Description

Supply device for toothpick packing machine {a toothpick packing system}

The present invention relates to a packaging machine for automatically packing toothpicks, and more particularly, to precisely supply a toothpick stored in a hopper to a guide groove of a rotating drum and to allow the toothpick inserted in the guide groove to be stably rotated without being separated. It is about.

In general, when the toothpicks inserted into the guide grooves formed on the outer side of the rotating drum fall on the lower side of the rotating drum, they are placed on the wrapping paper that is folded and transported in a 'V' shape, and the packaging of the toothpicks is automatically made by a joining and cutting roller. The devices have already been proposed in my previously registered 'Toothpick Feeder for Toothpick Packing Machine' (see publication no. 92-2087).

However, the above-described conventional technique is that the toothpicks stored in the storage hopper are transported by their own weight along the inclined surface of the hopper and are inserted into the guide grooves formed on the outer circumferential surface of the toothpick. The use of toothpicks did not work smoothly.

In particular, when the toothpicks are transported in an unaligned state, the toothpicks are not in close contact with the outer circumference of the rotating drum and are inclined contact so that the toothpicks are not inserted into the guide grooves. There was a dissolution.

In addition, the toothpick inserted in the guide groove also has a closed end, such as being separated from the guide groove during rotation transfer, in particular, toothpicks made of starch have a greater degree of bending or torsion than the wood, so the pedestal is separated from the guide groove The frequency was high.

The present invention has been made in view of the above problems, the object of which is to ensure that the transfer of toothpicks housed in the hopper smoothly supplied to the guide groove of the rotating drum, the toothpick inserted into the guide groove during the rotation of the rotating drum It is to provide a supply device of the toothpick packing machine that can prevent the deviation and minimize the defective rate generated during the packaging operation.

Features of the present invention for achieving the above object, the toothpicks 11 accommodated in the hopper 10 is inserted into the guide grooves 21 of the rotating drum 20 is rotated and then folded in a 'V' type In the toothpick packing machine placed on the wrapping paper 30 and wrapped by the joining and cutting rollers 31 and 32, the pivoting piece 40 is arranged on the lower center of the hopper 10 and on one side of the rotating drum 20.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object is as follows.

1 to 4, the hopper 10 inclined toward the lower side is mounted on one side of the support plate (1) installed vertically, the rotating drum 20 on the other side of the support plate (1) It is constructed to be rotated under the drive of the motor.

Toothpicks 11 accommodated in the hopper 10 are inserted into the guide grooves 21 of the rotating drum 20 and then rotated and placed on the wrapping paper 30 folded in a 'V' shape to join and cut rollers 31. The upper and lower sides are joined by the 32 and are cut and packaged.

Of course, the above configurations have already been disclosed in my earlier application. However, the most important feature of the present invention lies in the rotating pieces 40 and 41 and the air suction device of the diaphragm 42 and the rotating drum 20 arranged on the support plate 1.

That is, a rotating shaft penetrating the support plate 1 is arranged below the hopper 10, and the rotating piece 40 is fixed to the rotating shaft to be rotated left and right within a predetermined radius. The pivot piece 40 is mounted at the center of the lower inclined outlet of the hopper 10 and rotated to the left and right within a radius of about 20 ° while the toothpicks 11 are prevented from tangling with each other, so that the toothpicks 11 are neatly aligned. They serve to smoothly discharge to the lower side of the hopper 10.

A diaphragm 42 is mounted below the hopper 10, and the diaphragm 42 is elastically supported by the elastic pieces 42a. The diaphragm 42 vibrates in the left and right directions to align the toothpicks 11 and to push the toothpicks 11 into the guide grooves 21 of the rotating drum 20.

A rotating piece 41 penetrating the support plate 1 is also formed on one side of the rotating drum 20 to be rotated within a predetermined radius. The rotating piece 41 also rotates left and right, and serves to push the toothpicks 11 transferred by the diaphragm 42 into the guide grooves 21 of the rotating drum 20.

An eccentric cam 50 is installed on one side of the lower side of the support plate 1 to rotate under the power of the motor 50a, and a pair of rings (front and rear) of the eccentric cam 50 penetrates the support plate 1. 51 and 51a are inserted respectively.

