BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet feeder.

[0002]

2. Description of the Related Art Conventionally, in order to transport and supply pallets, a plurality of pallets are stacked on a trolley from a pallet storage space and transported, and pallets transported by hand are unloaded from the trolley and supplied. There is.

[0003]

However, manually supplying this pallet is extremely inefficient, and automation thereof has been desired. The present invention has been made to meet the above-mentioned demands, and an object of the present invention is to provide a pallet supply device for unloading and supplying the pallets one by one from the trolley as needed.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a support member which is laterally moved by the drive of a drive motor is provided on a base, and the support member of the carry-in drive motor is provided on the support member. A claw body that moves forward by driving is provided, and the pallet mounting body is provided with a storage section for mounting the pallet in an upright state, and a passage gap for moving the claw body is formed in the lower portion of the storage section. The claws are engaged with the placed pallet to push it forward from the base.

[0005]

With the above configuration, the pallet is placed in the upright state in the storage portion, and then the pallet mount is placed on the base. Then, the movable carriage is moved to the pallet supply place. Next, when the drive motor is driven, the support member provided on the base is moved to the rear side of the storage section and is arranged on the rear side of the pallet. Then, the carry-in drive motor is driven and the claws provided on the support member move forward in the passage gap. This pawl engages with the pallet and further moves to push the pallet out of the storage portion. Thereby, the pallet is supplied to the supply place.

[0006]

As described above, according to the present invention, the base is provided with the supporting member which laterally travels by the drive of the drive motor and the claw body which is moved forward by the drive of the carry-in drive motor. Since the pallet is placed upright in the storage section on the base and the pawls are engaged with the pallet to push the pallet forward from the base, the pallet can be removed from the trolley without human intervention. It can be a supply device for a pallet that can be supplied.
