Abstract

PURPOSE:To lift workpieces one by one for securely taking out them by pushing them from the lower one of stacked workpieces. CONSTITUTION:A lift motor 40 is driven to pivot a screw rod 35, elevate rods 28, 28, a lift plate 26 from a through hole into a lift hole of a pallet and a workpiece 24. And the uppermost workpiece 24 abuts against adsorbing boards 44, 44' to be adsorbed and held with vacuum. Then, the motor 40 is driven reversely to lower the lift plate 26 and form a space between the uppermost workpiece 24 and adjacent lower one 24. Thereafter, when a transfer conveyer belt 45 is driven, claws 54 are moved to be hooked on an end of the workpiece 24. As the claws 54 pass between both adsorbing boards 44, 44', the workpiece 24 is transhipped onto a transfer conveyer belt 57 and transferred from said conveyer 57 to a desired working place.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a transshipment and transfer device for thin plate workpieces.

(Prior art) Conventionally, the method of taking out thin and fragile ladle materials such as ceramic substrates from a cassette is to stack ceramic substrates on a pallet and push them out one by one from the bottom of the pallet. Ta.

(Problems to be Solved by the Invention) However, in the above method, the workpiece cannot be smoothly processed at 12 hours due to friction between the ceramic substrates or slight misfiring or warping caused by firing the ceramic substrates. There were cases where the workpiece could not be taken out, making it an unreliable method of transporting the workpiece.

Therefore, the present invention provides a device that can push up seven workpieces at a time and reliably take them out.

[Structure of the invention]

(Means for Solving the Problems) The transshipment and transfer device for thin plate workpieces according to the present invention is

The transport conveyor belt ≠ for transporting the workpiece 211- picked up in '4' is installed below the discharge side of the transport conveyor belt 45. It is something.

(Embodiment) An embodiment of the present invention will be described in detail based on the drawings. ．． --- An oval trunk with a space in the center! is supported. Then, the upper blade of the arcuate end of the trunk and evening space≠ is supported at an angle of 10 degrees by a bearing provided on the pulley 6 body 2. - The force shaft 10 is driven by a speed reducer /3 fixed to the lower surface of the main body 2 and supported by a support frame 16 and a conveyor drive motor /≠ fixed to the lower surface of the support frame 16. 7. A belt 15 is suspended between the meat pullers 6 and 7, and a large number of pallets 16.1 are attached to the belt 15.

Furthermore, the pallet 16 is provided with casters 2/ and 2/' at two locations on the lower surface of the opposite side of the fixture /7 so that it can run on the trunk j. Also, palette 1
6 has a pillar hole 22.6 equidistantly inside the diagonal line 0-0 as shown in FIG. :22' to 8'/'f.

These pillar holes 22, 22' are provided in two places at a time,
The pillars 23, 23' and 23' are formed so that the mounting positions of the pillars 23 and 23' can be changed to correspond to the size of the workpiece) μ and -11 (see FIG. 6).

Then, drill two H-shaped lifting holes in the center so as to leave holes 22, 22', -- for each pillar.

On the other hand, the track j is provided with a through hole 27 (see FIG. 3) in a part of the straight portion thereof, through which a push-up plate 26 described below can pass. The push-up plate 26 is formed in an H-shape (see figure ≠) so that it can pass through the lifting hole 2, and has two lifting rods 2f, 2, r' fixed to its lower surface. . Both lifting rods λI were fixed to the guide cylinder, and the hanging plate 3/ (see Fig. 7), which passed through the guide tube 1.22' and passed through the guide tube 7', was fixed, and the hanging plate 3/ Two support rods 32, 32' are fixed to support a support plate 33 attached to the lower ends of the support rods 32, 32'. Then, the screw rod 3 supported by the bearing 31/l (see Figure 3) provided on the hanging plate 3 is inserted through the connecting plate 30 and the support plate 33, and It is rotatably supported. An elevating tool 37 screwed onto the threaded rod 3j is fixed to the upper surface of the connecting plate 30, and the push-up plate 26 is raised and lowered via the elevating tool 37 as the threaded rod 3j rotates. A chain wheel 3 is pivotally attached to the lower end of the screw rod 3j, and is fixed to the lower surface of the support plate 33. It is designed to be driven by placing a chain belt ≠ノ between the two.

Also, above where the track-like through holes 27 are located, there are a number of suction holes 4'3. --Suction cup II-44IA (
(see Figure 7.1) are installed at intervals S.

The inner suction cups 4L≠, 44 are formed into a key shape as shown in Fig. When the object 2≠ comes into contact with the suction cups I/L≠ and ≠Hiroshi, a vacuum circuit is opened by a solenoid valve (not shown), and the object is suctioned by the suction hole≠3.

On the other hand, the upper blade of the suction plate 44' is fixed on the main body through the space of the conveyor cock j, and the conveyor leg ≠ B (see Figure 3) is used to support the conveyor. The plate ≠7 is fixed parallel to the direction of the pallet running force, and the two conveyor support pieces Il-d and ≠g' are attached to the conveyor support &4'7 at an interval perpendicular to the direction of the pallet running force. Fix it so that it reaches the outside of the conveyor support piece ≠ g,

(Function) This embodiment is configured as described above, and the workpiece 211
- are stacked on the pallet 16 (see Fig. 6) and are held by Hiromoto's pillars 23, 23', - - to prevent them from falling off. Then, each pallet /6 moves on the trunk j by the drive of the conveyor drive motor /1A, and stops at the transfer position (the place where the through hole 27 is provided). After that, the lifting motor 4LQ is driven to rotate the terminal bar 3j, and the lifting rod 21.21' is raised, and the push-up plate 26
is raised through the through hole 27 into the lifting hole 2 of the pallet 16, and the workpiece 24t is raised. Then, the uppermost machining #, 2≠ is brought into contact with the suction cup lI-≠, 44' (7. Hold it by suction in a vacuum [7. The push-up plate 26 is lowered by driving (~) to form a gap between the uppermost workpiece 24' and the next workpiece 211-.

After that, when the transport conveyor belt is driven, the claws!
≠ moves and becomes in a state where one end of the workpiece 21I- is hooked, and Tsume Jhiro is placed on the inner eye board ≠Hiro.

As the workpiece passes through tI-≠', the workpiece ≠ is transferred to the carrying-out conveyor belt tuff, and is conveyed from the carrying-out conveyor belt tuff to a desired processing location.

Thereafter, the push-up plate 2tIL is raised again to suction the second-stage workpiece to the suction cup 44'.

After that, transshipment is carried out by repeating the previous method one song at a time.

Note that the shape of the push-up plate 26 is not limited to the H-shape;
It is only necessary to match the shape of the pallet 16 for raising and lowering the pallet 16 to the shape of 25. [Effects of the Invention] In the present invention, the workpieces are pushed out from below the stacked workpieces, so the workpieces are not damaged. The extrusion does not become smooth due to warping or warping of the workpieces, and the workpieces can be separated one by one without rubbing against each other, and can be taken out reliably.
