Abstract

PURPOSE:To enable a bottle to be distributed by a simplified device, by movably providing the outlet end side of a bottle guide along the parallelly arranged direction of straightening lanes, when the bottle from a supply conveyer in every predetermined quantity is distributed to a plurality of the parallelly arranged bottle-straightening lanes in a receiving conveyer. CONSTITUTION:A bottle is carried into predetermined one of the bottle-straightening lanes 4... from a supply conveyer 2 via a bottle guide 1, and if the bottle numbers reaching a predetermined quantity being detected by a suitable detecting means, an advance of the bottle in the guide 1 is restricted by transversely actuating a stopper 19 through an air cylinder 20 so as to press the bottle from the sideward. While a movable block 8 is transversely actuated by simultaneously turning a feed thread 11 by a motor 10, turning the bottle guide 1 to a side of the straightening lane 4 in the next position to be aligned with said lane 4. Then the bottle is started to be carried toward the straightening lane 4 in the next position by resetting the stopper 19 to a release position. Thereafter, the bottle is continued to be distributed by repeating the similar action.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic bottle distributing device, and more particularly, to an automatic bottle distributing device, which takes bottles from a supply conveyor and distributes them to a predetermined number of bottles to a plurality of parallel bottle alignment lanes of a receiving conveyor by sequentially shifting between these lanes. The present invention relates to an automatic bottle dispensing device of the type that utilizes a bottle guide.

In such an automatic bottle distribution device, in order to distribute the required number of bottles to multiple parallel bottle alignment lanes on the receiving conveyor in a smooth flow, it is necessary to accurately shift the bottle guide for each bottle alignment lane. must be carried out.

Conventionally, in this type of automatic bottle distribution device, the shift of the bottle guide for each hinge alignment lane is performed by rotating the bottle guide at a fixed angle about a fixed point on the starting end side of the bottle guide, in other words, on the end side of the bottle guide on the supply conveyor side. According to this method, the end side of the bottle guide performs a circular motion with respect to the parallel straight lines of a plurality of parallel bottle alignment lanes, so that the relative position of the end of the bottle guide with respect to the bottle alignment lane is aligned with the bottle at the end. As you line up in your lane, it is inevitable that you will gradually drift off. Despite this, conventional bottle guide shifts have been relied on in this way because the bottles that are automatically distributed are mainly cylindrical, and the end of the bottle guide is slightly positioned in relation to the bottle alignment lane. This is based on the fact that even if the bottles are misaligned, they will be fed by conveyor without getting caught in the receiving lane. However, there are also bottles with square or other shapes that are not round (hereinafter referred to as irregularly shaped bottles). In the case of irregularly shaped bottles, if the bottle is not correctly centered in the bottle alignment lane by the bottle guide, it will not be fed properly into the bottle alignment lane and will get stuck at the lane entrance, causing a stagnation in the flow of bottles conveyed by the conveyor, and the bottle A PL bottle with an incorrect distribution number may fall over, making distribution impossible.

In conventional shifts of the bottle guide, which revolves around a fixed point, the turning angle of the bottle guide must be gradually corrected for each shift in order to correctly align the end of the bottle guide with each bottle alignment lane. First, shift control of the bottle guide becomes complicated.

The present invention eliminates the drawbacks of the prior art described above, allows the bottle guide end to face each of a plurality of parallel bottle alignment lanes of a receiving conveyor sequentially and without displacement, and does this simply. The purpose of this invention is to provide an automatic bottle dispensing device that ensures the following.

The automatic bottle distributing device of the present invention is rotationally displaced sequentially from one lane to another so as to distribute and guide bottles from a supply conveyor to the required ones of a plurality of parallel bottle alignment lanes of a receiving conveyor. a bottle guide, when the number of bottles carried from the supply conveyor to the bottle alignment lane via the guide reaches a predetermined number, the bottle guide moves straight along the parallel direction of the bottle alignment lane, moves a predetermined distance, and then stops; A first movable block and a second movable block capable of linear movement along the length of the bottle alignment lane are placed in fixed positions, and the end side of the bottle guide is attached to the first movable block. The bottle guide is characterized in that the starting end side is pivotally connected to the second movable block so that the bottle guide can perform the above-mentioned rotational displacement.

