Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to, for example, in a washing machine, a conveying device for smoothly delivering a bottle to be washed transferred from a pretreatment step by a conveyor to the washing machine. In particular, the present invention relates to a fallen bottle removing device provided in this carrying device.

[Conventional technology]

In order to supply bottles to the washing machine, a set of aligned bottles that are usually fed on multiple rows of conveyors are passed through a delivery mechanism at the end of the conveyor, and bottles are installed on the processing conveyor of the washing machine. It is designed to be dropped into the holder one after another.

However, when such a bottle transfer device for a bottle washing machine causes a bottle to fall on the conveyor, the bottle delivery mechanism described above cannot function normally. Therefore, in the past, an inversion bottle detector was installed on the conveyor to detect an inversion bottle in an upright bottle, and an alarm was generated.Each time, the operation of the device was stopped and the inversion bottle was manually removed. I was trying to do the work.

Therefore, in order to solve these problems, a gap is provided between the end position of the conveyor and the delivery mechanism, and a hanging guide rail is extended from the vicinity of the end position of the conveyor to the delivery mechanism. At the same time, the upright bottle has already proposed a tipping bottle removing device that discharges only the bottle laterally from the above gap and guides the protruding part of the outer circumference of the wide mouth to this guide rail to deliver it to the delivery mechanism. (Japanese Patent Publication No. 42-14672).

[Problems to be Solved by the Invention]

As described above, in the conventional transfer device, the above-described bottle removing device can be applied to a bottle having a large opening diameter such as a wide-mouthed bottle by the guide rail, but a guide rail can be used for a bottle having a small opening diameter. However, there is a problem in that the machine is still stopped each time a fallen bottle is detected, and the removal work has to be performed manually, which lowers the operation rate.

The present invention has been made to eliminate the above-mentioned drawbacks, and automatically and reliably sorts and removes the bottles contained in the upright bottles in the conveying process, and only the bottles in the upright state are washed by a bottle washing machine or the like. It is an object of the present invention to provide a bottle-removing device that can be delivered to a bottle processing mechanism.

[Means for Solving the Problems]

The bottle removing device according to the present invention is provided with a plurality of rows of conveyer conveyors for feeding bottles to the bottle processing apparatus, the bottle detecting means for detecting the presence or absence of bottles in each row of the conveyor, and this bottle The inclining bottle removing mechanism is provided on the downstream side of the detecting means and is biased based on the detection signal from the inclining bottle detecting means to hold and discharge the inclining bottle. An operating unit main body provided so as to be capable of reciprocating across it,
It is characterized in that it comprises an inverting bottle holding means which is provided on the operating unit main body so as to be able to move up and down and holds the inverting bottle.

[Action]

According to the inversion bottle removing device of the present invention, the inversion bottle on the transport conveyor is detected by the inversion bottle detecting means, and the inversion bottle removing mechanism urged based on the detection signal detects the inversion bottle manually. It can be eliminated automatically without any need and reliably regardless of the type of bottle.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to illustrated embodiments. 1 to 3 are a side view, a front view and a plan view showing a falling bottle removing device according to an embodiment of the present invention, and FIGS. 4 (a) and 4 (b) are different from each other for holding bottles. It is explanatory drawing which shows the different operation mode.

As shown in these figures, the conveyor (1) that conveys a large number of bottles (c) is divided into multiple rows by the guide member (2) and has been transferred to the end of this conveyor (1). A delivery mechanism (4) for sequentially delivering the set of the arranging bottles (c) is provided. As shown in FIG. 1, at the end of the conveyor (1), a set of upright bottles (C _s ) placed on the end spout (3) of the conveyor (1) and tilted along the end of the conveyor (1) is installed in the transfer mechanism (4). It is transferred to the pick-up part (5a) by the moving pick-up arm (5), delivered to the bottle washing machine (7) side, and successively dropped into the bottle holder (7a) provided on the processing conveyor. It is like this.

However, the inverted bottle detector (10) constituting the inverted bottle detecting means is provided facing the conveyor (1). As shown in FIG. 1, the falling bottle detector (10) is provided with a falling bottle checker (10a) pivotally supported on the falling bottle detector (10) and its contacts (10b) for each row of the conveyor (1). Further, according to the inversion bottle detector (10), the upright bottle (C _s ) has the checker (1
0a) is supported by contacting the hanging lower end with the checker (10a).
(10b) is held in a non-contact state, but when the falling bottle (C _d ) arrives, the checker (10a), which cannot be supported from below by the rim of the bottle, rotates clockwise in Fig. 1. Move to contact (10
Upon contact with b), the detection signal of the falling bottle (C _d ) is sent to the control device (11). Upon receipt of this detection signal, the control device (11) urges the device drive motor (12) to move the inversion bottle (C _d ) by a predetermined distance, and then the conveyor (1) is stopped.

