Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention automatically engages the protrusions containing tablets of a blister pack sheet with each other.
This relates to a device that allows continuous stacking on the same conveyance line.

[Conventional technology]

Blister pack sheets, which are used for packaging medicines, especially tablets, have a synthetic resin sheet that forms a depression at the location where the tablet is stored.The tablet is placed in the depression and sealed with thin aluminum foil to maintain airtightness. It has become very convenient to use. This blister pack sheet is made up of a predetermined number of tablets, and a plurality of sheets are stacked on top of each other, wrapped or tied with a band, packed in a box, etc., and then shipped.

[Problem to be solved by the invention]

However, since the stacking of blister pack sheets is carried out by aligning each sheet in the same direction, the stacking height is high and bulky, making transportation and storage time-consuming. In order to prevent this, the protruding parts of the blister pack sheets are made into a set of two with the protruding parts facing each other and interlocking with each other, and these are stacked in multiple stages to reduce the bulk as much as possible. When performing this stacking, each blister pack sheet is stacked one by one with its longitudinal direction aligned with the conveying direction, and reversed one by one. Since the protrusions interlock with each other, there is a drawback that the conveyance line becomes long.

In view of this, an object of the present invention is to perform interlocking stacking of blister pack sheets that are transported in the lateral direction on the same transport line.

[Means to solve the problem]

The present invention has been made to achieve the above object, and includes a conveying device A that conveys blister pack sheets in which a plurality of tablets are sealed one by one in a horizontal direction at a fixed pitch, and a conveying device A that conveys a blister pack sheet in which a plurality of tablets are sealed one by one at a fixed pitch. An interlocking stacking device C which is arranged on the same line with a conveying device B which inverts one of the sheets so that they mesh and sends out two stacked sheets, and is arranged between both the conveying devices and on the same line. , a rotary casing 4 is intermittently supported on the main body frame via a shaft 2 and is rotatably supported in the conveying direction of the blister pack sheet, and a suction cup 7 is provided at each tip on the outer surface of the rotating casing 4, and a plurality of arms are arranged at equal angles. 5a, 5
b, 6a, and 6b are provided protrudingly on the outer periphery of the rotating casing so as to rotate on the same rotation locus, and this arm is attached to the casing 4 so as to rotate the blister pack sheet 180 degrees and transfer it to the other conveying device.
Bevel gears 13 and 10 having the same number of teeth are fixed to the inner ends of the rotating casings of the shaft 11 and the shaft 2, respectively, and the bevel gears are meshed with each other. The transfer arm and the other arm are fixedly protruded from the casing to form a reversing arm that inverts and transports the blister pack sheet 180 degrees, and these are arranged alternately, so that the tip of each arm is located at the end position of each transport device.

〔Example〕

The present invention will be explained below based on the illustrated embodiments. In the figure, A is a conveying device that conveys blister pack sheets S in which a plurality of tablets are sealed one by one at regular pitches in the lateral direction. This is a conveying device in which one side is reversed to send out two stacked sheets, and both of these conveying devices A and B are arranged on the same line, and between these two devices, the interlocking stacking of the present invention is carried out. Device C is placed;
Make sure that A, C, and B are on the same line.
Since the conveyance devices A and B are similar to conventional conveyance means, detailed explanation thereof is omitted, but it is desirable that the conveyance device A has twice the conveyance capacity of B; It is not limited.

As shown in detail in the drawings, the meshing stacking device C of the present invention has a rotating casing 4 rotatably supported via a bearing 3 on a shaft 2 supported by a bearing 1 fixed to a main body frame, etc. Arms 5a, 5b, 6a, 6b each having two or four suction cups 7 are arranged at equal intervals on the outer surface of the casing 4 and protrude in the radial direction. More specifically, a cylindrical support part 4a is integrally provided on one side or both sides of the rotating casing 4, and a shaft 2 fixed to a bearing 1 passes through the support part 4a, and the rotating casing is supported by a bearing 3. is rotatably supported, and a gear 9 (or sprocket) is attached to the outer periphery of the support part.
The drive gear 9 (or sprocket wheel, chain) is meshed with this to provide intermittent rotation according to the number of arms protruding from the outside of the rotating casing, i.e. 90 degrees for four arms as shown in the figure, and 90 degrees for two arms as shown. For example, intermittent rotation of 180 degrees is performed in accordance with the conveyance direction of the blister pack sheet, and a bevel gear 10 is fixed to the end of the shaft 2 inside the rotating casing. On the outer surface of the rotating casing 4, shafts 11, 11 are rotatably supported in a direction orthogonal to the shaft 2 by bearings 12 fixed to the casing, respectively.
A bevel gear 13 is fixed to the inner end of the casing, and both bevel gears 11 and 13 have the same number of teeth.
Arms 5a and 5b are arranged to mesh with each other, and arms 5a and 5b are provided on the outer end side of each shaft 11 to protrude in the radial direction of the casing.
Arms 6a and 6b are fixed to the outside of the rotating casing and protrude in a direction perpendicular to b, and the arms 5a,
5b, 6a, and 6b rotate on the same locus when the rotating casing rotates. In this case, if there are four arms, arms 5a and 5b and 6a and 6
b are assumed to be facing each other in a straight line, but 180
Only two arms 5a and 6a rotate intermittently and are arranged facing each other in a straight line.For example, in FIG.
It is sufficient to replace the arm 6a with no other arm by omitting the other arm. Also, each arm 5a, 5b, 6a, 6
One or two suction cups 7 are provided at the tip of b, and the orientation of each suction cup 7 is such that the rotation direction of the arm is the front surface, that is, the suction surface, and the air hose H is connected from inside the shaft 2 through the rotating casing. The blister pack sheet is connected to each suction cup through the holder, and by suctioning from the end of the shaft 2, all the suction cups suction the blister pack sheet at the end of the conveying device A, and transfer it to the conveying device B side as necessary. Although the suction is released, it is not necessary to release the suction on the conveyance device B side.

