JPS594522A - Device for changing slant angle of tiles to be transferred - Google Patents

Abstract

PURPOSE:To reverse the slant angle of tiles, etc. while transferring said tiles by oppositely providing two pairs of elastic wheels of different diameters each pair separately pressing the upper and the lower parts of vertical edges of said tiles, etc. on both sides, in the route on which tiles are transferred in an erected slightly leaning forward. CONSTITUTION:When a tile (a), being transferred in a forwardly leaning erected posture by a transfer conveyor 1, is sent into a slant angle changing device 2, the tile (a) is placed between supplementary transfer belts 22 on the both sides, and is moved with both sides of its vertical edges pressed by the belts 22 run-ning at an equal speed. Then, the lower parts of the vertical edges are first pressed between large-diameter elastic wheels 13 at a turning section formed by a conveyor roll 6, and the tile becomes nearly upright because of the greater peripheral speed of the elastic wheels 13. AT this time, elastic wheels 12 also press the vertical edges between them and, since the peripheral speeds of both wheels 12 and 13 are greater than the speed of the conveyor 1, the tile is slightly separated from the succeeding tiles a1, and its slant angle is reversed due to the action of the elastic wheels 13 before the tile is sent out onto a transfer conveyor 3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention makes it possible to change the inclination angle while transporting tiles in an upright position tilted slightly forward. Elastic rings that press the circumferential surfaces of the upper part and the lower part separately are provided, and the lower elastic ring is actively rotated at a faster speed than the upper elastic shaft, and the difference in rotational speed between the two wheels causes the vertical edge of the tile M to This is characterized in that the lower part is moved quickly on the transfer path to reverse the inclination angle. In addition, the second invention installs a lowered second transfer conveyor with a step in the path on the quill sending side by both elastic shafts, and slides down the quills whose inclination angle is reversed onto the second transfer conveyor. It is characterized by being transported in a horizontal position.

When storing quills in a stocker or taking them out from the storage, it is very advantageous to transport the quills in an upright position slightly tilted forward in order to reduce the bulk in the length direction. However, if the +IJt angle is left on one side, each time you take out the tiles that are sent first from the transfer path, the ones that follow will fall forward and become difficult to handle. I'm in trouble for the first time. The first invention of the present invention is
The purpose of the present invention is to eliminate such drawbacks by reversing the inclination angle of each tile during transportation and converting it into a ζ-aligned arrangement. A second aspect of the present invention is to enable the object to be turned over and slid downward, and to be transported in a horizontal position by a fast-forwarding conveyor installed below.

Preferred embodiments of the invention will now be described with reference to the accompanying drawings.

In the figure, 1 is a first transfer conveyor constituting a transfer route W for transferring tiles a in a slightly forward-inclined state, and 3 is a second transfer conveyor on the same route W, with both conveyors 1.3 A device frame 5.5 of the inclination angle conversion device 2 protruding from the machine frame 4 is provided on both sides of the connecting portion of The shaft of the conveyor roll 8 is rotatably supported by the device frame 5.5. The first and second conveyors 1.3 are tile IQ
The inside of the belt is narrowed so that both longitudinal edges b and b of a are projected, and the gap between the connecting parts 10 between the same curved parts supported by the conveyor roll 6.8 is brought closer, and The gap can also be closed by a horizontal guide plate.

On both the left and right sides of the connecting portion 10, the axes 11 of the elastic rings 12 and large diameter elastic rings 13, which are the main parts of the inclination angle converting device 2, are made perpendicular.
A pair of parts 10 are attached to the side plates 5a, 5a, which are freely supported for approaching and separating by the device frame 5.5. Axis 11.
Reference numeral 11 is fixed to the side plate 5a, and an elastic shaft 12 that contacts the vertical edges on both sides of tiles a and the upper part of b
a rim 14 into which is fitted, a rim 16 into which a large-diameter elastic ring 13 is fitted, which is an integral part of the upper chain ring 15 and the large diameter elastic ring 13 in contact with the lower part thereof;
The mirror shaft 17 on the upper side is fitted in such a way that it can rotate freely. In this embodiment, the diameter of the upper elastic ring 12 is 132 mm, the diameter of the lower large-diameter elastic ring 13 is about 140 mm, and the diameter of the upper elastic ring 12 is about 140 mm.
The material is synthetic rubber, synthetic resin rubber, etc., and is designed to cause elastic deformation as shown in FIG. 4 when the vertical edges come into contact with the edges.

A shaft support plate 18 is attached to the rear side of the shaft 11 to the side plates 5a, 5a, and a pair of pulleys 19 and 20 are attached to the shaft support arms protruding forward and backward from the cedar board 18, respectively. The mirror shaft 21 is fixed to the pulley 20 on the rear side, and an auxiliary transport belt 22-5 for transporting the tiles is wrapped around each of the pulleys 19 and 20. Each of these belts 22 is in pressure contact with the longitudinal edges (b) on both sides of the quills (a) being transferred by the first transfer conveyor 1, and is configured to run in accordance with the transfer speed of the tiles. As shown in FIG. 3, etc., the elastic shaft 12 and the large-diameter elastic ring 13 are arranged immediately behind the portion where the vertical edges of the tiles a and b touch.

