Abstract

PURPOSE:To reduce the cost of operation, by setting up a cap passing monitor mechanism at a cap feeding passage, while controlling the cap feeding capacity so as to bring it down when caps in a row stand in the way in the monitoring region. CONSTITUTION:When trouble happens in operation by a capping applicator 3 and thereby a one-piece feeding motion is stopped, caps are stayed up to the monitor region of paired monitors 4. In consequence, since a light beam from a luminous element E of the paired sensors 4 is shut down beyond a time t commensurate to the cap consumption rate, drive signals from a delay circuit are generated so that a parts feeder 1 is switched from high voltage excitation to low voltage excitation, lowering its feed capacity; cap feeding from the parts feeder 1 is thus virtually stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cap supplying device for supplying a cap to a capping applicator used, for example, in the production of films containing cartridges.

Generally, capping is performed by a cap supplying step of supplying a cap to a capping applicator and a capping step (2) of fitting and mounting a cartridge body member cap on the capping applicator.

Therefore, in order to perform capping at a low cost, a capping applicator that performs capping in succession has been developed, but in order to not lose the features of this capping applicator, it is necessary to It is required to use a feeding device that can reliably feed the cap, and for this reason, a vibrating parts feeder or the like is used to feed the cap at a rate higher than that consumed by the capping applicator, so as to maintain a constant vortex feeding state. I'm trying to get it.

However, in this series of processes, there are often cases where the capping applicator must be stopped, such as when the cap or ballone body member contains a defective material and the required killing cannot be performed. However, there is a disadvantage that there is a surprising amount of unnecessary force being generated by the parts feeder while the parts feeder is stopped.

The present invention has been made based on the above circumstances, and provides a cap feeding device that can reliably feed caps to a catting applicator (8) and has low operating costs. The purpose is to

Its special features include a cap feeding mechanism that feeds the cap to the capping applicator along the feeding path, a monitoring mat that monitors the J[IJ error of the cap in the feeding path, and a monitoring chain line of this monitoring mechanism. The present invention further includes a cap supply control system that reduces the supply capacity of the cap mechanism when the sent caps are retained.

The present invention will be explained below with reference to the drawings.

FIG. 1 shows a cap feeding device that feeds caps to capping applicators used for manufacturing film containing cartridges, and reference numeral 1 denotes a vibrating parts feeder (hereinafter referred to as "parts feeder") constituting a cap feeding mechanism.

), a tray portion 11 for accommodating the caps is formed in the upper part of the parts feeder 1, and a spiral feeding hPl for feeding the caps in a row is formed on the inner surface of the tray portion 11. It is formed. At the tip of this feeding W8P1,
? Wet oqss-z22to (2) Connect an inclined feed path P2 consisting of a chute 2° inclined downward and equipped with one feed mechanism (not shown) on the downstream arm. This chute 2 constitutes a feeding path Ptt together with the spiral feeding path PI, and the cap from its discharge port is received by a cap holder 81 forming a capping abject IJ container 8.

The cap holder 81 is provided on a gate-shaped rotating support frame 82 that rotates around a rotation center After being rotated sideways to fit and attach the cap in the cap holder 81 to the cartridge chest member located in front, it is returned to its original position and ready for the next capping.

Behind the spiral feeding path P1 following the plate s11 in the parts feeder 1, a reflective photoelectric sensor 6 and an air nozzle 7 are connected to the feeding path through holes 61 and 71 formed in the feeding path member related to this feeding path P1. The cabs are installed in this order along P1. 1. A photoelectric sensor 6 (5) determines whether the inside is the inside or the inside is determined by the difference in the paint color between the front and back sides, and the pressurized air flow from the air nozzle 7 is selectively injected only to the caps that are not in the required condition. I try to blow it off. In addition, the cap II! As a means for feeding the air in a large amount, the photoelectric sensor 6 is not used, and the air nozzle is directly opposed to the spiral feeding path P1 at an appropriate angle, and the cross section of the scarcity part and the center hole part related to the fitting part of the cap is Utilizing the fact that the state of resistance to the air flow depending on the shape is different between a face-up cap and a face-down cap, only the cap facing the wrong orientation may be blown off from the feeding path P1.

The chute 2 in the feeding path P has side walls 21°21'
A long hole 2 extending in the length direction in the center of the ! , 22' are formed to face each other, and in the middle of this chute 2,
For example, the elongated hole 22 is configured to monitor the passage of the cap.
．． A pair of sensors 4 consisting of a light emitting element E and a light receiving sensor S facing each other via 22' are provided to constitute a monitoring mechanism. Here, the above-mentioned emitter yt, element E, and light receiving sensor S are installed at position u1, and in the width direction of chute 2, they are loosely matched. 6) The set optical axis passes through the passage level of the center hole of the cap. Also, regarding the steep direction of the chute 2, the same light beam is blocked from the light emitting cord E to the light receiving sensor S by the collar of the stopped cap when the cap is retained.

