Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tile sheathing method, a tile pushing device and a tile sheathing device used in this method.

Tile base (simply referred to as "tile" in this specification)
In the past, the process of packing the clay into saggers, or so-called ``pods,'' for firing was generally done by hand.

However, it is impossible to improve the efficiency and reduce the cost of filling the pods by hand.

This invention was devised for the purpose of automating this process.

Hao, when automating the pod filling work, one tile
Possible methods include packing tiles one by one into a sheath, and pushing a large number of stacked tiles (hereinafter simply referred to as "single stack tiles") into a sheath with the opening facing sideways.

In the latter case, it is easy to think of a method of pushing the stacked tiles straight into the sheath, but it is extremely difficult to pack the stacked tiles into the sheath using this method.

The reason is as follows. That is, as shown in FIGS. 1 and 2, the commonly used pod 1 has a protrusion 3 formed at the center of its bottom surface along the side wall 2 of the pod. A large number of quills 11 are packed in one row each in the left and right portions divided by the portion 3, and the quills 11 in each row are attached to the low step portion 4 formed on the side of the protrusion portion 3. They are arranged vertically in the sheath 1 with a lower inner corner part 12 placed thereon and a corner part 13 located diagonally to the corner part 12 pressed against the side wall 2 of the sheath.

However, the distance between the side wall 2 of the sheath and the protrusion 3 is only about 3 to 5 spaces wider than the length of one side of the tile 11.

Therefore, there may be slight irregularities in the dimensions of the sheaths, very slight deviations in the advancing direction of the stacked tiles or their stacking state during the pushing operation, and slight deviations in the fixed position of the sheaths. Due to reasons such as this, when the stacked tiles are pushed in, the chopsticks are not able to fit within the above-mentioned 3 to 5 mm margin and the pushing position is misaligned. There may be cases where it hits part 3 and makes it difficult to push it in any further.

In other words, it is not always possible to consistently push stacked tiles into the sheath by a linear pushing motion alone.

This invention was made with the aim of solving such problems, and includes a tile pushing cross surface that presses the left or right side and rear surface of the stacked tiles when pushing the stacked tiles into the sheath. Using a push member,
By pushing the stacked tiles into the sheath so as to press them against the inner surface of the side wall of the sheath, it is possible to eliminate the displacement of the pushing position caused by the various causes mentioned above.

Hereinafter, this invention will be explained based on drawings showing one embodiment of the invention. In FIGS. 3 to 6, 20 a + 2
Reference numeral 0b designates a pair of left and right pushing members each having an upright tile pushing intersecting surface made of a folding screen-shaped plate bent into a planar shape or a portion of two intersecting planes.

Each pushing member 20a, 20b has a side surface 21a of the respective tile pushing intersecting surface.

21b are close to each other, and the respective back parts 22a
, 22b are located substantially on the same plane.
The tiles are juxtaposed to the push start position.

In this embodiment, as shown in the figure, two sets of pushing members 20a+20b are arranged side by side on the base plate 23, and each set of pushing members 20a, 20b is connected to a driving means described below.

That is, on the base plate 23, guide shafts 24, 24 whose axial directions match the longitudinal direction of the base plate 23 (horizontal direction in FIG. 5) are horizontally fixed on both the left and right sides (both the upper and lower sides in FIG. 5). The movable frame 25 of the 10-plane pressure type is mounted on the slide bearing 26...
These guide shafts 24° 24 are supported via.

The movable frame 25 is driven forward and backward by an air cylinder 28 fixed to the frame 27.

On the front surface of the movable frame 25, two long plates 29 are fixedly hung down from the left and right sides thereof, and on the other hand, the two sets of four push-in members 2. On the rear surface of each of the back parts 22a and 22b of Oa and 20b, two small plates 30 are fixed to the upper and lower sides of each pushing member, and the plates 30 and 30 of each pushing member are fixed. Moving frame 25
The corresponding elongated plate 29 is the upper and lower two long plates (covering plate 31
, 31.

Therefore, the left and right pushing members 20a are pushed by the operation of the air cylinder 28.

20b moves forward or backward at the same time.

f, f, In order to avoid friction with the base plate 23 during this forward and backward movement, the pushing members 20a, 20
b may be connected to the spring plates 31, 31 in a slightly raised state.

In this specification, the phrase "a pair of pushing members are placed side by side on the plywood" also includes a case where the pushing members are a little apart from the plywood like this.

On the other hand, two small plates 32a + 32b, which are different from the plates 30 and 30, are fixed on the upper and lower sides of the rear surfaces 22a and 22b of the left and right push-in members 20a and 20b, respectively. Then, press the left and right pushing members 20a and 20.
b are connected to each other by small air cylinders 33, 33 at two upper and lower locations via these plates 32a and 32b.

