed from a supply conveyor in a flexible manner without increasing manufacturing costs, and that the spraying can be carried out in both directions. The objective is to enable the conveyor to be delivered to the conveyor.

This object is achieved according to the invention by the features of claim 1.

According to the invention, said means additionally perform the functions of the handling equipment hitherto required for acceptance and delivery. If the above-mentioned means are arranged in the spray chamber housing, the demand for installation space is reduced.

The spraying chambers may be formed as seven constituent units, and the spraying chambers may be provided with connections for supply pipes and return pipes for communication with the drug production section. The advantages of this implementation are:
The main feature of spraying, which is the processing area, is that the chamber can be made very small. Spraying is particularly advantageous when processing is to be carried out, in particular as it eliminates the need for intermediate storage before or after spraying in many applications.

Does spraying change the process within the production process? Another possibility of converting the spray chamber housing into three spaces II
This is accomplished by movably supporting at least seven of the +. This makes it possible to spatially separate the place where the parts to be sprayed are transferred from the place where they are delivered.

Further, according to the present invention, it is also possible to perform spraying treatment on articles in separate production lines from a separate chamber.

If the shapes of the articles of the different production lines are quite different, the workpiece holder is designed as a grid-like or mesh-like sieve basket that can be closed with a lid.

The mesh-like sieve basket not only grips and holds these separate members, but also has the advantage that the spraying system of the present invention allows for the spraying and processing of non-transferable articles.

Another advantage of the invention is that the above-mentioned means as a handling device for performing auxiliary operations is provided when the workpiece is made of rubber, for example, and has to be immersed in a container containing liquid nitrogen before spraying. It is possible to use it.

The use according to the present invention is such that the spraying agent preparation section, the spraying agent storage container, and the dust removal device are installed as a central supply device apart from the production line, and seven or more sprays from this feeding device are carried out using a flexible hose such as a hose. Spraying through the tube allows the agent to be delivered. By using flexible tubes, the location of the spray chamber within the production line can be easily changed as needed.

Next, further explanation will be given with reference to the embodiment shown in the drawings. The spraying apparatus shown in FIG. The parts 2 are formed as independent structural units and are interconnected by flexible tubes 3, such as hoses, for supplying and returning the agent. By means of the flexible tube 3 the spray can be mounted at each desired point of use within a predetermined radius cutting the chamber 1 around the preparation section 20.

The communication between the compressed air side and the spray is used to shut off the agent delivery.

For spraying, the agent is passed through the cyclone 9 from the return pipe 3b to the vibrating sieve 1.
1, the particles further reach a negative pressure chamber 10 connected to the suction side pressure of the high-pressure blower P4, where they are separated into fine particle portions and coarse particle portions. The sprayed agent reaches the storage container 5 via the cross feed wheel f-142.

The air containing dirt flowing into the pressure chamber 10 from the cyclone 9 is sucked in by the r-loading cylinder 13 through the piping 14, and in a purified state is sent to the product delivery side and the suction side of the machine 4 through the piping 15. be guided. The amount of air supplied from the high pressure blower 4 is
Since the spray fluctuates greatly depending on the operating state of the piping 1, a bypass 17 incorporating a pressure valve 18 is provided between the piping 14 on the suction side and the piping 16 on the discharge side. The differential pressure necessary for operation is created by the

The blower chamber 1 has a blower chamber housing 19 (see the first diagram), and the blower chamber housing 19 can be accessed by a door 20 which can be operated by a drive device (not shown). The conveyor belt housing 19 is rotatable between three illustrated operating positions about a horizontal axis of rotation 210 in fixed-position pivot bearings 22.

Reference numeral 47 indicates that the workpiece holder passes through the interior of the chamber housing 19 together with the workpiece 24, and the spray passes through the chamber housing 19 through the conical area shown by the broken line in the figure. It represents the process.

The original blowing function is a fibrillation function for the machine ridge.The function of the blowing chamber 10 as a handling device will be explained with reference to FIG. When the workpieces 24 arrive one after another in the spray chamber 1 on the conveyor belt 23 (see FIG. 1), the spray chamber 19 first rotates to the position shown in FIG. 1, and the door 20 is opened. Since the tube body 30 protrudes outward in this state, the first part 1 is simply 1. ! 7 The schematically illustrated workpiece holder (bearing body 35 and angle lever 36) is in the first position 7
It is possible to touch two workpieces with your fingers. Therefore, 10
The pair of tubes 31 is actuated and the tube 30 can be returned to the position shown in solid lines in FIG. 12 into the housing 19. In this second position of the workpiece holder, the door 2
0 is closed, the chamber housing 19 is closed, and the spray chamber housing 19 is
Rotate 10 times to position 449. This position 49 is
The spray is at a location where the bottom of the chamber housing 19 is sloped relative to the gutter assembly 28 so that the agent slides over it and into the assembly 81128. In this position 49, the closing members 6, 7.8 are open and the blower is not exposed to the cross-shaped gate 2.
The sprayed air is guided to the nozzle 50, and the sprayed air is returned to the production section 2 from the chamber housing 19 via the return pipe 3b. During spraying, the workpiece holder (consisting of the bearing body 35 and the angle lever 36 as described above)
From the second position (position W indicated by a solid line in FIG. 2), the spray is directed to the third position also indicated by the 7-point 0 line at the rear end of the chamber housing 19, and from this third position, the conical spray is It is passed back through the area of the agent into the second position and at the same time rotated via the TW, e M+ 39 acting on the hollow shaft 34. Next, the closing section 6 is closed and the supply of the spray agent is cut off, so that only the spray agent on the compressed side flows through the main housing 19 and dust is removed from the initial workpiece.

