Abstract

PURPOSE:To prevent damages of a PTP sheet by supporting stacked PTP (Press Through Packing) sheets with a support to always keep a fixed interval with the following PTP sheet to be stacked. CONSTITUTION:A hopper 9 is disposed above a conveyer 1 for conveying a PTP sheet S and a stacking plate 6 adapted to move up and down in response to an operation signal is disposed below the hopper 9. A stopper 8 projected over the conveyer 1 in response to an operation signal is disposed adjacent to the plate 6 on the sheet S going side, and rotors 10 which are provided with a plurality of support arms 12 radially arranged and are intermittently turned outwardly each other are disposed on both sides below the hopper 9. In the thus constructed apparatus, a sheet S transported by the conveyer 1 is stopped below the hopper 9, raised by the plate 6 and sequentially stacked in the hopper 9 by the support arms 12 of the rotors 10. Thus, a fixed interval is kept between the stacked sheets and the following sheet to be stacked so as to prevent damages of the sheet.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stacking device for PTP sheets in a conveyance line for the sheets.

pTp, f na wachi breath through punking (Press
Through packing is generally done by continuously heating a thermoplastic film and molding it using vacuum or compressed air to place the tablet into a molded pocket.

This is a packaging method in which capsules are filled, a sheet of aluminum foil or the like is heat-bonded on top of the capsules, and the capsules are trimmed to the desired size. ``FTP'' is a general term for both continuous notes created by the PTP method and individual trimmed sheets, and in the present invention, I) T.
The P sheet is intended for the latter individual 7-1.

In the PTP method, continuous FTP sheets are trimmed to become individual FTP sheets, which are continuously conveyed by a conveyor at appropriate intervals, which are piled up in a stacking device to form a batch, wrapped in plastic, etc., and sold as products. A production line has been implemented.

In such a production line, the PTP sheet is
FTP sheets are sent from the manufacturing equipment to the stacking equipment via the inspection conveyor, but if the stacking equipment stops for some reason, the FTP sheets are sequentially stacked and stocked on the PTP sheet stacking machine installed after the inspection conveyor. It also has a buffer function.

By the way, in the conventional FTP sheet stacking device, the FTP sheets conveyed by the conopear are stopped under the hopper, and the stacking plate is raised from below to be stacked in the hopper one by one, but the number of stacked FTP sheets is When increasing (e.g. 5
(0 to 100 sheets), the entire weight of the PTP sheets stacked up to that point will be applied to the next PTP sheet to be stacked, and the stacking plate will rise rapidly, causing scratches on the PTP notes and causing damage to the product. often significantly reduces value,
Early improvement was hoped for.

The present invention was made in order to solve the above-mentioned conventional problems, and it supports the stacked FTP sheets with a support and always maintains a constant distance between the stacked FTP sheets and the next FTP sheet to be stacked. F stacked while maintaining the spacing
The object of the present invention is to provide a stacking device that is configured so that the weight of the TP sheets is not increased, thereby eliminating the risk of damaging the PTP sheets.

PTP sheet pruning device according to the present invention? In order to achieve the above purpose, the FTP7-) is equipped with a hopper installed above the conveyor where FTP7-) is conveyed, a stacking plate placed below the core popper and moved up and down by actuating CI4, and a stacking plate. The FTP sheet is placed on the side facing the advancing side and is moved to the upper part of the conveyor by an activation signal.
A stopper that protrudes from the hopper, and a rotor that is provided on both sides of the lower part of the hopper and has a plurality of radially supporting arms and rotates intermittently outward from each other, and the rotor is configured to hold the FTP sheets sent by the conveyor. It is characterized in that the materials are stopped below the hopper, raised by the soil stacking plate, and successively stacked in the hopper by the support arm of the rotor. The present invention will be explained below using the drawings.

FIG. 1 is a side view of an embodiment of the present invention, FIG. 2 is a front view thereof,
FIG. 6 is an enlarged sectional view taken along line 1-1 in FIG. In the figure, 1 is a conveyor for FTP sheets (hereinafter referred to as sheets) S, and the figure shows a round belt 2 suspended from pulleys 4. 5 is an air cylinder for stacking, and a stacking plate 6 is attached to its operating rod. 7 is an air cylinder for a stopper, 8 is a stopper attached to its operating rod, and 9 is a hopper arranged on the stacking plate 6 at a predetermined interval. Note that FIG. 2 shows a case where two stacking devices are installed in parallel.

Reference numeral 10 denotes a rotor provided on both sides below the hopper 9, and six support arms 12 are provided radially around the rotor 11 at intervals of 60°. Number 1 is an intermittent drive mechanism. In the intermittent drive mechanism 16, 14 is a ratchet having notches on its outer circumference consisting of steep slopes and gentle slopes at intervals of 600 mm, and its +11t 15 is connected to the shaft 11 of the rotor 1U.

16 is a holder for a ratchet pawl, 17 is a through hole provided in this holder 16, and ratchet pawls 19 are slidably inserted into the through hole 17 on both sides with a spring 18 in the middle;
The holder 16 is connected to the operating rod of the air cylinder 20 via a member. Reference numeral 21 denotes a reversal prevention spring for the ratchet 14.

Next, the operation of the timing raising device configured as described above will be explained. Normally, the stopper 8 is not operated and is located below the conveyor 1, and the 7-tooth S is conveyed by the conveyor 1 and is recessed into the next process and stopped. Now, when the pyrotechnic # stops, a signal is sent to the air cylinder 7, which activates and raises the stopper 8 (see Fig. 4 (a)). This is no good,
The feed of the sea) S which was sent by the conover r1 and which was -C is prevented from being fed by the stopper 8, and the hopper ? Stop directly below. 7-When the sheet S stops, the next signal is sent to the air cylinder 5, which activates it, places the sheet S on the finishing plate B, raises it, and stops at the position indicated by the broken line (see Figure 6 (B)). ).

Next, a signal is sent to the air cylinder 20, and when the operating rod is moved back and the holder 16 is pulled up, the ratchets 14 are rotated by 60 degrees in the direction of the arrows by the ratchet pawls 19, and stopped at that position by the anti-reverse spring 21. do. At this time, the rotors 10 connected to the shafts 15 of the ratchets 14 are also rotated by 60 degrees in the direction of the arrows (outward). It will be in the state shown in the figure. When /-to S is transferred to the rotor 10, the operating rod of the air cylinder 20 is moved forward again by the next message.
Lower the holder 16. When the holder 16 descends, the ratchet pawl 19 slides inwardly against each other against the spring 18, and descends along the outer periphery of the ratchet 14, and when it touches the next notch, it is stopped by the barb 18 and moved outward. It slides and engages with the notch to return to the state shown in FIG. 6. At this time,
The stacking plate 6 also descends and returns to the state shown in Fig. 1 (
(See Figure 6 (b)).

When the next 7-t S stops under hopper 9, the above and 1 [
Due to the same action, the sheet S previously stacked in the hopper 9 is further lifted by the support arm 12 of the rotor 10, and the next sheet S is fully supported by the support arm 12 (B) and rises. In this way, the /-to Ss are stacked one after another in the hopper 9, but the previously stacked sort S and the next stacked /-to S (always maintaining a constant interval, There is no possibility that the enthusiasm of the sheet S, which has been achieved previously, will be transferred to the next sheet S to be stacked. loading section
In this case, the bottom sheet S is the top layer 0)-1・11