The ring 51 and the diaphragm 42 mounted in front of the support plate 1 are connected to each other by a link 52 for connection. Therefore, the rotational force of the irregular ring 51 generated by the eccentric driving force generated when the eccentric cam 50 is rotated is transmitted to the diaphragm 42 to vibrate the diaphragm 42.

In addition, the rotary shafts of the ring 51a and the rotary pieces 40 and 41 mounted at the rear of the support plate 1 are connected to each other by connecting links 52. Therefore, the rotational force of the irregular ring 51a generated by the eccentric driving force at the time of rotation of the eccentric cam 50 is transmitted to the rotation pieces 40 and 41 so that the rotation pieces 40 and 41 are within a predetermined angle range. It is configured to rotate left and right at.

The suction hole 22 is drilled in the outer periphery of the rotary drum 20, and the suction hole 22 communicates with both sides of the guide groove 21 through the side surface of the rotary drum 20. Semicircular ducts 23 are provided on the outside of the suction holes 22, and the ducts 23 are connected to each other by a suction pump 25 and a hose.

The present invention made of the above-described configuration, the toothpick 11 accommodated in the hopper 10 is discharged through the inclined surface of the lower tooth hopper 10 is built up in the lower portion of the hopper 10 is rotated, the right side toothpick ( 11) are aligned and at the same time discharge is promoted to be discharged to the diaphragm 42, and then the toothpicks 11 are vibrated by the diaphragm 42 to be neatly aligned and transported in the direction of the rotating drum 20, the rotating drum 20 Rotating piece 41 mounted on one side pushes the toothpicks 11 in the direction of the rotating drum 20, so that the toothpicks 11 are quickly and accurately guided by the guide grooves 21 of the rotating drum 20. It is inserted one by one.

Therefore, it is possible to increase the transfer force of the toothpicks 11 by the operation of the rotation pieces 40 and 41, and to transfer the toothpicks 11 in a neatly aligned state by the vibration of the diaphragm 42, so that the toothpicks ( 11) is accurately inserted into the guide groove 21 can minimize the defective rate generated during the packaging operation.

In addition, the suction force generated by the suction pump 25 is firmly fixed by absorbing both sides of the toothpicks 11 inserted into the guide groove 21 of the rotating drum 20 through the duct 23 and the suction hole 22. Since it is to be to effectively prevent the separation of the toothpick 11 during the rotational transfer of the rotating drum 20 has the advantage that it can be accurately supplied to the wrapping paper (30).

The duct 23 is formed in a semi-circular shape so as to be in close contact with the outer surface of the suction hole 22 to generate a suction force through the suction hole 22 only in the section in which the rotating drum 20 rotates from the lower side to the toothpick 11. ) Is fixed and supported by the semicircular guide piece 20a when the rotating drum 20 is transferred from the upper side to the lower side opposite to the opposite side.

As such, when the toothpicks 11 are fixed by suction by the suction force of the suction pump 25, the toothpicks 11 may be curved or twisted even if the toothpicks 11 are in contact with the alignment brush 60 during the rotation of the rotating drum 20. ) Is an advantage that can effectively prevent the departure. Therefore, it can be very useful for packaging of toothpicks 11, which are made of starch and have a high frequency of warpage.

The present invention as described above, the maximum transfer force of the toothpick 11 by the operation of the rotating piece 40, 41 arranged on one side of the lower center and the rotary drum 20 of the hopper 10 to the maximum. The toothpick 11 can be inserted into the guide groove 21 at the same time as the toothpick 11 can be quickly and accurately inserted into the guide groove 21 because the toothpick 11 is transported neatly by vibrating the diaphragm 42. Since the toothpicks 11 are sucked and fixed by the suction force generated by the suction pump 25, the toothpicks 11 are prevented from being separated during rotational transfer of the rotating drum 20, so that the toothpicks 11 can be accurately supplied to the wrapping paper 30. This is to minimize the defect rate that occurs during the packaging work to maximize the external competitiveness as a toothpick packaging machine.
