Method for repairing damaged pallets
A multi-step method to repair damaged wooden pallets includes in a first step, the connector members of the pallet element to be replaced are cut through by means of a band saw and then removed. In a subsequent step, both the partially disassembled pallet as well the new pallet elements are transferred into an assembly station, where the new pallet elements are attached to the pallet from the top side. Preferably, damaged bottom parts of the pallet are removed as a module Before the replacement module is attached, preferably the position of the connector elements still present in a top deck board member is electronically scanned, such that the new connector members can be applied in a position offset to the existing connector members.
1. A method of repairing a pallet having pallet members including five top deck board members attached to three stringer board members and three bottom deck board members attached to the stringer board members by connecting block members, wherein the pallet members are attached to each other by connector members, comprising:
cutting through the connector members of at least one pallet member to be replaced and removing the at least one pallet member to be replaced to create a partially disassembled pallet;
transferring new pallet members and the partially disassembled pallet to an assembly station;
scanning and storing positions of connector members present in the partially disassembled pallet; and
applying new connector members in a position offset with regard to the connector members already present in the partially disassembled pallet to attach the new pallet members to the partially disassembled pallet in said assembly station.
2. The method according to claim 1 , wherein the partially disassembled pallet, before being transferred to the assembly station, is fed into a testing station in which absences of pallet members are registered and/or in which positions of connector members present in one or several top deck board members are at least partially scanned and stored.
3. The method according to claim 1 , wherein the at least one pallet member to be replaced is a top deck board member, the top deck board member removed by cutting through the connector members at a height level immediately above a stringer board member.
4. The method according to claim 1 , wherein the at least one pallet member to be replaced is a new top deck board member, a new top deck board member to be attached to a partially disassembled pallet is transferred to the assembly station after a partially disassembled pallet is transferred thereto and, subsequently, the new top deck board member is put on top of the partially disassembled pallet.
5. The method according to claim 4 , wherein the new connector members used to attach the new top deck board member are applied from a top side of the partially disassembled pallet.
6. The method according to claim 1 , wherein the partially disassembled pallet received in the assembly station is firmly held and put under load such that the contour of the pallet is within a norm while the new connector members are applied.
7. The method according to claim 1 , wherein the pallet being repaired is repaired by a modular exchange of pallet members, whereby one or more top deck board member(s) and/or one or more skid(s), and a bottom deck board and three connecting block members associated therewith, are replaced.
8. A method of repairing a pallet having pallet members including five top deck board members attached to three stringer board members and three bottom deck board members attached to the stringer board members by connecting block members, wherein the pallet members are attached to each other by connector members, comprising:
cutting through the connector members driven into the connecting block members assigned to a skid to be replaced;
removing the skid to be replaced to create a partially disassembled pallet;
transferring a new skid to an assembly station;
transferring the partially disassembled pallet to the assembly station and putting the partially disassembled pallet on top of the new skid; and
applying new connector members to attach the new skid to the partially disassembled pallet within said assembly station, wherein all new connector members are applied from a top side of the partially disassembled pallet.
9. The method according to claim 8 , wherein the connector members provided for attaching the new skid are driven through the top deck board member and through the stringer board member into the connecting block member of the new skid.
10. The method according to claim 8 , wherein the skid is removed by cutting through the connector members driven into the connecting block members assigned to the skid at a height level immediately below a stringer board member.
11. The method according to claim 8 , wherein the partially disassembled pallet, before being transferred to the assembly station, is fed into a testing station in which absences of pallet members are registered and/or in which positions of connector members present in one or several top deck board members are at least partially scanned and stored.
12. The method according to claim 8 , wherein the partially disassembled pallet received in the assembly station is firmly held and put under load such that the contour of the pallet is within a norm while the new connector members are applied.
13. The method according to claim 8 , wherein the pallet being repaired is repaired by a modular exchange of pallet members, whereby one or more top deck board member(s) and/or one or more skid(s), and a bottom deck board and three connecting block members associated therewith, are replaced.