According to the present invention, when the number of bottles carried from the supply conveyor to the bottle alignment lane via the bottle guide reaches a predetermined number, the first movable block is moved straight along the parallel direction of the bottle alignment lane of the receiving conveyor, It is moved a predetermined distance, ie, to a position corresponding to the next bottle alignment lane, and then stopped. The movement of the first movable block is controlled by a suitable method, for example, by counting the bottles being carried out from the bottle guide using a counter known per se, and when the count reaches a predetermined number, the actuator of the first movable block is activated. is driven to move the movable block in a predetermined direction, and while it is moving, the movement is electrically or electronically quantized (generally, it can be converted into pulses), This can be done by transmitting a signal from a transmitter to a counter and stopping the actuator of the first movable block based on the predetermined count.

Due to the above movement of the first movable block, the bottle guide whose distal end is pivotally connected to the movable block moves so that its distal end reaches #! 1
The next bottle is aligned with the movable block and rotated to a position directly facing the bottle. In this case, since the second movable preset bottle alignment lane, to which the starting end of the bottle guide is pivotally connected, can move linearly along the length of the bottle alignment lane, the entire bottle guide moves toward the distal end as the distal end moves linearly. It moves and rotates to smoothly perform the required shifts.

Thereafter, in the same manner, each time the number of imported bottles in the bottle alignment lane reaches a predetermined number, the bottle guide is sequentially shifted to a position corresponding to the next bottle alignment lane. In this way, according to the present invention, the end of the bottle is Since the bottle guide can be shifted to a position corresponding to the next bottle alignment lane by moving the alignment lane straight ahead along the parallel direction, the indicated linear movement amount of the first movable block can be set to a predetermined value υ by appropriate means. By doing so, the end of the bottle guide can be successively faced to each of the plurality of parallel bottle alignment lanes on the receiving conveyor without any positional deviation, and this can be done more simply than in the past. Guaranteed.

The second movable block (a) is slidable on a guide rod extending along the length of the bottle alignment lane (4).

The bottle alignment lane (4) has guide fences Q4 located in position extending along the length of the receiving conveyor (3) at opposing spacings corresponding to the diameter of the bottles.

The bottle guide (1) communicates the bottle alignment lane (4) with the guide lane (5) of the supply conveyor (2).

Bottle guide (1) #:i: Attach the front and rear ends to the above pin (6),
(9) extends from the second movable block (2) from 4C to the upper par connected to the first movable block (8)) along the longitudinal direction of the bottle alignment lane (4), preferably at least one of the .

◎The bottle guide (1) also has a stopper α on the end side that presses and restrains the bottles in the bottle guide (1) from the side.
Have time. (1) is an air cylinder plunger device for operating the stopper.

When the stopper α is set, the end of the bottle guide (1) is in the position where the bottles in the bottle guide (1) are not restrained, that is, the release position, with the end of the bottle guide (1) directly facing the bottle alignment lane (4) comprising the receiving conveyor (3). brought about.

With the stopper (6) in the released state, the bottles are carried from the supply conveyor (2) through the bottle guide (1) to the bottle alignment lane (4) ◎The bottles carried out from this bottle guide (1) suitable detection means placed in place;
For example, it is detected by a photoelectric switch, which sends a signal to the counter, which counts it. When the above count reaches a predetermined number, the stopper Q is activated by the air cylinder plunger device (E).
Bottles in the bottle guide (1) are pressed from the side and restrained◇Therefore, the conveyance of bottles to the bottle alignment lane (4) is stopped.

On the other hand, at this time, the feed screw Oυ is driven by the motor Ql, and the first movable block (8) or bottle alignment lane (
4) The bottle guide (1) is moved straight along the parallel direction, and the bottle guide (1) is rotated toward the next bottle alignment lane (4). ``When the end of the bottle guide (1) shifts with the first movable block (8) and comes to directly face the next bottle alignment lane (4), the feed screw (B) is stopped and the 1's movable block (8) and bottle guide (1) are also stopped. ◎Next, the stopper α is brought to the release position again, and the bottles are carried into the next bottle alignment lane (4). Ru.

