Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shaft coating device that automatically coats various shafts.

[Prior art and its problems]

For shafts that have been machined such as threading on both ends, the machined parts must be masked and painted.

To automate this painting work, a pair of masking plates that mask each end of the shaft by a certain length are moved and adjusted according to the length of the shaft, and a paint machine that moves between the masking plates is moved. It is necessary to control the device so that it starts and stops at a predetermined timing.

For this reason, in the past, the coating machine was started and started based on positioning data for each masking plate that was set in advance according to the length of the shaft, and distance calculation data between the masking plates determined from the positioning data.
We are forced to use extremely complicated controls to stop
The manufacturing cost of shaft coating equipment was high.

[Means for solving problems]

Therefore, an object of the present invention is to simplify the control for starting and stopping a coating machine at a predetermined timing, thereby reducing the manufacturing cost of a shaft coating device.

In order to achieve this objective, the present invention includes a pair of masking plates whose positions are adjusted according to the length of the shaft so as to mask both ends of the shaft by a certain length, and a In a shaft coating device equipped with a coating machine that paints the shaft while moving between masking plates toward the other end, the coating machine starts painting when the coating machine that moves between the masking plates reaches the coating start position on one end of the shaft. A switch that outputs a start signal for the sprayer and outputs a stop signal for the sprayer when it reaches the coating end position on the other end of the shaft is integrated into either a pair of masking plates or one of the sprayers. One of the features is that the switch is attached to the other end, and an operator for operating the switch is integrally attached to the other end.

[Effect]

According to the present invention, when the coating machine reaches the coating start position of the shaft, for example, a switch that is integrally attached to the coating machine is attached integrally with a masking plate that masks the coating start position of the shaft. The sprayer is started by turning on the operator.

When the coating machine reaches the coating end position of the shaft, the switch is turned off by an operator attached to a masking plate that masks the coating finishing position of the shaft, and the coating machine stops.

Therefore, the coating machine can be automatically started and stopped by simple control by simply moving the coating machine between masking plates whose positions are adjusted according to the length of the shaft.

〔Example〕

Hereinafter, embodiments of the present invention will be specifically described based on the drawings.

FIG. 1 is a front view showing an example of a shaft coating apparatus according to the present invention, and FIG. 2 is a side view thereof.

The shaft coating device shown in this example includes a pair of masking plates 1R and 1L that mask both ends of the shaft S by a certain length, respectively, depending on the length of the shaft S.
The coating machine 2 moves between the masking plates 1R and 1L to paint the shaft S.

Then, when the coating machine 2 reaches the coating start position X and the coating end position Y of the shaft S, the coating machine 2
switch 3X that outputs the start signal and stop signal of
3Y is integrally attached to the coating machine 2, and operators 4X and 4Y for turning on and off the switches 3X and 3Y are attached to each masking plate 1R and 1L.
and are integrally attached to each other.

Here, the masking plates 1R and 1L are disposed on an elevating body 6 that can be moved up and down by a cylinder 5, and are configured to move forward and backward with respect to the shaft S from above.

Inside the elevating body 6 are a masking plate moving motor 9 that rotates a ball screw 8 that is screwed into the upper end of a bracket 7 with a masking plate 1R attached to its lower end, and a bracket 10 with a masking plate 1L attached to its lower end. A masking plate moving motor 12 that rotates a ball screw 11 that is screwed into the upper end.
are arranged vertically and inconsistently.

Each motor 9 and 12 is connected to each masking plate 1R set in advance according to the length of the shaft S to be painted.
Each masking plate 1R and 1L is driven forward and backward at a predetermined rotation speed based on the positioning data of 1R and 1L.
is configured to move a predetermined distance in the left and right direction.

The operators 4Y and 4X are attached to the bracket 7 to which the masking plate 1R is attached, and to the bracket 10 to which the masking plate 1L is attached, respectively, so as to be vertically offset from each other.

The masking plates 1R and 1L each have a slot 13 formed at the center of their lower ends through which the shaft S is inserted, and a cover 14 extending from the side edge on the coating machine 2 side toward the end of the shaft S. is installed protrudingly.

Next, the sprayer 2 is attached to the lower end of a bracket 16 that is screwed into a ball screw 15 arranged parallel to the ball screws 8 and 11, and is moved left and right by rotating the ball screw 15 with a motor 17 for moving the sprayer. It is designed so that it can be

Switches 3X and 3Y are attached to the bracket 16 vertically.

The switches 3X, 3Y are, for example, proximity switches, and are mounted at the same height as the dog 18 of each of the operators 4X, 4Y.

The above is an example of the configuration of the shaft coating device according to the present invention, and the operation and effects thereof will be explained next.

First, based on masking plate positioning data preset according to the length of the shaft S, the masking plate moving motors 9 and 12 are driven in a required direction at a predetermined number of rotations, and the masking plates 1R, 1
Adjust the position of L.

In this way, when each masking plate 1R, 1L moves to a position where it can mask both ends of the shaft S by a certain length, the cylinder 5 is activated, the elevating body 6 is lowered, and the masking plates 1R, 1L are moved. He will soon advance to Shaft S.

When the shaft S is completely inserted into the slots 13 of the masking plates 1R and 1L, the operation of the cylinder 5 is stopped.

As a result, both ends of the machined shaft S are reliably masked by the masking plates 1R and 1L, respectively.

In this state, the coating machine moving motor 17 is driven, and the coating machine 2 starts moving toward the coating start position X of the shaft S.

When the paint sprayer 2 arrives at the paint start position The switch 3 is turned on in proximity to the dog 18 of the operator 4X.
Painter 2 is activated by the switch signal output from X.
will be started automatically.

As a result, paint is sprayed from the coating machine 2 and the shaft S is coated. Note that, at this time, the shaft S is configured to rotate at a constant speed.

When the coating machine 2 moves between the masking plates 1R and 1L and reaches the coating end position Y of the shaft S, the switch 3Y installed below the switch 3X masks the coating end position of the shaft S. The operator 4Y is turned on close to the dog 18 attached to the bracket 7 together with the masking plate 1R, and the coating machine 2 is automatically stopped by a switch signal output from the switch 3Y.

As described above, according to the present invention, the coating machine 2 can be started and started by simple control by simply moving the coating machine 2 between the masking plates 1R and 1L whose position is adjusted according to the length of the shaft S. Stopping occurs automatically.

Therefore, as in the past, the paint sprayer 2 is operated based on the positioning data of the masking plates 1R and 1L, which differ depending on the length of the shaft S, and the distance calculation data between the masking plates 1R and 1L determined from the positioning data. This eliminates the need for complicated controls such as starting and stopping the shaft coating equipment, and the manufacturing cost of shaft coating equipment can be significantly reduced.

In addition, in the above embodiment, the switches 3X,
3Y is installed integrally with the coating machine 2, and its operators 4X and 4Y are installed integrally with the masking plates 1R and 1L, respectively. However, the present invention is not limited to this.
It is also possible to install limit switches corresponding to X and 3Y integrally with each masking plate 1R and 1L, respectively, and to attach an attacker serving as an operator thereof integrally with the coating machine 2.

[Effect of idea]

As described above, the shaft coating device according to the present invention uses extremely simple control that merely adjusts the position of each masking plate that masks both ends of the shaft and moves the coating machine between the masking plates. Since the coating machine is automatically started and stopped according to the length of the shaft, it has the excellent effect of significantly reducing manufacturing costs.
