Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a lightweight and easily damaged dish plate that is molded from a synthetic resin foam such as expanded styrene, and has a decorative material containing cement inside with a flat top surface. The present invention relates to a block decoration device for fitting the surface of a formed concrete block and layering a decorative material in a face plate onto the surface of the block.

As is well known, the surface of a concrete block is tasteless and monotonous, so various proposals have been made to add decorative effects to it, and these have achieved some success.

However, the surface decoration pattern obtained by the conventional method is uniform, and there is no freedom to vary it arbitrarily.

Therefore, as described above, the present invention involves fitting the surface portion of a molded block into a dish plate containing a decorative material layer, thereby depositing the decorative material layer on the block surface, thereby covering the surface of the block with the decorative material. Based on the type, quality, and color of the various materials blended as well as the uneven pattern on the inner bottom of the plate,
A variety of decorative effects can be achieved by mechanizing the plate plate made of synthetic resin foam, which is easily damaged, with extremely high efficiency. The invention will be described with reference to one embodiment.

A is a plate plate made of synthetic resin foam, into which a certain amount of decorative material containing cement is put, and for example, by vibration, the decorative material is made into a layer a with a flat top surface within the face plate. It is advanced by a transfer device 1 that is driven intermittently at a constant pitch, and stops when it reaches the fitting position 1a with the block.

The plate A has a certain depth, and its inner shape is slightly more dog-shaped than the surface of the block B.

The block B is advanced towards the mating position 1a with a second transport device 2 arranged at right angles to the transport device 1 and is parked on the front end of the second transport device adjacent at right angles to the mating position 1a. Stop at position 2a.

The present invention picks up a block that has come to the standby position 2a on the front end of the second transfer device with its surface facing downward, and
The block is lowered onto the fitting position 1a by crossing the distance between a and 13, and the surface part of the block is fitted into the inside of the decorative material layer-containing tray plate which has reached the fitting position and has stopped. It is.

As will be described later, the face plate is positioned at the fitting position 1a or a stop position close to this, and the block is positioned at the standby position 2a or a stop position close to this so that they can be fitted accurately.

Reference numeral 3 denotes a frame that is placed on the floor and straddles the mating position 1a and the standby position 2a in series, and is located exactly between the two positions 1a and 2a.
is rotatably supported, and one end of a swing arm 5 of a predetermined length is fixed to the inner end of each of the left and right shafts 4 facing in the same direction.
One end of the endless chain 6 is hung on the chain wheel 6a fixed to each outer end of the frame 3, and the chain wheel 6b, on which the other end of the chain 6 is hung, is fixed to a drive shaft 6' supported on the earthen wall of the frame 3. Then, the rotational force of a motor M with a brake that can be rotated in forward and reverse directions is transmitted to the drive shaft 6', and the rotation of this motor M causes the shafts 4, 4 to rotate at low speed through chain transmission, and one end is fixed to this shaft. The pivoting arms 5, 5 thus rotated are made to pivot together.

Between the left and right rotating arms 5, 5 are two downwardly directed jaws 7a, 7.
b, and an actuating device that closes the jaws to grip the block or conversely opens the jaws to release the grip on the block, for example, a gripping device 7 consisting of a piston cylinder 7', and A short arm 8 attached to the side and protruding upward approximately in the middle of both jaws has two upper and lower protruding shafts 8a,
8b is fixed outward, and a jawed wheel 8' is attached to the tip of each shaft.
is rotatably attached to the lower protruding shaft 8b, and a roller 8'' is rotatably provided in the middle of the length of the lower protruding shaft 8b. Slide the roller 8'' inside and penetrate it.

Tires of a wheel 8' having a vertically protruding shaft are slidably fitted on the opposing inner surfaces of the left and right side walls 3' of the frame, and are used to raise and lower the holding device 7 directly above the fitting position 1a and the standby position 2a, respectively. connecting roads 9-I and 9-n and the upper ends of both hoistways,
A guiding device 9 consisting of a lateral channel 9 and a plate, on which at least the wheels 8' of the lower projecting shaft roll, is provided by means of rail plates 9'.

Therefore, in order to fit the block located at the standby position 2a into the face plate that has arrived at the fitting position 1a of the transfer device 1, open both jaws of the gripping device, rotate the swing arm 5 in one direction, and move the block onto the standby position 2a. The upper and lower wheels 8', 8' are guided to a certain rear hoistway 9-H to lower the gripping device onto the standby position 2a, and then the jaws are closed to grip the block.

