Abstract

The invention relates to equipment for handling sheet products, and is intended to dispense these products from the foot. The purpose of the invention is to increase productivity. The device contains a magazine with an inclined front wall and a window in the lower part, a drum with needle-like elements located on the side of the magazine window, a roller forming a friction pair with the drum, a planetary gear, whose central wheel is mounted on the drive shaft, and the satellite is rigidly connected to the roller, and a crank-beam mechanism connecting the drive shaft to the drum shaft. The drum consists of disks mounted on its shaft, bearing needle-shaped elements, and a cylinder placed between them, which is mounted on the shaft freely and contacts the roller. 4 il.

The invention relates to equipment for handling sheet products and can be used to dispense sheet products from the foot, for example, during processing, counting and selling.

The aim of the invention is to increase the productivity of the device for the sample delivery of sheet products from the foot.

FIG. 1 shows a device for the sample delivery of sheet products from the foot, side view; in fig. 2 is a view A of FIG. 1; in fig. 3 is a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. one.

The device for single piece sheet products from the foot contains a magazine 2 fixed on its body 1 with an inclined front wall 3 and a window 4 in its lower part, located on the side of window 4 a drum, which consists of disks 6 and 7 fixed to the shaft 5 with needle-like elements 8 and a cylinder 9, which is freely seated on the shaft 5, is placed between the disks 6 and 7. The device also includes a roller 10, which forms a friction pair with the cylinder 9, a drive shaft 11 connected to the drum shaft 5 via a crank-beam mechanism 12 - 14, and planetary and a gear including a central wheel 15 mounted on the drive shaft 11, driven 16 and a satellite 17 rigidly connected to the roller 10 and mounted on the carrier 16 by means of an axis 18.

The inner surface of the inclined front wall 3 and the roller 10 are made of a material with a high coefficient of friction, such as rubber. If necessary, placed in the store 2 stop 19 products can be pressed with a load 20.

The device works as follows.

When the drive shaft 11 is rotated in the direction of arrow B (fig. 1), the movement through the planetary gear 15-17 is transmitted to the roller 10, which as a result rotates continuously. At the same time, the rotation of the shaft 11 through the crank-beam mechanism, consisting of the crank 12, the piston rod 13 and the rocker arm 14, is converted into an oscillatory movement of the shaft 5 carrying the disks b and 7 and the cylinder 9. Since the cylinder 9 is freely mounted on the shaft 5, the oscillatory movement of the shaft 5 is not transmitted to it. Since during rotation of the central wheel 15 in the gear pair: the central wheel 15 - the satellite 17, a force arises that turns the carrier 16 in the direction of rotation of the central wheel 15, the roller 10 presses against the cylinder 9 and causes it to rotate at a constant speed.

The product is usually delivered in one turn of the drive shaft 11. The disks 6 and 7, mounted on the shaft 5, rotate clockwise, grabbing the lower product with the needles 8, and partially remove it from the foot 19. The overlying products bend and brake TC inclined front wall 3. Upon further rotation, the disks 6 and 7 introduce the product between the cylinder 9 and the roller 10, stop and, turning counterclockwise, return to their original position, and transporting the product to full output from the device the roller 10 and the cylinder 9 rotating under its influence. The rotation of the cylinder 9 does not lead to the removal of subsequent products from the foot, since this is inclined by the inclined front wall 3. If until the end of the full rotation of the drive shaft the product has not been completely issued (i.e.

the length of the product exceeds the path of the roller 10 per revolution of the drive shaft 11), the device’s actions are repeated, however, the needles 8 are in contact with the same, already partially

issued by the product and do not remove the overlying product. Since the linear speed of the disks b and 7 is lower than the speed of the roller 10, the interval between the output products is provided in all possible cases of length and arrangement of the products.

Due to the fact that the withdrawal of products does not stop with the return movement of disks with needles, the proposed device has high performance and allows the production of sheet products of different thickness, length and stiffness, as well as the delivery of products of small sizes, which makes it

very effective in handling items such as labels, labels, tickets, etc.
