Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a conveyor system used in a bottling line for beer, etc., and is installed upstream of a filling machine, etc., and impacts the supply of containers such as bottles to be conveyed. The present invention relates to a container supply stopping device used when removing and stopping.

[0002]

2. Description of the Related Art In this type of conveyor system such as a bottling line, due to insufficient supply of materials such as crowns, time to replace labels, troubles in downstream processes, etc. It may be necessary to stop the supply. In such a case, there is a method of inserting a stopper member between the containers on the basis of the stop command signal to stop the supply of the containers. It caused a trouble such as noise and overturning of the container, sometimes causing a bottle breakage and the like. To deal with this, it is possible to gradually reduce the conveyor speed and stop it, but as with beer filling,
One that includes steps with certain processing conditions, such as bubbling the empty space to remove oxygen before filling and capping.For example, the air on the upper surface of the beer liquid is water. Remove by blowing and lathering
Since it was necessary to prevent the timing of the jet former from shifting, the filling machine could not be slowed down, and the container had to be stopped suddenly while moving and filling at high speed. As a solution to this problem, the guide shaft and the air cylinder for table deceleration stop are mounted on the mounting base, and the mounting base is arranged at the side position of the bottle conveyor, and the star stopper for the bottle stopper and the air for stopping the star wheel are installed. The bottle stopping device of the bottle feeding device, which attaches the cylinder to the table, supports the table movably in the feeding direction of the bottle conveyor by the guide shaft, and connects the table to the table deceleration stop air cylinder, It is known (see Japanese Patent Laid-Open No. 2-138015).

[0003]

However, in the above-mentioned prior art, first, the stopper star wheel is instantaneously stopped, and the bottle that is in the stopper star wheel and the bottle that exists upstream thereof. By pressing
The stopper star wheel starts moving from the standby position to the stop position, but resistance is momentarily added to the bottle on the upstream side where the stopper star wheel has stopped, and the impact and the collision noise of the bottle comrades generated at that time. There was a problem that was inevitable. Moreover, when the container is stopped, the movement from the standby position to the stop position is due to the pressing of the container, and the cylinder merely serves as a brake. Therefore, it is not possible to control the movement of the container from the standby position to the stop position. Since the movement starts after pushing out the stopper star wheel, there was a problem that there was an impact at first. Even if a claw-type stopper is used instead of the stopper star wheel, there are similar problems. In view of this situation, the present invention eliminates the above-mentioned drawbacks of the prior art,
By inputting the container stop signal, first, the deceleration pressing device, for example, the movable stopper device via the deceleration cylinder moves from the standby position to the stop position at a speed substantially equal to or higher than the container flow speed. Start moving. Then, during the movement, the movement is detected by the detector, and the stopper cylinder is actuated by the input of this detection signal, and the stopper member comes out. After that, it is an object of the present invention to provide a container supply stopping device in which the moving speed of the deceleration cylinder itself is reduced and the stopping speed is almost reached to zero.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and in a container supply stopping device, the container is inserted between the containers to be conveyed on the container-conveying conveyor, and the container-conveying conveyor. A movable stopper device having a stopper member that gradually stops the container while moving along the transport direction of the container, and a pressing slide control device that controls the stopper member and the movable stopper device by a signal from a detector. The technical means of having

[0005]

According to the present invention, by adopting the above technical means, the stopper member is taken out and stopped while moving at substantially the same speed as the flow of the container. Moreover, at first, it moves at high pressure and quickly,
Since the pressure is gradually reduced as the pressure is gradually reduced, the container on the upstream side is not shocked at the moment the supply of the container is stopped, and the collision noise between the containers is not generated. Moreover, the transfer state of the container is not made unstable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a schematic plan view of a specific example. The container 1 that has been washed and sterilized is conveyed by the container conveying conveyor 2 and is transferred to a filling machine (not shown) via the timing screw 3. A movable stopper device 4 is provided in parallel with the container transporting conveyor 2, and a deceleration cylinder 5 for sliding the movable stopper device 4 itself is provided at one end. Moreover,
Stopper cylinder 7 for moving the stopper member 6 forward and backward
Are provided on the mounting base 8 of the movable stopper device 4. The movable stopper device 4 slides back and forth through the guide rod 9 by the action of air pressure on the deceleration cylinder 5. It caused some trouble,
When the supply of the container 1 has to be stopped, the first detector 10 that detects the movement of the movable stopper device 4 and the movable stopper device 4 are stopped at the stop position 23.
The second detector 11 for detecting the arrival at the position is provided at an appropriate portion of the deceleration cylinder 5 or the movable stopper device 4. Further, a third detector 12 for detecting that the stopper member 6 is retracted by the stopper release signal is provided. A pressure sliding control device 13 for performing switching control based on the detection of each of these detectors 10, 11, 12.
Is provided. The pressing / sliding control device 13 controls the reciprocating sliding of the deceleration cylinder 5 and the stopper cylinder 7. This pressure sliding control device 13
1, the air source 14 is branched into two directions of the deceleration cylinder 5 and the stopper cylinder 7 via the regulator 15 so that the air can be switched and sent to the front and rear ends of the piston of the deceleration cylinder 5. As described above, the first speed control valve 16 and the first and second switching solenoid valves 1
The air sources 14 are connected to the air sources 7 and 18 and the cushion tank 19, respectively. Further, a third switching solenoid valve 20 for switching and operating the stopper cylinder 7 is connected so that air can be switched and sent to the front and rear ends of the piston of the stopper cylinder 7.