When the swinging arm 5 descends to the position where both jaws grip the block, it hits the stopper 10a and is prevented from further swinging, and at the same time kicks the limit switch to stop the motor and issue a signal for the jaws to grip the block.

When the jaws grip the block, the motor begins to reverse, causing the pivot arm to pivot in the opposite direction.

For this reason, the gripping device 7 guides the upper and lower wheels to the rear hoistway 9-I in the waiting position by the initial upward turn of the swing arm 5, and ascends. When it escapes, the lower wheel rolls over the connecting path 9 by the horizontal rotation of the arm, crosses between the standby position 2a and the mating position 1a, and moves to the front hoistway 9-I above the mating position. After reaching the upper end, the upper and lower wheels are guided to this hoistway by downward rotation of the rotating arm 5, and descend onto the fitting position 1a.

When the downward surface of the block descends to a point slightly above the plate plate stopped at the mating position, the swing arm 5 kicks a limit switch (not shown), and the motor stops and the brake is applied at the same time. The rotation of arm 5 stops.

Thereafter, for example, by controlling with a timer, only the brake is released after, for example, 1/2 second, and the rotating arm rotates due to the weight of the rotating arm 5, the gripping device 7, and the block B, and the surface of the block is placed in the plate. It fits and presses against the decorative material layer a in the face plate.

Of course, the swing of the swing arm 5 based on its own weight, such as the weight of the block, is finally regulated when it hits the stopper 10b, and at the same time, the swing arm kicks the limit switch to issue a signal to open the jaw.

In this embodiment, one of the jaws 7a is a fixed jaw, and the other jaw 7b is a movable jaw that is moved toward and away from the fixed jaw 7a by a cylinder 7l. In this case, the center of the standby position 2a of the book in the front-back direction is Move the fixed jaw 7a slightly forward of the center of the rear hoistway 9-I, open the jaw, and place it so that the inner surface of the fixed jaw 7a that descends does not hit the block in the standby position, and then open the movable jaw after descending. moves closer to the fixed jaw, and when gripping the block, the block is moved back a little.

In this case, even if the block is fitted onto the face plate in the fitted position and the movable jaw 7b is opened to release the grip on the block, the inner surface of the fixed jaw 7a remains in contact with the side surface of the block.

Therefore, when the transfer device 1 performs the next intermittent drive, or when the gripping device 7 is raised beforehand, the inner surface of the fixed jaw and the side surface of the butt are in friction.

Therefore, when the block is fitted into the face plate and the movable jaw is opened, the push plate 1 is actuated by the piston 11 provided at the fitting position.
It is preferable to push the block fitted into the face plate by 1' in a direction away from the inner surface of the fixed jaw 7a, and to laterally shift the face plate together with the block on the transfer device 1.

Of course, it is also possible to pivotally attach two jaws to a base body equipped with a vertically projecting shaft so that both jaws approach each other and grip the block by the operation of a piston cylinder. In that case, the standby position 2a and the rear elevation The piston 11 can be omitted since the centers of the passages 9-I can be aligned and the inner surface of each jaw separates from the side surface of the block when the gripping device is opened after the block has been fitted into the face plate.

In this embodiment, the gripping device 1 is moved approximately linearly by the swing arm 5 in the vertical direction along the front and rear hoistways 9-1 and 2, and in the lateral direction along the lateral communication path 9-1. However, the gripping device 7 slides the roller 8'' on the lower protruding shaft 8b into the long hole 5' at the free end of the swinging arm 5 and moves through the long hole 5', so the swinging of the arm 5 does not cause any trouble. It moves in a straight line along the hoistway and lateral connecting path.

Of course, the gripping device 7 is not moved by the swing arm 5 as in this embodiment, but a rail is provided on the frame 3 that connects the fitting position 1a and the standby position 2a to move the traveling carriage.
The same effect can be achieved even if the gripping device 7 is provided on this traveling carriage so that it can be raised and lowered, and the gripping device is raised and lowered using a moke equipped with a brake.

As described above, the block is gripped by the gripping device 7, the gripping device 7 is lowered at the mating position 1a, and the downward facing surface of the block is accurately inserted into the plate plate stopped at the mating position 1a. To do so, the face plate must be in mating position 1.
a. Each block is positioned at a standby position or a stop position close to it.