Next, on the downstream side of this fall bottle detector (10), the delivery mechanism
An inverted bottle removing mechanism (20) is provided immediately in front of (4).
The inversion bottle removing mechanism (20) is arranged so as to straddle the conveyor (1) and the inversion bottle discharge conveyor (6) provided on one side of the conveyor above and above the conveyor (1). As shown in Fig. 3, the motor is attached to the endless chain (24) wound around the sprocket (23a) on the one side and the sprocket (23b) on the other side driven by the motor (22), and is integrally shown. The actuator main body (25) is reciprocally provided along the guide member. Then, the actuating section main body (25), the urging bottle (C _d ) is a predetermined distance on the conveyor (1) by the urging of the control device (11) based on the detection signal of the bottle falling detector (10), that is, As shown in FIG. 1, after the bottle is sent to a position directly below the bottle removing mechanism (20) that leaves one bottle between the delivery mechanism (4) and the conveyor (1), the controller (11) is stopped. ) Urges the motor (22) to traverse with the endless chain (24). Reference numeral (21) denotes an encoder that detects the rotation of the motor (22) and feeds it back to the control device (11).

In the rear part of the lower part of the operating part body (25), as shown in FIG. 1, in particular, an inverted Y-shape is formed so as to sandwich the mouth part of the upright bottle (C _s ) on the conveyor (1). An inversion bottle position detector (27) is provided, and a detection sensor (26) including, for example, a light emitting portion and a light receiving portion, which face each other, is provided inside the Y-shaped portion. Therefore, when this fallen bottle position detector (27) moves laterally on the conveyor (1) together with the operating section body (25),
The position of the bottle on the conveyor (1) is detected by the presence / absence of a bottle that passes between the detection sensors (26). It should be noted that the above-mentioned tipping bottle detector (10) not only detects whether or not there is a tipping bottle, but also adds the function of the tipping bottle position detector (27) to detect the tipping bottle position at the same time. You may allow it.

In addition, as shown in FIG.
The tilting bottle holding means (30) is movably mounted on rails (31) provided on both sides of the long hole (25a) along the operating direction of the conveyor (1), and the piston rod (33) connected to this is held. Through cylinder
It is possible to reciprocate by (32). The inclining bottle holding means (30) is composed of an elevating cylinder (28) standing upright.
Of the gripper (2
The gripper (29) is provided with a limit switch (34). And the gripper
(29) is inserted between the bottles that are conveyed close to each other and
In order to surely hold (C _d ), it is set so as to hold a small diameter bottle part, and the lifting cylinder (28) is operated to lower it in two steps. That is, as shown in FIG. 4 (a), a predetermined first value corresponding to the bottle diameter
If the limit switch (34) is activated during step descent,
It is determined that the position of the gripper (29) is located in the body of the falling bottle (C _d ), and the falling bottle holding means (30) is moved by the cylinder (30) a required distance according to the bottle length. After that, the second stage descent is performed on condition that the limit switch (34) is de-energized and positioned at the bottle mouth as shown in Fig. (B), and the bottle (29) causes the bottle to fall ( C _d ) is gripped. Of course, it goes without saying that, from the beginning, in the state of FIG. 4 (b), the gripper (b) is continuously lowered in the second stage.

Next, the operation will be described.

The plural rows of conveyors (1) are intermittently conveyed so that a group of bottles in plural rows can be sequentially delivered in accordance with the operation of the delivery mechanism (4). Then, when the inverted bottle (C _d ) is detected by the inverted bottle detector (10) on the plural rows of conveyors (1), the drive motor is activated by the control device (11) that receives the inverted bottle detection signal.
The conveyor (1) is driven by a predetermined moving distance via the (12) and stopped, and at the same time, the transfer mechanism (4) is operated for a predetermined cycle to stop. At this time, the bottle (C
The operation of the conveyor (1) and the delivery mechanism (4) is stopped, leaving only one upright bottle (C _s ) on the downstream side of _d ).

Next, with the conveyor (1) stopped, the delivery mechanism
(4) is operated for one cycle, and the erect bottle (C _s ) on the downstream side of the bottle (C _d ) is handed over to the delivery mechanism (4) to release the bottle pressure when the bottle is discharged in advance.

In this state, as described above, the control device (11)
As a result, the motor (22) is energized, and the actuating section main body (25) is moved laterally via the chain (24). Stopped conveyor (1)
The top of the operating part body (25) and the tipping bottle position detector (27) are moved while detecting the presence or absence of the tipping bottle between the sensors (26), and the tipping bottle holding means (30) is placed at the detected tipping bottle position. Position it.

When the inclining bottle holding means (30) is positioned, as described above, the lifting cylinder (2
8) is urged to lower the gripper (29) in the first stage, and when the limit switch (34) is actuated as shown in Fig. 4 (a), the gripper (29) is turned upside down. It is determined that the bottle is the bottle body of (C _d ), the cylinder (32) is urged, and the bottle holding means (30) is moved on the rail (31) together with the gripper (29) for a required distance, so that the cylinder (32) is moved as shown in FIG. ) When it arrives, the second stage descent is performed and the bottle is crushed (C _d ).
The small-diameter mouth portion can be reliably gripped by the gripper (29). Then the fallen bottle held by the gripper (29)
(C _d ) is lifted by the lifting cylinder (28), is carried to the discharge conveyor (6) by the movement of the operating unit body (25), is released from the gripper (29), and is discharged and removed. Then, when the falling bottle removing work is completed, the carrying work by the conveyor (1) is started again.

Although the gripper (29) holds the inverted bottle (C _d ) in the above embodiment, it is obvious that other holding means such as a vacuum pad can be used.