When the workpiece holder reaches the second position, the cutoff phase 7
, 8 are closed, the spray chamber housing 19 is moved to position 48 in FIG. 1, and the door 20 is opened. The tube 30 is pushed outward from the spray housing 19 until the workpiece 24 is placed on the conveyor belt 23 again, at which time the pneumatic cylinder 44 is activated and the wandering workpiece 24 is removed from the workpiece. IJ IJ- is removed from the object holder.

FIG. 9 is a side view similar to FIG. 2 showing a modification of the spray chamber 1, and in this example, in addition to the Crusader r-) 26, a similar spray nozzle 50 is used. Since the spray chamber 1 has a structure similar to that of the embodiment shown in FIGS. 1-3, the same reference numerals are used for the same parts as in the embodiment shown in FIGS.

The differences in the structure of the spray chamber 1 according to the embodiment shown in FIG. Now, it can be rotated around a vertical axis rather than a horizontal axis. This embodiment is particularly suitable for spraying and treating small workpieces. The workpiece holding section is formed as a sieve basket 51 in the form of a square mesh lattice, and can be closed by a swingable lid 52.

The lid 52 is opened and closed by a rocking lever 53 that is rocked from a pneumatic cylinder 44 by a push lever 42 .

In this example, the shaft 25 of the door 20 is disposed below the chamber 19 and in the vicinity of the annual income ring 28, unlike the above-mentioned sides. The advantage of this configuration is that the door 20 can be pivoted into an approximately horizontal position when taking up a workpiece, in which the door 2o is free of particles that may fall through the basket 51, such as hard plastics. The streamer is caught and the spray is sent into the chamber housing 19 when the cell is closed. The burrs and the spraying agent are returned to the spraying agent making section 2 and distributed in the central portion. In addition, during spraying, the chamber housing 19 is suspended vertically by the pivot bearing 54.
It is swingably supported on a swing shaft 55. In the case of the rotor, the chamber 1 is swung by the electric motor 56 and the rotating device ft'f 57.
It can be swung around 5.

The spray chamber 1 is brought to the intermediate position 1 shown in FIG. 5 to receive the workpiece. In this case 1st place P, the open basket 5] is hot #
5B (the workpiece falls directly into the basket 51 from the conveyor belt 59 by this hole A?-58, or is discharged directly into the hopper 58, for example from a synthetic resin press). Next, the sprayer swings the chamber 1 to the side, closes the door 52, and sprays the basket 51 to the chamber housing 1.
9 and close door 2o. The basket 51, rotating with the hollow shaft 34, is then drawn through the area of the Flfi-like spray agent. The basket 51 should be designed so that the amount of energy absorbed by the grid during spraying is minimized. When spraying the processed workpiece, the basket 51 is positioned below together with the door 52, and the rotary drive device N'39 is used so that the workpiece automatically falls when the door 52 is opened. to stop. The slanted door 20 is vertically positioned below the chamber housing 19.

As shown in FIG. 79g, each spray rotatable about a vertical axis is arranged in chamber 1 and seven or more receivers have one delivery point, and these receivers have one delivery point in the vertical auxiliary shaft 55. They can also be arranged at predetermined angular intervals around the periphery.

In Figure 6 there is shown a spraying chamber which is rotatable about a vertical axis of 1 m550, and which is rotatable about a horizontal axis at different height levels of 41 M Pft. This spraying is carried out in the chamber by the supply conveyor pel)
The tip of the conveyor belt 60 forms a receiving point for the workpiece, and the delivery point is formed by the starting end of the conveyor belt 61 on the discharge side, which is laterally offset in the conveying direction. The workpiece is placed on the carry-out conveyor belt 61 while being rotated by 10 rotation angles of the spray chamber housing in the conveying direction.

In all the embodiments described above, the spray is applied to the chamber housing 1.
is also a handling device, which, in addition to its spraying capability, can accept workpieces at at least seven locations and deliver the workpieces to each of these locations or to another location. The mobility of the spray chamber depends only on which spatial axis and around how many spatial axes its rotation takes place.
