Description

  TECHNICAL FIELD The present invention relates to a plating conveying apparatus that moves a workpiece horizontally after being lowered and dipped in a plating tank to perform plating treatment, and then raises the workpiece and then horizontally conveys the workpiece. The present invention relates to a plating solution cutting device that removes a plating solution that adheres.

  As a liquid draining device in the plating transport device, a jig holding arm of a plating jig on which a workpiece is set is swingably held by a bearing at the tip of a hanger provided so as to be movable up and down on a horizontally traveling carrier, When the upper end of the frame is provided at the top of the frame corresponding to each stop position of the traveling carrier and the hanger is lifted up from the plating tank to the upper limit position, the upper end of the jig holding arm collides with the contact plate, causing a reaction. The plating jig is tilted so that the plating solution is drained from the workpiece. There is no need to install a tilting cylinder at each stop position where liquid draining is necessary, and it is only necessary to provide a contact plate on the upper part of the frame corresponding to the stop position of the traveling carrier.

JP-A-10-280197 (FIGS. 1 and 3)

  However, in the above plating transport device, when the upper limit of the hanger is at the highest position, the plating jig is tilted suddenly like a pendulum, so that the liquid is drained. Also, the jig holding arm can swing freely, so the jig easily swings while the traveling carrier is traveling. It may also occur when it is dropped into the plating tank.

  Therefore, in view of the above-mentioned problems, the problem of the present invention is that it is not necessary to install a tilting cylinder or a backing plate at each stop position, and the liquid is reliably drained in the process of lifting the plating jig from the plating tank. An object of the present invention is to provide a plating conveying device that can be dropped into the plating tank.

  In order to solve the above-mentioned problems, the present invention provides a lifting arm that is supported by a traveling carrier that horizontally conveys a workpiece and can be moved up and down, a carrier bar that moves up and down by translational movement of the lifting arm, and a workpiece set. In the plating transport apparatus including the plating jig suspended from the carrier bar, the lifting arm performs vertical reciprocal vibration with respect to the carrier bar between the lowered position of the carrier bar and the raised position thereof. It is characterized by comprising a plating solution draining device to be added.

  In this transport apparatus for plating, the work can be transported horizontally to the position just above the plating tank and then lowered and immersed in the plating tank, and then the work can be transported to the position just above and then transported horizontally. However, even when the plating jig is lifted from the plating tank, even when the lifting is completed, the plating liquid cutting device can be driven to quickly drain the liquid just above the plating tank. Can be recovered in the plating tank. In addition to being able to change the impact strength and the number of liquid drainage for each product by setting the control software, liquid drainage can be performed on all plating tanks, and washing water can be prevented from being brought into the plating tanks. Of course, since this plating solution cutting device is provided in the lifting arm, there is no need to install a tilting cylinder or a backing plate at each stop position.

  As the plating solution draining device, if the impact force is generated, the reciprocating stroke may be short. Therefore, an inexpensive, lightweight and compact air cylinder can be used.

  The traveling carrier preferably carries a compressor for supplying compressed air to the air cylinder. The length of the air hose can be shortened as compared with the case where the air hose is drawn from the outside of the traveling carrier, and the damage or failure of the air hose can be reduced by reducing the expansion / contraction bending portions of the air hose. Therefore, it is possible to facilitate maintenance management work.

  According to the present invention, there is no need to install a tilting cylinder or a backing plate at each stop position, and the plating transport can be dropped in the plating tank by draining in the process of lifting the plating jig from the plating tank. Equipment can be provided.

It is a front view which shows the lower half of the conveying apparatus for plating. (A) is a front view which shows the non-operation state of a liquid drain air cylinder in the conveyance apparatus for plating, (b) is the right view. (A) is a front view which shows the operating state of a liquid drain air cylinder in the conveyance apparatus for plating, (b) is the right view.

  Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

  The plating conveying apparatus of this example includes a rail R installed over a plurality of cascaded plating tanks 10, a traveling carrier 20 that can travel horizontally along the rail R, and an elevating guide suspended from the traveling carrier 20. A horizontal beam-like lifting arm 1 that can be vertically moved along a frame 21 by a lifting belt 21a, a small compressor 21b mounted on the lifting guide frame 21, and both ends of the lifting arm 1 (only one is shown). A cylinder box 2 having a U-shape, a liquid air cylinder 3 installed in each cylinder box 2 and connected to a small compressor 21b via an air hose h, and both upper and lower plates of the cylinder box 2. It can slide up and down along the vertical guide bars 4 and 4 and pushes and pulls the plunger 3a of the liquid draining air cylinder 3. The carrier hook member 5 that reciprocally vibrates vertically, the L-shaped suspension arm 6 that is suspended and supported by the hook 5a of the carrier hook member 5, and the carrier that spans the suspension arm 6. A bar 7, a plurality of plating jigs 8 suspended from the carrier bar 7, and a plurality of workpieces (members to be plated) 9 set on the plating jigs are provided.

  The traveling carrier 20 is a self-propelled carrier having a driving motor 22 and a traveling wheel 23, and the power / control wiring cable 24 is repeatedly bent along the race R from the power supply outside the carrier to the traveling carrier 20. It is connected to.

  In the plating conveying apparatus having such a configuration, as shown in FIGS. 3 and 4, the plunger for driving the liquid cutting air cylinder 3 is driven even when the plating jig 8 is pulled up from the plating tank 10 even when the lifting is completed. Since the carrier hook member 5 can be moved up and down several times as the 3a is moved up and down rapidly, the carrier bar 7 is moved up and down in translation with respect to the lifting arm 1 via the hook 5a and the suspension arm 6. The liquid from the workpiece 9 can be drained downward, and the plating solution can be collected in the plating tank 10.

  In this example, since it is only necessary to provide the liquid draining air cylinders 3 at both ends of the lifting arm 1 as the liquid draining device, the configuration can be simplified and the equipment cost can be reduced.

  Further, in this example, as shown in FIG. 1, since the small compressor 21 b that supplies the compressed air to the liquid draining air cylinder 3 is carried on the lifting guide frame 21 of the traveling carrier 20, it travels the length of the air hose h. It can be shortened compared with the case where it pulls in from the outside of the carrier 20, and the damage or failure of the air hose h can be reduced by greatly reducing the stretched and bent portions of the air hose h. Therefore, it is possible to facilitate maintenance management work.