Therefore, when the air cylinder 33 operates, the left and right pushing members 20 a t 20 b simultaneously move left and right to approach or separate from each other.

Reference numeral 34 in FIGS. 5 and 6 denotes a guide shaft, which guides the left and right pushing members 20a+20b through slide bearings 35a+35b fixed to the back surfaces of the left and right pushing members 20a+20b. Guide the movement.

As described above, since the member connecting each of the pushing members 20a to 20b to the moving frame 25 is the spring plate 31, the left and right movement of both the pushing members 20at20b is not hindered.

Note that each pushing member 20a>20b has one end attached to the pushing member 20a or 20b, and the other end attached to the moving frame 25.
The movable frame 25 may be connected to the moving frame 25 by arms (not shown) that are respectively pivotally connected to the movable frame 25.

In the above-mentioned tile pushing device, the left and right pushing members 20a + 20b start pushing the tile by the air cylinder 28, which is one drive means in the front-back direction, and the air cylinder 33, which is one drive means in the left-right direction. While maintaining the posture when juxtaposed in the position, forward and backward movements and approaching and separating movements are performed independently or simultaneously.

An opening 37.37 that penetrates in the vertical direction and is large enough to accommodate the quill mounting table 36 is opened at a predetermined position of the base plate 23 corresponding to the tile pushing start position, and below this opening 37.37. There are many pinions 38...
A rack 39 is vertically supported by a rack 39, and a pair of left and right quill mounting tables 36 and 36, which are slightly smaller than the quill 11, are fixed to the top of the rack 39.

The drive pinion 38 of the rack 39 is a motor 40 with a reduction gear.
The tile mounting table 36, 36 moves up and down by being operated.

In FIGS. 3 and 4, reference numerals 41 and 42 designate tile conveyors arranged at predetermined intervals vertically and horizontally.

Whereas the lower tile conveyor 42 transfers the tile with the glazed side up as it is onto the tile mounting table 36,
Each of the upper tile transport conveyors 41 transports the tiles with the glazed surface facing upward up to the transport end.
The quill clamping plates 44, 44, which are coaxial with the quill clamping plate 43, rotate while holding the tile and turn the tile upside down, so that the tile with the glazed surface facing downward is transferred onto the tile mounting table 36.

As will be described later, when the tiles are stacked, they are stacked so that the glazed surfaces face each other, and the back faces face each other, so to avoid the glazed faces coming into close contact, they are transported separately into upper and lower parts. Styrofoam particles 14 are previously attached to the glazed surface of one of the tiles.

Both tile conveyors 41 and 42 have stoppers 45 and 46.
are provided, and since these work alternately, the tiles carried by each tile conveyor 4L42 are stopped alternately.

Therefore, tiles are alternately transferred from the tile conveyors 41 and 42 to the tile mounting table 36.

Each time a tile is transferred from the tile transport conveyor 4L42, the tile mounting table 36 is lowered sequentially by the thickness of one tile or the size of the expanded polystyrene particles 14, so that the left and right tile placing tables 36 are lowered, respectively. , 36, a large number of tiles 11...
. . . are stacked to obtain stacked tiles io, io with a predetermined interval left and right.

FIG. 6 shows that the stacked tiles 10 obtained in this way are placed on the tile mounting table 36-A, and the tile mounting table 36 is placed in the opening 37.
A state in which the stacked tile 10 is transferred onto the base plate 23 by descending until it enters the interior, and a state in which the stacked tile 10 is pushed into the sheath 1 by the tile pushing device described above are shown.

Then, on the tile mounting table 36, the stacked quills 10 are placed in the sheath 1.
When the pushing members 20a and 20b return to their predetermined positions, they rise again and move the tile conveyor 4L4.
Do not return to the transfer starting position from 2.

A sheath conveying means configured as follows is provided at the front edge of the base plate 23.

That is, 47... is a roller conveyor for carrying the pods 1 whose openings face horizontally from the lateral direction to the front edge of the base plate 23, and at the tip thereof there is a plate-shaped fixed stopper 48, and two sets of fixed stoppers 47 are provided. A plate-shaped movement stopper 50 that is moved up and down by an air cylinder 49 is provided below the running path at a position corresponding to the middle of the tile pushing device.

The first selected pod 1 hits the stopper 48 and stops, and as soon as this is confirmed by a limit switch (not shown), the stopper 50 rises, so the next pod 1 hits this stopper 50 and stops.

The two pods 1, 1 are thus brought into position on the front edge of the base plate 23.

Note that a clamping tool (not shown) may be used to ensure the positioning of the sheath 1.

On the side of the roller conveyor 47, this roller conveyor 4
A sheath mounting frame 52 protruding horizontally and a sheath support rod 53 protruding vertically are fixed to appropriate positions on a rotation shaft 51 extending along the running direction of the sheath 7. A device for transferring the pods is provided.

