Description

  The present invention relates to a tray take-out apparatus that accommodates a plurality of workpieces, takes out trays stacked in multiple stages from the inside of a tray changer apparatus, and supplies the trays onto a tray conveyor.

  An apparatus as shown in FIG. 7 is generally used as a method of taking out the trays accommodated in a stacked state in the tray changer from the inside of the tray changer and supplying it to a conveying device such as a conveyor.

The tray take-out apparatus of FIG. 7 used for taking out the tray from the inside of the tray changer is provided with a pusher that operates in parallel to the tray transport direction, and pushes the tray forward from the rear of the tray changer by the pusher. In the case of this method, since the cylinder that is the pusher drive unit is mounted in a state of protruding from the tray changer main body, the tray changer main body becomes large, and thus a large space is required for installation of the apparatus.
JP-A-2001-220018 FIG.

  The present invention is simple and small in the configuration of the tray take-out device used when taking out the trays stored in a state where the trays are stacked in multiple stages from the inside of the tray changer. The purpose is to provide a device that can be installed.

  As a means for solving the above-described problems, the present invention includes a cylinder that moves forward and backward by fluid pressure, a guide mechanism that includes guide rods and linear bushes disposed on both sides of the cylinder, and a cylinder. A device configuration in which a tray take-out device constituted by a tray hooking mechanism having a swingable cam that performs advancing and retreating operations is arranged between belts of a tray conveying conveyor that is composed of a plurality of belts arranged in parallel and rotating. It was.

  By adopting the tray take-out device having the above-described configuration, it is possible to arrange the pallet take-out device between the belts of the hollowing conveyor that rotates with the two belts arranged in parallel. 7 does not protrude from the apparatus as in the prior art shown in FIG. 7, and the installation space of the apparatus can be reduced.

  Further, since the tray take-out device is formed with a very simple device configuration, an inexpensive tray take-out device can be provided, and the equipment costs for the conveyance or assembly line can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the tray take-out device of this embodiment is provided on both sides of a fluid pressure cylinder, a fluid take-off cylinder that is a drive part, a tray take-out mechanism part that moves forward and backward by the cylinder, and is described above. It is an apparatus constituted by a guide mechanism unit that guides a tray take-out mechanism unit that performs an advance / retreat operation.

  The fluid pressure cylinder 23 serving as a drive unit is configured such that the piston rod of the fluid pressure cylinder 23 is attached to the side plate A17 of the mounting base composed of the base 16 and the side plate A17 and the side plate B18 fixed so as to face the base 16. It is attached in a state protruding from the side plate A17.

  A take-out base 11 is attached to the piston rod of the fluid pressure cylinder 23 via a joint 10.

Bearings 15 are attached to opposing positions on the side plate A17 and the side plate B18 of the mounting base, and the guide rod 14 is held by the bearings 15 so as to be able to advance and retreat.
One end face of the guide rod 14 is directly fixed to the take-out base 11, and the other end face is fixed to the take-out base 11 via the connecting plate 13 and the guide frame 12.
A take-out base 11 that is guided by a guide mechanism portion composed of a bearing 15, a guide rod 14, and a guide frame 12 and that can be moved back and forth by a fluid pressure cylinder 23 has a U-shape and is formed on two opposing surfaces. A cam 4 that is swingably supported by a fulcrum shaft 6 is provided.
A spring pin A5 is attached to the cam 4, and a spring pin B24 attached to a surface orthogonal to the surface to which the spring pin A5 and the fulcrum shaft 6 are attached by a lock nut so that the amount of movement can be freely adjusted is a spring. The cam 4 is always brought into contact with the cam stopper 7 disposed on the side of the spring pin B24 by the spring force.

Next, the operation of the tray takeout device of the present invention will be described.
When fluid pressure is supplied to the advance port 20 of the tray take-out device 1, the piston rod starts to advance in the left direction in the drawing.
When the piston rod starts moving forward, the take-out base 11 connected to the piston rod via the joint 10 also starts moving forward while being guided by a guide mechanism constituted by the bearing 15 and the guide rod 14.
When the take-out base 11 moves forward and the cam 4 that is swingably disposed on the take-out base 11 comes into contact with the tray 21 accommodated in the trace stocker 2, the cam 4 is pushed by the tray 21, and the fulcrum shaft 6 The cam 4 turns clockwise until the cam 4 reaches the state shown in FIG. 3. When the cam 4 reaches the state shown in FIG. 3, the take-out base 11 advances while the cam 4 is in contact with the bottom of the tray. The forward end stopper 8 comes into contact with the stopper plate and stops the forward movement. At this time, since the cam 4 is in a position protruding from the tray 21, the cam 4 is turned counterclockwise about the fulcrum shaft 6 by the spring force, and stops the turning operation by contacting the cam stopper 7.
When the fluid pressure is supplied to the backward port 19 after the forward operation of the fluid pressure cylinder 23 is finished, the take-out base 11 connected to the piston rod and the piston rod via the joint 10 starts to move to the right in the drawing. At this time, since the cam tip is located above the bottom surface of the tray, the cam 4 comes into contact with the tray 21 and retracts the piston rod take-in base 11 to pull the tray 21 rightward in the drawing, and the take-out base 11 moves to the side plate A17. The operation is completed by abutting against the backward end stopper 9 disposed in the position.

  By adopting a simple device configuration, it is possible to easily cope with a design change in accordance with a workpiece, and since the device configuration has high rigidity, it can be applied to various devices.