Next, the operation will be described with reference to FIGS. First of all, in brief explanation, when stopping the container,
When moving from the standby position to the stop position, a signal is input and the movement is started. Therefore, the stopper member projects during the movement. Since the moving speed is controlled by the deceleration cylinder, the moving speed is high at the beginning and gradually decreases to reduce the impact. This will be described in more detail over time. When the stopper member 6 is normally operated with the retracted state, the air of the air source 14 at this time is
Via the regulators 15 and 15, to the third switching solenoid valve 20 on the stopper cylinder 7 side, and on the deceleration cylinder 5 side, from the first speed control valve 16 to the cushion tank 19 and the first switching solenoid valve 17, , The second speed control valve 21 to the second switching solenoid valve 18 are filled. At this time, the portion of the stopper cylinder 7 is located at the standby position 22 (see the one shown by the dotted line in FIG. 1). Then, when a machine stop signal is input, the first switching solenoid valve 17 is first opened to operate the deceleration cylinder 5. This operation is a sliding action, and since a high pressure acts at the moment of opening, at the beginning, it is almost the same as the flow velocity of the container 1 or higher than that, from the standby position 22 to the stop position 23. Start moving in the direction of (see what is indicated by the dotted line in FIG. 2). The movement is detected by the first detector 10 and the third switching solenoid valve 2
0 is opened, or a timer is provided which transmits a signal after a certain set time has elapsed since the first switching solenoid valve 17 was opened, and the signal of this timer is received to open the third switching solenoid valve 20. By setting the timing, the stopper cylinder 7 operates and the stopper member 6 comes out.
Further, instead of the first detector 10 for detecting the movement, the above-mentioned operation can be achieved even if a detector is provided at an appropriate portion of the movement process of the movable stopper device 4. Then, after that, since the air supply amount to the cushion tank 19 is throttled by the first speed control valve 16 so that the air pressure decreases as the deceleration cylinder 5 itself moves, the moving speed decreases and the speed is almost zero. The stop position 23 is reached at a speed close to (see the dotted line in FIG. 3). Next, when the second detector 11 detects that the stop position 23 has been reached, the first switching solenoid valve 17 closes, and the pressure in the cushion tank 19 is increased again. In this state, the stopper member 6 is still protruding (see the one shown by the dotted line in FIG. 4). Then, when the signal for eliminating the trouble and notifying that the machine has started to move is input, the third switching solenoid valve 20 switches so as to retract the stopper member 6 (see the one shown by the dotted line in FIG. 5). As a result, when the third detector 12 detects that the stopper member 6 has retracted according to the instruction of the stopper release signal, the second switching solenoid valve 18 is opened and the deceleration cylinder 5 is returned to the standby position 22 (see the dotted line in FIG. 6). See the one shown in). However, it goes without saying that the softening is taken into consideration so that the piston of the deceleration cylinder 5 passes through the portion of the first detector 10 at this time, but the stopper member 6 does not project. In this embodiment, the cushion tank 19
I explained the one that adopted the first speed control valve 1 without the cushion tank 19.
6. The same effect can be obtained by automatically changing the flow rate of the second speed control valve 21. 7 and 8 are a plan view and a side view in which only the movable stopper device 4 is taken out. The mounting base 8 on which the stopper member 6 and the stopper cylinder 7 are mounted slides left and right with the guide rod 9 as a guide by the reciprocating motion of the deceleration cylinder 5. Needless to say, the reciprocating motion can be converted into a rotating motion so that the screw shaft can slide on the guide. Further, as the movable stopper device 4, a stopper cylinder 7 is used to project the stopper member 6, but the invention is not limited to this, and instead of the illustrated stopper member,
It goes without saying that the stopper star wheel of the prior art may be used.

[0008]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) Since the container on the upstream side is not shocked at the moment when the stopper member comes out, the collision noise between the containers does not occur and the transfer state of the container does not become unstable.