The rotation shaft 51 is rotated forward and backward by a hydraulic cylinder 54.

In the figure, 55.55 is a belt conveyor for carrying out the stacked quills 10 from the front edge of the base plate 23 after filling the sheaths 1,1.

The aforementioned pod mounting frame 52... is the roller conveyor 4.
When the stacked tiles 10, 10 are pushed into each sheath 1, 1 by the tile pushing device described above, the hydraulic cylinder 54 is operated and rotated. Since the shaft 51 rotates counterclockwise in FIG. 4, the pods 1, 1 are mounted on the pod mounting frame 52...
The pods are lifted up and transferred onto the belt conveyors 55, 55 while leaning on the pod support rods 53.

When the pods 1 that have been transferred onto the belt conveyor 55 are carried away, the rotation shaft 51 is rotated in the reverse clockwise direction in FIG.
... returns to its original position.

7 and 8 show other embodiments of the tile pushing device.

Also in this device, two sets of four pushing members 20a,
20b is connected via a spring plate 31 to a movable frame 25 which is H-shaped in plan.

The pair of left and right pushing members 20a, 20b are both provided with tile pushing intersecting surfaces bent into a planar shape, and the side surfaces 21a, 21b of the respective tile pushing surfaces are close to each other, and the respective back surfaces 22a.

It is also similar to the previous embodiment that the tiles 22b are arranged on the same plane at the tile pushing start position of the base plate 23.

However, in the embodiment, the left and right pushing members 20
a, 20b are air cylinders 3 installed horizontally;
3, the air cylinder 56 itself is operated in the left-right direction, but in this embodiment, the air cylinder 56 itself, which is the driving source, operates in the front-rear direction, and this operation is performed through the mechanism described below. Both pushing members 20at20
By transmitting the information to b, it is possible to change the movement to the left and right.

The air cylinder 56 is fixed to the front end of the H-shaped moving frame 25 via a connecting member 64, and its piston rod 57
An arm fixing member 58 is attached to the tip of the arm.

On the other hand, each rear part 2 of the left and right pushing members 20a>20b
Slide bearings 59a and 59b are fixed to the rear surfaces of 2a and 22b, one on each outer side, and a guide shaft 60 is inserted through these bearings.

In the figure, 61 a + 6 l b indicates both pushing members 20
a, 20b, each back surface part 22a.

22b, and the guide shaft 60 also passes through these guide plates 61a and 61b.

The slide bearings 59a, 59b and the fixed member 58 are connected by arms 62.

The arms 62 are fixed to the bearings 59a, 59b and the fixing member 58 by pivoting.

As mentioned above, the left and right pushing members 20a, 20b
Since the spring plate 31 is connected to the moving frame 25, the piston rod 57 of the air cylinder 56
Even if it stretches, both pushing members 20a, 20b
does not move forward.

Therefore, the forward force generated by the air cylinder 56 is applied diagonally outward from the fixed member 58 to the left and right slide bearings 59a.
, 59b, acts as a force to move the left and right slide bearings 59a, 59b outward, so that the left and right pushing members 20a, 2
0b move in directions away from each other.

When the piston rod 57 contracts, the left and right pushing members 20a
, 20b approach each other.

The H-shaped moving frame 25 is supported by guide shafts 24 and 24 provided on the left and right sides of the base plate 23 via slide bearings 26, and is supported by an air cylinder 28 fixed to the base plate 23.
When activated, the push members 20a and 20b move forward and backward, so that the pair of left and right pushing members 20a and 20b move forward and backward at the same time.

In the figure, reference numeral 37.37 is an opening formed at the tile pushing start position of the base plate 23, which is the opening of the tile mounting base 3 described above.
It is for accommodating 6.

Further, 63 is a tile pushing member 20a. In order to make the movement of 20b smooth, tile pushing member 20a
+ 20 b.

Also in this tile pushing device, the left and right pushing members 20a>20b are juxtaposed at the tile pushing starting position by the air cylinder 28, which is a driving device in the front-back direction, and the air cylinder 56, which is a driving device in the left-right direction. Perform forward and backward movements and approaching and departing movements independently or simultaneously while maintaining the same posture as when moving.

In the tile pushing device shown in FIGS. 5 and 6, the rod of each air cylinder and other necessary parts in the tile pushing device shown in FIGS. 7 and 8 have stacked tiles. In order to reduce the impact of collision with the wall of the pod, a shock absorbing means such as a coil spring is installed.

