(54) Shot blasting machine for rolled up wire


(57) The present invention relates to a high efficiency shotblasting machine for rolled up wire, which comprises a rotary door which can turn about a vertical rotary axis, and supporting on both faces thereof arm elements on which wire rolls are arranged.
The door can be driven for closing a shot throwing turbine supporting booth.
The main feature of the invention is that a driving assembly is provided, operating between the door and booth in order to rotatively driven the door and causing the shot throwing turbines to be moved toward the wire roll supporting arms.


Description

BACKGROUND OF THE INVENTION



[0001] The present invention relates to a high efficiency shotblasting machine for rolled up wire.

[0002] As is known, conventional rolled up wire shotblasting machines comprise shot throwing turbines for throwing shots against rolled wire, in which the wire rolls are rotatably supported about a rotary axis therefor.

[0003] These prior shotblasting machines conventionally comprise a rotary door which can turn about a vertical rotary axis, the door supporting on the two opposite sides thereof, two shelves including cantilever-wise supported arms, one of said arms being affected by the shotblasting operation, while the other arm being arranged at a loading and unloading position.

[0004] After the shotblasting operation, the door is caused to turn so as to reverse the positions of the two wire roll supporting arms.

[0005] Such a prior arrangement, however, has the drawback that it is necessary to arrange the shot throwing turbines at a peripheral portion of the rotary outer path, and, accordingly, at a comparatively large distance which, moreover, will increase as the arm length is increased, with a comparatively low efficiency of the shot throwing turbines.

[0006] A further prior approach provides to arrange the mentioned wire roll supporting arms on a door which can be driven about a horizontally extending axis, said door being arranged inside a driving apparatus specifically designed for driving the shot throwing turbines toward one another; such an arrangement, on the other hand, requires a very complex construction apparatus, including a foundation of about 3 meters of depth, with a very high construction and operating cost.

SUMMARY OF THE INVENTION



[0007] Accordingly, the aim of the present invention is to overcome the above mentioned drawbacks, by providing a high efficiency roll wire shotblasting machine, allowing the shot throwing turbines to be arranged and held near the roll wire supporting arms, while having a very simple construction.

[0008] Within the scope of the above mentioned aim, a main object of the present invention is to provide a shotblasting machine, which includes a very compact processing booth, so as to provide an overall apparatus of very reduced size.

[0009] Another object of the present invention is to provide such a high efficiency rolled up wire shotblasting machine which is very reliable and safe in operation.

[0010] Yet another object of the present invention is to provide such a high efficiency rolled up wire shotblasting machine which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.

[0011] According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a high efficiency rolled up wire shotblasting machine comprising a rotary door which can turn about a vertical axis and is provided with two door faces both of which support wire roll supporting arms, said door being adapted to close a shot throwing turbine supporting booth, characterized in that said machine comprises moreover driving means, operating between said door and booth, for rotatively driving said door and causing said shot throwing turbines to move toward said roll wire supporting arms.

BRIEF DESCRIPTION OF THE DRAWINGS



[0012] Further characteristics and advantages of the shotblasting machine according to the present invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive embodiment, of said shotblasting machine, which is illustrated, by way of an indicative, but not limitative, example, in the figures of the accompanying drawings, where:

Figure 1 is a schematic top plan view illustrating the booth and rotary door during the operation of the shotblasting machine;

Figure 2 is a further top plan view illustrating the booth and rotary door during a rotary operation;

Figure 3 is a front elevation view illustrating the shotblasting machine according to the present invention;

Figure 4 is a further side elevation view illustrating the subject shotblasting machine.


DESCRIPTION OF THE PREFERRED EMBODIMENT



[0013] With reference to the above mentioned drawing figures, the high efficiency rolled up wire shotblasting machine according to the present invention, which has been generally indicated by the reference number 1, comprises a bearing framework, of a per se known type, and which has been generally indicated by the reference number 2.

[0014] To said bearing framework 2 is coupled a rotary door 3, which can turn about a vertical axis and is provided with two door faces, both of which support shelf elements 4 to which are cantilever-wise connected arms 5, which are substantially horizontally arranged and can turn about respective rotary axes, said arms 5 supporting the wire rolls 6 to be processed.

[0015] The rotary door is specifically provided for closing a booth 10, in which are arranged a plurality of shot throwing turbines 11.

[0016] As shown in figure 1, said turbines 11 are arranged near the wire roll and, accordingly, the efficiency thereof will be greatly increased.

[0017] The main feature of the invention is that, in order to rotatively drive said door, driving means are provided, which operate between said door and booth for driving the shotblasting turbines toward the wire rolls.

[0018] In the disclosed embodiment, a movable door is provided, as shown in figure 2, but it would be also possible to hold said door in a fixed position and drive said booth with respect to the door.

[0019] More specifically, the driving of the shot throwing turbines, which can occur either before or synchronously with the rotary movement of the door, will allow said shot throwing turbines to be held near said wire rolls, during the wire roll processing, while allowing to perform an easy and quick rotary movement as the wire rolls supported by the faces of the door must be reversed, so as to bring to the outside the already processed wire rolls and inside the wire roll to be processed.

[0020] From the above disclosure it should be apparent that the invention fully achieves the intended aim and objects.

[0021] In particular, the fact is to be pointed out that the provision of door driving means will allow to greatly simplify the shotblasting machine construction, while affording the possibility of properly holding the shot throwing turbines near the wire rolls, with a consequent greatly efficient working process.

[0022] The invention, as disclosed, is susceptible to several modifications and variations, all of which will come within the scope of the invention.

[0023] Moreover, all of the details can be replaced by other technically equivalent elements.

[0024] In practicing the invention, the used materials, provided that they are compatible to the intended use, as well as the contingent size and shapes can be any, depending on requirements.