In addition, the embodiment of the drawings shows a case where the blister pack sheets are conveyed in a row in the horizontal direction, but
When conveying multiple rows in parallel, the interlocking stacking device of the present invention is provided for each conveyance line, and in this case, in order to simplify the power transmission mechanism etc., adjacent rotating casings are connected and supported with each other. It may also be changed depending on the size of the blister pack sheet, and the design may be changed as appropriate depending on the embodiment.

The operation of interlocking and stacking blister pack sheets conveyed in the apparatus constructed as described above will be explained.

As shown in Figure 1A, the conveyor A
At the terminal end of the device A, the blister pack sheet S being conveyed above is suctioned by the suction plate of the arm 5a on the flat side of the bottom surface of the sheet. This is because the arm is driven intermittently so that the direction of rotation is from the back side to the front side of the blister pack sheet, so that the rotating casing with the arm projecting from it is stopped at this blister pack sheet suction position. Therefore, the suction cup can reliably suction the blister pack sheet. Next, when the casing is rotated, the arm 5a is rotated in the vertical direction, that is, around the shaft 2, from the horizontal state at the transport device A position. When the arm 5a revolves 90 degrees, the bevel gear 13 fixed to the arm 5a via the shaft 11 is meshed with the bevel gear 10 fixed to the shaft 1, and both gear ratios are the same, 1:1. Therefore, it also rotates 90 degrees around axis 11. As a result, the blister pack sheet suctioned by the suction cup 7 of the arm 5a is supported vertically and elongated in the conveying direction. Due to this 90 degree revolution of the arm, the arm 5a is in a vertical state and is at an intermediate position between the transport devices A and B, and the other arm 6a is in a stopped state at the transport device A position.
The next blister pack sheet is sucked by the suction cup of the arm 6a. When the rotating casing further rotates, the arm 5a revolves from the vertical state and moves toward the conveying device B side, and becomes horizontal. At this time arm 5
The next blister pack sheet is sucked at the transport device A position, and the arm 6a operates in the same manner as the arm 5a due to the rotation of the casing, and the arm 6a is in the vertically upper position and the arm 6b is in the vertically lower position. When the arm 5a moves from the vertical state to the horizontal state of the conveying device B, the arm 5a moves to the axis 1 due to the action of the bevel gear.
1 further rotates in the same direction by 90 degrees, and as a result, the blister pack sheet turns 180 degrees, and due to the revolution, the blister pack sheet, which was long and vertical in the transport direction, returns to its original horizontal state. , the blister pack sheet is not reversed, but merely rotated 180 degrees so that the surface of the sheet faces upward and is transferred from conveyor A to B.
In this state, the blister pack sheet is stopped on the conveying device B. Next, as the rotating casing rotates, the next blister pack sheet is attracted by the arm 6a, and since the arm 6a is fixed to the rotating casing, the direction is the same, but it is reversed 180 degrees, that is, turned inside out. When stacked on a blister pack sheet, the protruding parts of each sheet will face each other, but since the longitudinal directions of the sheets are different from each other (one sheet rotates 180 degrees).
The protrusions are stacked one on top of the other so as to mesh without colliding with each other. After the two sheets are stacked in this way, they are transferred on the conveying device B, and in this way, two different types of arms, ie, arms 5a and 5b, rotate the blister pack sheet 180 degrees, and arms 6a and 6b rotate the blister pack sheet. By alternately performing the reversal of each of the two, desired interlocking and intussusception can be continuously and automatically performed on the same line. In the case of the two-arm type, the same procedure is performed, but in order to obtain the same stacking capacity, the rotation speed should be twice that of the four-arm type.

〔Effect of the invention〕

According to the present invention, the blister pack sheets transported horizontally on the transport line are alternately rotated 180 degrees on one side and reversed on the other, so that the protruding parts are stacked so that they interlock with each other.
Since this interlocking stacking can be carried out using the same device and the same line while the blister pack sheet is being fed horizontally, the stacking conveyance line can be made shorter than before, making it possible to use it effectively even in small factories, and also allowing interlocking stacking. It has the advantage that multiplication can be performed accurately and at high speed.