The tile pushing device and the tile sheathing device according to the present invention are constructed as described above, and the case where the tile sheathing method according to the present invention is carried out using the above device will be explained below. First, two sets of stacked tiles 10, 10 are made as described above on two adjacent tile mounting tables 36, 36 that are close to each other, and these stacked tiles 10, 10 are placed on both tiles. The placing tables 36, 36 are lowered and enter the openings 37, 37 of the base plate 23, so that the tiles are moved and placed side by side in close proximity to each other at a predetermined distance from the tile pushing start position of the base plate 23.

On the other hand, at the same time or before or after this, the roller conveyor 47 of the sheath conveying means places the sheath 1 on the front edge of the base plate 23 with the opening facing toward the stacked tiles 10.10.
is placed horizontally.

Then, the two sets of stacked tiles 10, 10 are stuffed into the sheath 1 by the tile pushing device.

In this case, the tile pushing device operates its left and right pushing members 20 a and 20 b to simultaneously push two sets of stacked tiles 10 and 10 into the sheath 1, and at this time, each stack of tiles 10 and 10 By moving the pushing members 20 a and 20 b a little outward when the tiles enter the sheath 1, the stacked tiles 10 and 10 are placed on the inner surfaces of the left and right side walls 2 and 2 of the sheath 1. Try to push it.

As described above, the pushing members 20a and 20b operate by a combination of forward and backward movements and approaching and separating movements, so when performing the pushing operation of the stacked tiles, the forward movement and separating movement are appropriately performed. Perform the desired operation by combining them.

For example, as shown by the arrows in FIG. 5, both the pushing members 20a and 20b first move forward, and then, when they enter the sheath 1, they perform a forward movement and a separation movement simultaneously. As shown in the figure, each stacked tile 10, 10 is attached to the side wall 2 of the sheath 1 in a diagonal manner to the outside.
. As shown in the figure, both pushing members 20 a
, 20 b temporarily stops this forward movement after the forward movement, performs only a separation movement, presses the stacked tiles io, io against the inner surfaces of the side walls 2, 2 of the sheath, and then moves forward a little again. This is an example.

When the stacked tiles 10, 10 are packed into the sheath 1 in this manner, the sheath 1 is carried out from the front edge of the base plate 23 by the belt conveyor 55 for carrying out the sheath.

When the pod 1 is transferred to the belt conveyor 55, the tiles 11 within the pod naturally tilt slightly and assume a stable posture, as shown in FIG.

As long as the pushing member used in this invention is provided with an upright tile pushing intersecting surface from a part of each of the two intersecting planes, it can be shaped like the folding screen shown in the above embodiment. It only needs to be made of a plate, but other shapes and structures may be used.

On the other hand, when glazed tiles are packed in a sheath, inclusions such as expanded polystyrene particles 14 are interposed between the glazed tiles to prevent the glazed surfaces from coming into close contact with each other, as shown in the above example, but unglazed tiles Since this is not necessary, the stacked tiles are packed in a sheath without any inclusions.

Furthermore, in the above embodiment, two tile conveyors are used to supply tiles to the tile mounting table, but when unglazed tiles are stacked or even when glazed tiles are stacked, inclusions may occur between the glazed surfaces. In the case where a set of two tiles that have been stacked in advance with a tile interposed therebetween are stacked one after another, only one tile conveyor may be used.

When using the tile sheathing method, tile pushing device, and tile sheathing device according to the present invention, when the stacked tiles are pushed in, as described above, when the stacked tiles enter the sheath, By moving the left and right pushing members slightly outward, they are pressed against the inner surfaces of the left and right side walls of each stacked tile 5 sheath, so that each tile making up the stacked tiles is the same on its left side or right side. Aligned on the surface.

Therefore, any misalignment in the advancing direction or stacking state of the stacked tiles that occurred during the pushing operation is completely eliminated, and the stacked tiles aligned in this way are brought to the left or right side wall of the sheath. Even if there are slight irregularities in the dimensions of the sheaths and tiles, or slight deviations in the fixing positions of the sheaths, these will not prevent the front of the stacked tiles from being pushed into the recesses on either side of the protrusions of the sheaths. .

In this invention, since the left and right stacked tiles are pressed against both side walls of the sheath at the same time, even if there is a slight deviation in the fixed position (standby position) of the sheath, this will not affect the pushing of the stacked tiles as described above. This means that there will be no hindrance.

In addition, in this invention, since the left and right pushing members move the left and right stacked tiles slightly outward, when two sets of stacked tiles are placed side by side on the plywood, there is a slight deviation in the juxtaposed position. However, this does not pose a problem.

Therefore, there is the advantage that it is sufficient to use simple positioning means when juxtaposing the stacked tiles.

This invention makes it easy and possible to stack the tiles and push them in as described above, greatly improving the efficiency of the sheathing work compared to the conventional manual work. This reduces costs and greatly contributes to the tile manufacturing industry.
