Abstract

The invention relates to the woodworking industry and can be used in lines for laying flat products, mainly wood packaging parts, into a transport package. The device includes a frame 1, a conveyor 2, a gravity tray 3, a visor 4, a pivotally spring-loaded shutter 12, a pusher 5 with rollers 7, a receiving platform 17 on wheels 19 connected to the drive. The articles 28 are conveyed by the conveyor 2 to the gravity tray 3 and the shutter 12 and slide onto the receiving platform 17. The pusher 5 displaces the products along the receiving platform to the abutment wall 18 and pushes together with the products the receiving platform 17, freeing up space for the next part. 1 hp f-ly, 2 ill.

Description

The invention relates to the woodworking industry and can be used in laying lines.

"

flat products, mainly wood packaging parts c. transport package.

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

FIG. 1 shows a diagram of the device, side view; in fig. 2 shows section A-A in FIG. one.

The device includes a frame 1, a feed conveyor 2, a gravity tray 3, a visor 4, a pusher 5, with a drive 6. At the same time, the pusher 5 is made in the form of rollers 7 mounted on an equal-arm lever 8 of the shaft 9. The shaft 9 is fixed on the frame 1 in bearing supports 10 and connected to the drive 6. In the lower end of the chalet on the output

The end of the tray 3 is fixed by means of the hinge 11, the shutter 12, the ratchet is spring-loaded with a spring 13, mounted on the screw 14, rigidly connected with the shutter 2, and set to its original position by a nut 15. On the shutter 12, a spring-loaded shutter 16 is installed. the receiving platform 17, which has vertical walls 18 for products fixed on it, wheels 19, connected by a chain drive and an electromagnetic clutch 20 with an actuator 21. At the platform 17 are grooves 22 for the passage of the rollers 7 of the pusher and the platform the wheels 19 on the rails 23. On the side of the latter on the frame 1 there is an unloader 24 mounted with a 25-wheel drive. On the rails 23 there is a slide

fixed limit switches 26 and 27.

The device works as follows.

The feeding conveyor 2 parts in the transverse direction arrive at the tray 3 under the visor 4 and the subsequent parts are pushed through it and through the curtain 12, onto the table 17 on the side edge. The rotating shaft 9 pushes the rollers 7 onto the formation sheet. The rollers push the part through the spring-loaded cutter 16, press on the previous parts and the stop wall 18, pushing the receiving platform 17 along rail rails 23. At the same time, the rollers 7 roll along the face of the part on the arc of their rotation and firmly press the part 4 previous, laid on edge, details. When the rollers 7 move downward at the moment of release of space for a subsequent part lying on the curtain 12, this part slides onto the rollers 7 of the lever 8 and lowers onto the platform 17 as they turn. Then the part is laid as described in r. Esl for some reason, the part, sliding off the curtain 12, did not have time to lie down on the platform 17, and the rollers 7 were already pressing it, then under the influence of the rollers the curtain rotates relative to the hinge 11, compressing the spring 13. After leaving the working zone, the spring 13 returns the shutter to its original position, the part falls on the receiving platform and the subsequent roller is placed in the package.

If the length of the arc of contact of the rollers along the face is commensurate with the width of the part, then the impulse of force acting from the rollers to the receiving platform 17 is extended in time. Inertial loads associated with changes in the speed of the row and the receiving platform can be reduced. In addition, rollers 7, pushing a number of parts and pad 17, tell it to move by inertia, and at this time

m when laying parts in a row rollers report to the site 17 smaller impulses of force. This allows the recruitment of long rows of parts.

After dialing a row of predetermined length, the wheel 19 of the platform 17 advances on the limit switch 27, which turns off the drive 6 of the pusher 5 and turns on the drive 25. The unloader 24 pushes the assembled row of details of the pad 17, returns to its original position and turns on (limit switches on the path of the unloader not shown) of the electromagnetic clutch 20 of the drive 21. The pad 17 returns to its original position, the wheel 19 advances on the limit switch 26, which disconnects the electromagnetic clutch 20. The process of typing a new number of parts is repeated.