The shaft 7 of the conveyor roll 6 of the m-1 transfer iM conveyor 1 is driven by an intermediate shaft 25 which is driven via a chino 24 by an output shaft 23 of a continuously variable transmission driven by a motor installed on the machine frame 4. , rotates through the chino 26.

A full-tooth drive wheel 27 such as the auxiliary transfer belt 22 is provided behind the intermediate shaft 25 and a chain 28 is hung thereon, and a bevel gear 30 at the lower end of the vertical shaft 29 supported by the device frame 5 is engaged with the full-tooth drive wheel 27. do. 27a is an interlocking shaft of the full-tooth drive wheels 27 on both the left and right sides.

The vertical axis 29 includes a mirror shaft 31 corresponding to the mirror shaft 15 of the elastic ring 12, a mirror shaft 33 corresponding to the mirror shaft 17 of the large-diameter elastic ring 13, and a mirror shaft corresponding to the intermediate shaft 25 of the pulley 20. 35 are fixed while allowing adjustment of their movement in the axial direction, and the chenos 32, 34, and 36 are passed to each of them.

-1 One elastic ring 12 is attached to the vertical edges on both sides of tiles a, b
The lower large-diameter elastic ring 13 contacts a length of approximately 50 n in the circumferential direction. The above numerical values are caused by varying the diameter.

Of course, the entire length of each length of contact should be A with uniform pressure.
Although it is not in contact with 1ff1Jib, , b, the lower large-diameter elastic ring 13 has a larger contact pressure and contact time. The upper elastic ring 12 is rotated by the Cheno 32 at a circumferential speed of about 1.5 to 2.5 times that of the first transfer conveyor 1, and the lower elastic ring 13 is rotated by the Cheno 34 at a circumferential speed of about 2.5 times or more. Rotate with. Auxiliary transfer belt 2 driven by Cheno 36
2 applies pressure to prevent the tiles a from falling forward, b
The purpose is to add the same speed as the first transfer conveyor 1. The second transfer conveyor 3 has the same speed as the first transfer conveyor 1.

To explain the operation of this embodiment, the tiles a, which are transferred by the first transfer conveyor 1 in the upright posture of falling forward as described above, are moved by the auxiliary transfer belts 22 on both sides of the inclination angle converting device 2. As the belt 22 runs at the same speed, both vertical edges are pressed and moved, and at the concave bend formed by the conveyor roll 6 of the first transfer conveyor 1, the lower large-diameter elastic ring 13. The lower part of the vertical edge b is pinched by the elastic ring, and due to the fast circumferential speed of the elastic ring, it becomes vertical as shown in Fig. 5. At that time, the elastic ring 12 also clamps the vertical edge b, and since the circumferential speed of both wheels 12 and 13 is faster than that of the first conveyor 1, the following tiles a.

The quills are pulled away from the quills a little, and then due to the high circumferential speed of the large-diameter elastic ring 13, the inclination angle is reversed as shown in FIG.

In this way, the inclination angle conversion of tiles a is caused by being slightly separated from the trailing quills a1 and the preceding quill LQ a 2, and under free vibrational movement in an independent space.
Even if tiles a are decorated, for example, they will not wear out due to abrasion. This is one of the effects of the tilt angle conversion due to the speed difference between the upper elastic ring 12 and the lower large-diameter elastic ring 13.

The side plates 5a, 5a move toward and away from each other depending on the quills, thereby adjusting the corresponding spacing between the upper elastic ring 12, the lower large-diameter elastic ring 13, and the auxiliary transfer belt 22.

In FIG. 7, the second transfer conveyor 3 shown in FIG. The quills whose inclination angle is changed by the large-diameter elastic ring 13 are slid downward as shown in the figure, and the high-speed function of the second transfer conveyor 3 is used to horizontally tilt them backward in the transfer direction so that the quills are sent in one row and vertically. At that time.”
It is effective for inspecting the presence or absence of flaws in the pattern on quill type A, which has two sides.
It is sent by the transfer conveyor 1, and as described above, it is slightly separated from the tiles of f&41 and the inclination angle is changed, so even if there is a patterned surface, it will not rub against each other and be worn out.

Of course, in this embodiment, since the sheet falls immediately after changing the inclination angle, it is appropriate to provide a chute with an appropriate steep angle between it and the second transfer conveyor 3.

As clarified by the explanation given in 6'+1, the invention of ml is based on quills that are conveyed by vertically overlapping each other with a slightly tilted upright shape to shorten the length of conveyance. Separate elastic rings are sequentially brought into contact with the -F side part and the lower part of the vertical edges on both sides during transportation, and the lower elastic shaft is actively rotated at a faster shaft speed than the first elastic ring. 10- Then, each sheet is shaken in order, thereby reversing the forward inclination angle to the backward inclination angle, and distinguishing the one before passing the inclination angle conversion device and the one after passing the inclination angle conversion device. The tiles that would otherwise fall forward can be transported while preventing them from falling forward without using a separate pillow to prevent them from falling forward. This has the effect of simplifying the handling of quills at the end.

In addition, the second invention is such that each tile sent in a forward-inclined posture is separated one after another by an inclination angle converting device, and the front surface of each tile in the direction of transport is placed as an upper surface on a second transfer conveyor. It is a device that can be slid upward and placed in a horizontal position at the high speed of the same conveyor, and has the effect of retaining the function of the first oblique angle conversion device and converting the angle further to a horizontal position all at once. .
