Description

DETAILED DESCRIPTION OF THE INVENTION A1.Object of the invention (industrial field of application) The present invention is a vertical double-sided nailing device used in the industry of manufacturing pallets for hawk grids. In detail, the upper and lower face plates are attached to both sides of the crosspieces erected on the trolley, and after that, the trolley is sent to a nailing machine and the upper and lower face plates are nailed to the crosspieces at the same time to create a product pallet. Regarding the hitting device.

(Prior art) Conventionally, as a nailing machine used in the industry of manufacturing pallets for hawk grit, as shown in FIG. The material is arranged so that the openings of the faceplates are laid flat or at appropriate intervals, and after the assembly, the construction material is advanced to the nailing machine 58 by the conveying means 57, and the openings of the faceplates are nailed to the crosspieces by the operation of the nailing head 59. When finished, the semi-finished product is returned to the assembly position by the conveyance means 57, reversed by the reversing means 60 so that the side with the face plate opening facing is on the lower side, and the lower face plate C is lined up on the crosspiece A, and the conveyor means 57 Proceed to the nailer 58 again,
This structure is such that the face plate C is nailed to the crosspiece I by the operation of a nailing head 59, and the products with both sides nailed are sent to a stacking table 61 at the rear by a conveying means 57 to be stacked, and when the required number of stacks are stacked, it is sent out.

Two nailing machines 63.
64 are arranged at a predetermined interval, and an automatic reversing means 65 is provided between these nailing machines 63 and 64, and the upper face plate opening is placed on the crosspiece I placed flat at the front of the conveyance path 62. The mechanism is advanced to the position of the nailer 63 on the front side, and the opening of the face plate is nailed to the crosspiece by the operation of the nailing head 66, and the nailing is later advanced to the position of the reversing means 65 so that the opening of the face plate is downward. Place the lower face plate C on top of the inverted crosspiece A, move it to the position of the nailer 64 on the rear side, and press the nailer head 67.
There is a structure known in the art in which the face plate C is nailed to the crosspiece I by the operation of , and the products after the double-sided plates have been nailed are stacked by a stacking machine 68 and sent out when the required number is reached.

(Problems to be Solved by the Invention) Among the conventional nailing devices described above, the former performs nailing of the upper plate and the lower plate in two steps, and furthermore, a returning and reversing process is added in the middle. There are problems in that the work takes time, which does not improve production efficiency, and that two workers are required to reverse the process, which increases labor costs and increases the manufacturing cost of the pallet.

The latter uses two nailing machines, so once the first nailing machine finishes nailing the upper face plate, the crosspiece is advanced to the next nailing machine and reversed, so the return process in the former can be omitted. However, the fact that the upper and lower face plates are nailed in two steps is still the same, so the production efficiency of pallets is still low because the work time cannot be reduced significantly. , and an automatic reversing means is provided between them, which has the problem that the equipment cost is more than twice that of the former, and the area of the equipment also increases, leading to an increase in the -layer manufacturing cost.

The present invention was made in order to solve the above-mentioned conventional problems, and by erecting the structure of the crosspiece and the upper and lower face plates, it is possible to simultaneously nail both sides of the plates with a table nailer. The object of the present invention is to provide a nailing device in which the production cost of pallets can be greatly reduced by significantly increasing efficiency and simplifying and downsizing the device.

(Means for Solving the Problems) The means of the present invention for achieving the above-mentioned object includes a cart that is guided by a guide and moves back and forth between a material arrangement position and a product delivery position, and means for supporting the required number of crosspieces at required intervals; face plate support means for attaching face plates to both sides of the crosspieces; The present invention resides in the structure of a vertical double-sided nailing device for a pallet, which is equipped with a nailing machine in which nailing means are respectively associated with both sides of the pallet.

(Function) The double-sided nailing device according to the present invention adjusts the spacing of the crosspiece support means appropriately when the cart is waiting at the assembly position, arranges and fixes the necessary number of crosspieces at predetermined intervals, and fixes the placement of the crosspieces. Once finished, determine the position of the support means for the face plates depending on whether the upper and lower face plates are to be hammered solidly or spaced, attach the upper and lower face plates to both sides of the crosspiece, operate the face plate support means, and attach the double-sided plates. Finish the mechanism by pressing it against both sides of the crosspiece.

Once the mechanism is completed, move the cart to the position of the nail gun, stop it when the first nail driving position corresponds to the nail nozzle, and set the device to operate according to the number of strokes to be driven in advance. If the tips of the nail nozzles are pressed against the upper and lower surfaces respectively by the movement of the moving rod, and then the driving shaft in each nail nozzle is advanced by the interlocking body, all the nails are driven at once and the nails in the first row are driven. To finish driving, move the nail nozzle backward and advance the cart. When the next nail driving position corresponds to the nail nozzle, stop the cart, press the nail nozzle against the face plate, extend the driving shaft, and drive the nail. By performing the operations in sequence, a pallet with upper and lower face plates nailed to both sides of the crosspieces will be completed. Therefore, this pallet is sent to the delivery position at the rear of the nailer, taken out to the processing table by the take-out means, laid down on its side, and while being fed onto the processing table, the uneven upper side is trimmed to make an accurate product and stacked. The material is stacked on the table, and during this time the cart returns to the working position and finishes working on the next material, so when the work is finished, it is sent to the nailer and the nailing operation is repeated. can be manufactured automatically and efficiently by double-sided nailing.

In addition, when nailing as described above, the nailing position may be set by the operator's judgment, but actuators are provided on the trolley side in alignment with each crosspiece, and the nailer side is set in correspondence with these actuators. If a detector is provided in the machine, the operator can be detected by the detector, the truck can be stopped, and the nail driving position can be automatically aligned with the nail nozzle. However, since this is just a means commonly employed in this industry, detailed explanation will be omitted.