This control over the shift of the bottle guide (1) is performed by electrically controlling the movement of the first movable block (8) or a part interlocked therewith, for example, during the shift of the bottle guide (1). or electronically quantize, e.g. convert into pulses,
This is transmitted to a counter and counted, and the count reaches a predetermined value. That is, when the bottle guide (1) is displaced to a position directly facing the end bottle alignment lane (4), the movable block (
This can be done by stopping the drive system in 8) ◇ By applying such a pulse counter, the bottle guide (
When performing the shift control in 1), it is preferable to determine the origin position and correct the counting origin of the pulse counter based on the origin position in order to ensure the accuracy of the shift control.

Appropriate means for this, such as bottle alignment lane (4)...
a light-shielding plate (2) arranged at a fixed position extending from a position corresponding to the center line of the parallel body to one side end, and a photoelectric switch mounted at a fixed position on the first movable block (8)). What is included as a component can be applied. This shift control is performed by subtracting the number of pulses for the travel distance corresponding to the luminous flux width of the photoelectric switch from A1 to the number of pulses for the regular travel distance between the bottle alignment lanes, and B1 Assuming that the number of pulses for the regular moving distance is C, the pulse counter that counts pulses with pulse number B is FB, and the pulse counter that counts pulses with pulse number c is Pc, the bottle alignment lane (4)... When the number of parallels is even, the following is true: ◇ After the photoelectric switch (2) moves towards the first movable block (8) and passes the right end of the light-shielding plate in Fig. 8, that is, the origin position,
When moving in the direction opposite to 6!]), it moves by the number of pulses A until light enters the photoelectric switch, and when it moves A, the photoelectric switch When the pulse counter pB starts counting pulses in response to the light incident signal of (
4) is completed, and the drive system of the first movable block (8) is stopped by an external signal. ◇When the shift is started again by another external signal, the pulse counter PC starts counting at the same time. , when it counts up, the first movable block (
8) The drive system stops. Below is the pulse counter PC
Repeat shift control. Then, the shift is reversed from the outermost bottle alignment lane, and after moving to the nearest bottle alignment lane to the above origin position, the counting origin of the pulse counter is corrected by the light-blocking signal of )' on the photoelectric switch, that is, the origin When shifted a distance equivalent to the number of pulses A from the position, the pulse counter FB counts and shifts to the next bottle alignment lane, and the next shift is performed using the pulse counter PC.
control based on the count.

If the number of parallel bottle alignment lanes (4)... is odd,
The origin position is on the center line of the centrally arranged lane, and the shift between the bottle alignment lanes adjacent to the left and right with this origin position in between is from the number of pulses C- of the normal movement distance to the number of pulses A.
It is sufficient to set the number of pulses by subtracting the number of pulses, and set the number of pulses C for shifts between other bottle alignment lanes.

The bottle guide (1) reciprocates and rotates to align each bottle (4
)... When the bottles are distributed and guided, the outermost bottle alignment lane becomes the turning point for the reciprocating rotation of the bottle guide (1), and the bottle alignment lanes other than the outermost bottle alignment lane are Since the number of opportunities to encounter the bottle guide (1) is reduced, in order to ensure that the number of bottles allocated to each lane is the same, the bottle alignment lanes are arranged next to the outermost bottle alignment lane, which is the turning point. The point of shift to is determined. That is, for example, if the number of bottles allocated to each bottle alignment lane (4) is 5 by guiding the bottle guide (1) - times, then
When 10 bottles are carried into the outermost bottle alignment lane, which is the turning point, a shift is made to the next lane, and when the number of bottles carried in at the bottle alignment lane other than the turning point is counted as 5. , a shift is made to the next lane.

In this way, the bottle guide (1) is connected to the bottle alignment lane (4).
) Each time a predetermined number of bottles are carried into the bottle guide (1), they are shifted from the bottle alignment lane that had been facing each other to the next bottle alignment lane, and the position is changed so that the next lane and the end of the bottle guide (1) are directly facing each other. The vehicle will be stopped at the bottle and bottle alignment lane (4).
) will be distributed to a predetermined number of recipients.