A cap supply control system is connected to the pair of sensors 4 constituting the monitoring mechanism, and this cap supply control system reaches the light receiving sensor S from the light emitting element E through the center hole of the cap, as shown in FIG. After receiving a signal indicating that the light beam has been interrupted, one cap corresponds to the consumption rate of the cap by the normally operating capping applicator 8, i.e., It includes a delay circuit (not shown) that issues a drive signal when the above-mentioned light beam is still blocked even after the time t required to pass through the monitoring area, thereby detecting a delay in cap feeding. , the driving section 414 lowers the supply capacity of the parts feeder 1 by exciting it with a low voltage, and when the light from the light emitting element E is not blocked for a time period te (7), a drive signal is sent from the delay circuit. It has a function of bringing the supply capability into a normal state by exciting the parts feeder 1 with a high voltage without generating any noise.

In an embodiment with such a configuration, the parts feeder 1
Photoelectric sensor 6 and air nozzle 7 among the caps
Due to the action of IWM from the feeding path P by the pulp feeder
The cap holder 81 of the capping applicator 8 is supplied to the capping applicator 8 to be fitted into the body member.

When the capping applicator 8 is operating normally, the cap does not stay in the monitoring area related to the sensor pair 4, so the driving side signal is not output from the delay circuit of the cap supply control system. The parts feeder I is therefore placed in a normal operating state.

If a problem occurs in the capping by the capping applicator 8 and the feeding operation of the one-piece feeding mechanism is stopped, the caps stay in the chute 2 up to the monitoring area of the sensor pair 4, and the light emitting element E of the capping sensor pair 4 is stopped. The light beam from the time t depends on the consumption rate of the cap.
cap supply control I.
A drive signal is issued from the delay circuit of the system, and as a result, the parts feeder 1 is switched from high voltage excitation to low voltage excitation, reducing its supply capacity, and as a result, feeding of caps from the parts feeder 1 is effectively stopped. be done.

Then, when capping by the capping applicator 8 is started again and the one-piece feeding mechanism starts the feeding operation again, the caps arranged in the chute 2 are sequentially moved downward due to their own weight according to the operation of the capping applicator 8. As a result, the light beam from the light emitting element E reaches the light receiving sensor S, so that the supply capacity of the parts feeder I is returned to its original normal operating state by the supply system.

Accordingly, in the present invention, the jealousy plate and cap supply 1
171I- system, when caps accumulate in the feeding path P, the cap supply lll1$1, for example, the supply capacity of the parts feeder 1, is reduced.
When a problem occurs in capping with the capping applicator 8, when the feeding operation of the one piece feed 1M misfortune is stopped in step 4, that is, when the feeding operation of the cap feeding mechanism is not required, the feeding operation of the cap feeding mechanism is stopped. Since the capacity will be reduced, the cap supply ms
Since a large amount of power is wasted in the process, significant energy savings can be achieved, and the cap supply device's $il! In addition to being able to reduce labor costs,
When the operation of the capping applicator 8 returns to its normal state, the supply capacity of the cap supply mechanism is restored. Therefore, when the capping applicator 3 is operating normally, the capping applicator 8 can be reliably supplied at all times (10). It is possible to supply caps to customers and perform the required capping work with high work efficiency. In order to reduce the supply capacity of the cap supply S structure, the drive source is not completely stopped, but is brought into operation to the extent that cap feeding is virtually stopped, thereby reducing the supply capacity when starting feeding again. The start-up can be made faster.

In addition, in the present invention, feeding 1? Two pairs of sensors each consisting of a light-emitting element and a light-receiving sensor are provided along the IP, and these pairs of sensors are installed in the same positional relationship as the pair of sensors 4 both in the width direction and the handle direction of the chute 2. A signal indicating that the light beam 1 has been irradiated to the light receiving sensor of one of the pair of sensors located on the downstream side of the feeding path P is received, and from the time the signal is received, one cap is consumed according to the consumption rate of the cap. When the light beam continues to be irradiated even after the cap has stopped in the monitoring area for a period of time Tt, a station that emits a drive signal to excite the Sophida 1 with a high voltage. The delay circuit for voltage excitation and the light receiving sensor in the other pair of sensors located on the upstream side of the feeding path P receive a signal indicating that a potential beam has been irradiated, and from the time the signal is received, the cap is moved. When the light beam is still interrupted even after the time t required for parts feeder 1
A low-voltage excitation delay circuit that generates a drive signal for low-voltage excitation may be incorporated into the cap supply control system. By energizing the parts feeder 1 with a high voltage and energizing the parts feeder 1 with a low voltage using the other pair of sensors, the operation of the cap supply control system can be ensured, and Its construction can be made simple. Furthermore, in such an embodiment, if one pair of sensors is arranged in the steeply sloped chute 2 near the capping applicator 8, when the operation of the capping applicator 8 is restored, ?

When installing one pair of sensors located on the downstream side of the feeding path P, it is necessary to ensure that the number of caps retained up to the cap holder 81 is such that it does not interfere with continuous operation by the capping applicator 8. In addition, when installing the other pair of sensors located on the upstream side of the feeding path P, it is necessary to make intermittent replenishment possible in order to stably maintain the retention state up to the one pair of sensors. Specifically, the consumption speed of the cap in the capping applicator 8,
The position of each pair of sensors is determined by the feeding speed of the Iγ-feeder 1, etc.

As described above, according to the present invention, it is possible to provide (18) a cap supplying device that can reliably supply a cap to a capping applicator and has a low operating cost.