In this embodiment, the positioning of the face plate is performed as follows.

The moving device 1 includes a guide plate 1 made of a pair of angle members arranged at a distance in the center and on which a face plate A is placed across.
2a, 12a, and an endless chain 12 whose upper band is stretched along the interval between the drawing boards and which is driven intermittently at a constant pitch.
b, and a backing plate 12c that is attached to the endless chain at intervals of the drive pitch and pushes the face plate placed on the guide plate from behind.
It consists of a group of

The longitudinal center of the face plate pushed to the fitting position 1a by the rear pushing plate 12c is always slightly behind the longitudinal center when the gripping device grasps and lowers the positioned block.

For this reason, at the rear and lower part of the mating position, a series of shafts 13' are used to attach a claw plate 13, which is normally inclined and retracted from the outer surface of each guide plate 12a so as not to obstruct the movement of the face plate on the guide plate. When the face plate is pivoted and stopped at the mating position, the piston 14 is used to raise the claw plate 13, and the claw plate 13 pushes forward the rear edge of the face plate that protrudes from both sides of the guiding plate, and the plate is moved forward and backward. After positioning, the nail plate can be retracted again.

Further, there is a fixed regulating plate 14a on the side of the fitting position facing the front end of the second transfer device 2 for transferring the block, and a push plate 14b attached to the piston 14' on the opposite side. It is pushed through the gap between both plates 14a and 14b and reaches the fitting position.

Therefore, as described above, after the longitudinal positioning by the claw plate 13 is completed, the push plate 14b presses the face plate against the regulating plate 14a by the operation of the piston 14', thereby positioning in the width direction.

In addition, when pushing with the piston 11 to release the side surface of the fitted block from the inner surface of the fixed jaw of the gripping device, the piston 1
Either the middle of the regulating plate 14a is opened so that the piston 1 can push the block, or the pushing plate 11' attached to the tip of the piston is made to push the block above the regulating plate 14a.

Of the positioning of the block, the positioning in the front-rear direction (width direction for the face plate) is performed as described above with both jaws 7a of the gripping device.
, 7b can be done by grasping the block.

The second transport device consists in this embodiment of an endless double-row chain conveyor is, is, whose upper band moves over the upper edge of the support plate, on which the blocks are advanced towards the waiting position 2a.

Then, the front end is received by a stopper 15' that crosses over both chain conveyors 15, 15, and it slips and stops at the standby position 2a.

At this standby position, in order to position the block in the width direction of the second transfer device, a regulating plate 16a and a piston-operated push plate 16b facing each other, similar to those at the fitting position, are arranged, and the block stopped at the standby position. is the push plate 1 on the chain conveyor.
6b against the regulating plate 16a and positioned in the width direction (in the front-rear direction with respect to the face plate), and then gripped by a clamping device.

In this way, the block that has come to the standby position can be correctly fitted into the face plate that is at the fitting position.

Further, it is preferable that the surface of the block to be fitted into the face plate be provided with sufficient moisture so that it blends in with the decorative material a in the face plate.

For this reason, a water receiving box 17 is provided below the transfer device 2 in front of the standby position, and when the block moves at low speed on top of the water receiving box with the surface facing downward, the nozzle 17a sprays water upward. It is designed to do so.

In this embodiment, the nozzle 17a is reciprocated by a piston 17' to spray water as the block passes over it, but of course the nozzle may also be of a fixed arrangement.

Furthermore, as shown in Figure 1, the block has two faces facing each other that can serve as the front surface, and when these faces are erected and unloaded onto the transfer device by the loading machine, the front end Another auxiliary transfer device 2' for loading and unloading is placed in front of the transfer device with the standby position 2a, and blocks are sequentially placed between the two transfer devices 2, 2' from the front end of the transfer device 2'. It is sufficient to provide a rotating type relay device 18 that rotates approximately 90 degrees when placed on the sheet and places the sheet between the chain conveyors of the transfer device 2 with one of the possible surfaces facing downward.

In this embodiment, the block transfer device 2 is arranged at right angles to the face plate transfer device 1 so as to form a T-shape, but both transfer devices 1 and 2 are arranged in parallel, and the mating position 1a and the standby position 2a may be arranged adjacent to each other in parallel.
