The invention relates to the woodworking industry and can be used in the packaging of goods, mainly lumber.

The aim of the invention is to increase the reliability of the device.

Figure 1 shows a stacker, a cross section; figure 2 is a section aa in figure 1; in Fig.Z - section bB in Fig.2; figure 4 is a section aa in figure 1 in an intermediate position of the gate; in Fig. 5 is a section AA in Fig. 1, in the position for retracting the gates for the magazine.

The stacker contains a roller table 1, a pneumatic cylinder 2 of the transverse feed, a lifting and lowering table 3, a final switch A and two mechanisms for dispensing gaskets - left 5 and right 6, each of which contains a magazine 7 with gaskets 8, and placed in the guide frames 9 the gate 10 with the bracket 11 fixed on it. Between the bracket 11 and the gate 10, the support platform 12 is freely mounted, made in the form of a plate with a bent side 13. Under the gate of the frame 9, the stops 14 and 15 are reinforced, as the gate 10 is connected to the rod of the pneumatic cylinder sixteen.

The stacker works as follows.

The preforms are fed to the roller table 1 from the previous process step. The pneumatic cylinder 2 moves the workpiece 17 from the roller table 1 to the sliders 10, which at this moment are in the extended position. After feeding several blanks on the sliders 10 above the table 3, a layer of blanks 17 is formed, which acts on the end switch 4. At the command of the switch 4, the pneumatic cylinders 16 retract the sliders 10. In this case, the blanks 17 are lowered onto the table 3, and the supporting platforms 12 move together with the sliders 10 only until the board 13 meets the stop 14. After that, the support platforms 12 are stopped, located under the magazine 7, and the sliders 10 continue to move until they exit from under the gaskets 8 of the magazines 7, and as a result, the gaskets 8 are lowered onto the support square Adhesive 12. Then the lowering of the table 3 begins, which continues until the layer of blanks 17 falls below the support pads 12, and the stylus of the end switch 4 is not released.

Next, the return stroke of the pneumatic cylinders 16 and the sliders 10 move towards each other together with the supporting platforms 12. The lower gaskets 8 are removed from the magazines 7 and, located on the moving supporting platforms 12, are transferred over the workpiece spikes 17. Support platforms 12 stop as soon as their side 13 meets the stop 15 (see

figure 5). Continuing movement of the sliders 10 moves the gaskets 8 from the support pads 12 onto the previously collected layer of blanks 17. The blanks are again fed to the sliders 10 by the pneumatic cylinder 2 and the cycle of work is repeated.

Thus, the supply of gaskets in this stacker compared to the prototype is made without falling, which ensures the accuracy of laying gaskets

despite the presence of spikes in the workpieces. Moving the workpieces not along the gaskets, but along the gates when the blank layer is accumulated also increases the reliability of the device.
