Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an automatic loading device for a molded product that automatically loads a molded product molded by a transfer press onto a pallet.

[Conventional technology]

Conventionally, a molded product that has been molded by a transfer press and carried out from the press main body is carried to a loading position where the pallet is on standby by a carrying device such as a conveyor, and manually loaded into the pallet.

[Problems to be solved by the device]

However, the loading work by hand-loading takes a lot of time and labor, and the work efficiency is low, and there are problems such as danger in the work.

The present invention has been made for the purpose of remedying the above-mentioned problems, and an object thereof is to provide an automatic loading device for molded articles, which is capable of efficiently loading the molded articles onto the pallet.

[Means and Actions for Solving the Problems]

In order to achieve the above-mentioned object, this invention is a product frit that temporarily receives a molded product carried out by a transfer bar provided in a transfer press main body and raises it to a predetermined height, and a molded product raised to a predetermined height. And a panel loader that conveys the pallet to the molding product loading position, and a pallet feeder that conveys an empty pallet to the molding product loading station,
A pallet lifter that lowers the pallet by indexing as the product is loaded, a pallet conveyor that transfers the pallet with the product loaded to the pallet unloading station, and an empty pallet that transfers the empty pallet from the empty pallet loading station to the delivery position of the pallet feeder. Molding with a transfer device and a pallet transfer device that conveys the full pallet from the pallet conveyor to the full pallet unloading station, so that the molded product delivered from the press body can be automatically loaded onto the pallet. An automatic loading device for goods is provided.

〔Example〕

 An embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes a transfer press main body, which has a pair of transfer bars 3 juxtaposed in the conveying direction of a molded product 2, and the sheet material conveyed to each processing station of the press main body 1 by these transfer bars 3 is Transfer bar 3 after forming product 2 at final processing station W5
Is carried to the idle station i ₃ via the idle station i ₂ .

A product lifter 4 is installed in the idle station i ₃ so as to raise the product 2 received by the transfer bar 3 to a position where the panel loader 6 of the automatic loading device 5 can hold it. There is.

The automatic loading device 5 has a frame 7 installed on the unloading side of the molded product of the press body 1, and the panel loader 6 is attached to the side surface of the frame 7 of the frame 7.

The panel loader 6 has a structure in which a molded product holding member 6b including a vacuum cup and a jaw is detachably attached as an attachment to the tip of a four-bar parallel link mechanism 6a, and the molded product 2 held by the molded product holding member 6b is molded product. The pallets 8 waiting at the loading position P ₃ are sequentially loaded.

The pallet 8 is lifted up to the loading height A shown in FIG. 2 by the pallet lifter 9 installed at the molding product loading position P ₃ , and the index is lowered every time the molding product 2 is loaded. As a result, the loading height A is always kept constant, and when a predetermined number of molded products 2 are loaded in the pallet 8, the full pallet 8 is lowered to the lower limit position by the pallet lifter 9 and is moved downward. It is installed on the installed pallet conveyor 10.

The pallet lifter 9 copes with a change in the index drop amount depending on the type of the pallet 8 or the molded product 2.
A servo motor is used for the drive source 9a so that an arbitrary index drop amount can be accurately obtained.
In order to reduce the load on the servo motor, the pallet 8 is supported by a counterweight or an air cylinder (neither shown) corresponding to the load of the pallet 8 and the molded product 2.

Meanwhile, the full pallet 8 placed on the pallet conveyor 10
Are transported to the pallet unloading station P ₅ by the full pallet transfer device 12 which is transported to the idle station i ₄ and travels on the gantry 7.

The full pallet transfer device 12 has forks 12a for clamping the pallet 8. The fork 12a clamps and unclamps the pallet 8 by a drive source 12b composed of a hydraulic motor, and the pallet 8 is clamped by a hydraulic cylinder 12c. It is designed to go up and down.

An empty pallet transfer device 13 similar to the full pallet transfer device 12 is also installed above the empty pallet transfer station P _{1 of the} automatic loading device 5, and the empty pallet transferred to the empty pallet transfer station P ₁ is loaded. 8 conveys the to the idle station P _2, is placed onto the pallet feeder 14 to wait idle station P _2.

The pallet feeder 14 has a carriage 16 that moves on a guide rail 15 that is laid on the frame 7 in a direction orthogonal to the unloading direction of the molded product 2.

The bogie 16 is provided with a plurality of positioning pins 18 which can be retracted and retracted by the air cylinders 17 at a plurality of positions. The positioning pins 18 position the empty pallet 8 placed on the bogie 16, and the bogie 16 is a bogie. It is adapted to be driven by the drive mechanism 26.

As shown in FIGS. 4 to 7, the cart drive mechanism 17 has an endless timing belt 28 wound between the timing sprockets 27 provided at the idle station P ₂ and the molding product loading station P _3. A part of the carriage 16 is fixed to the timing belt 28.

A drive source 20 composed of a servomotor is connected to one of the timing sprocket 27, and the drive source 20
Thus, by rotating the timing belt 28 forward and backward, the carriage 16 can be reciprocated between the idle station P ₂ and the molded product loading station P ₃ .

The empty pallet 8 transferred from the idle station P ₂ to the molded article loading station P ₃ by the trolley 16 of the pallet feeder 14 is transferred to the pallet lifter 9 and then the trolley 16 returns to the idle station P ₂ and the pallet lifter 9 The panel loader 6 is placed on the empty pallet 8 held above.
As a result, the molded products 2 are loaded.

The above operations are repeated to load the molded products 2, and the full pallet 8 that has been conveyed to the full pallet unloading position P ₅
Are transported to a predetermined place by the unmanned cart 21.

The pallet 8 is provided with a partition plate 8a for preventing the collapse of the loaded molded products 2.

These partition plates 8a can be freely raised and lowered, and are provided on the downstream side of the product loading position P ₃ as shown in FIG.
The partition plate 8a can be raised by rotating a claw body 8c provided on a shaft 8b that rotatably supports the partition plate 8a by an attachment 22a of 22.

Reference numeral 23 in the drawing denotes a molded product extracting conveyor. When the operating molded product extracting mode is selected, the molded product holding member 4a of the product lifter 4 shown in FIG. 9 is retracted and conveyed by the transfer bar 3. The molded product is placed on the sampling conveyor 23, and is carried to the inspection station 24 by the sampling conveyor 23 so that the sampling test of the molded product 2 can be performed.

Further, in the figure, reference numeral 25 is a hand-loading conveyor for transporting the molded product 2 when the automatic loading device 5 cannot be used due to a failure or the like. While the automatic loading device 5 is in operation, it is in a standby state shown by a virtual line in FIG. It is in the position B and can be slid to the position B'when used.

[Effect of device]

As described in detail above, this invention is designed to automatically load the molded products formed by the transfer press onto the pallets and carry them out, so that the work efficiency is higher than that in the case where the products were manually loaded. Not only can it be remarkably improved, but work safety can also be achieved.
