Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a turret-type feeding device for packaging base paper, and particularly relates to a turret-type feeding device for packaging base paper, and particularly for paper that is large and heavy, such as coiled steel plates, and has a large diameter and surface length. The present invention relates to a turret type base paper supply device suitable for use in automatic packaging of cylindrical bodies of various sizes.

(B) Prior Art A large and heavy cylindrical object to be packaged, such as a coiled steel plate, is a hollow cylindrical body, so in order to completely package it, the inner circumference, outer circumference, and both 4A sides must be wrapped. . For wrapping the inner and outer peripheries, the width of the wrapping paper must be changed depending on the surface length of the cylinder.

Therefore, if coil steel sheets of various sizes are to be assembled along one conveyance line, several types of packaging paper rolls must be prepared on this conveyance line.

The apparatus previously developed by the applicant for automatically packaging large and heavy items had an inner wrapping position, an outer wrapping position, an end wrapping position, etc. arranged in tandem along a linear conveyance line. In such a device, the inner or outer wrapper is set at the center of the conveyor line, and the wrapping paper must be fed to this fixed position.

Therefore, a large number of packaging base paper roll groups are stored in parallel along the conveyance line in the ceiling space above the conveyance line.

However, although this ceiling storage method has the advantage that each roll of base paper is placed above the head of the cylindrical body to be wrapped, making it easy to align the center lines of each other's widths, the rolls of base paper, which are quite large and heavy, are stored in the ceiling space. In addition to the enormous amount of effort it takes to lift it up, and the difficulty of installing and adjusting it at a high place, there is also the drawback that the relatively limited ceiling space limits the number of rolls of base paper that can be stored.

Furthermore, the packaging base paper pulled out from each roll passes through each path and is finally guided to a supply port located at a fixed position on the object to be packaged. Since there is only one supply port, it is necessary to constantly switch connections between multiple routes and the supply port, but the mechanism and operation for this switching is complex. Because the lengths of the paths to the feed ports at different locations are not the same, the web of paper drawn from a roll of paper at a far location may sag or become misaligned along the way, and the response to switching operations may be delayed, resulting in a delay in the delivery of the desired base paper. The only drawback is that the amount cannot always be maintained accurately.

Therefore, in the patent application related to Japanese Patent Application No. 58-252130, the present applicant proposes that [A toroidal body rotatably supported along the circumference of the toric body, which is rotatably supported in a vertical plane, A large number of base paper supply sources are installed, each consisting of one base paper roll, a foot roll that pulls out the base paper web from the base paper roll, and a guide plate that guides the pulled out base paper web to the outer periphery of the ring. A web discharge position is provided at a constant height along the outer circumference of the stop, and by rotating the torus, the guide plate of any one supply source is aligned with the discharge position so that any base paper web can be discharged. Turret type base paper feeding device. ” was disclosed.

However, with this system, it was inconvenient to replace the base paper roll.

(C) Problems to be Solved by the Invention The problems to be solved by the present invention are to improve the structure of the device disclosed in the aforementioned patent application filed by the applicant, to facilitate the exchange of base paper rolls, and to The object of the present invention is to provide a turret type base paper supply device that can also measure the amount of paper supplied.

B) Means for Solving the Problems The turret type base paper feeding device of the present invention comprises a pair of parallel disks spaced apart from each other at a predetermined distance, and a A base paper supply unit that is attached along the side and consists of a base paper roll, a feed roll, a guide roll, and a cutter, a support roll that supports the disk vertically and rotatably, and a center of the pair of disks a first drive motor connected to mutually connected central shafts to rotationally drive the disk; and a second drive motor selectively connected to and detachably connected to the feed roll to rotationally drive the feed roll. By means comprising a motor, a measuring mechanism that is selectively connected to the feed roll in a detachable manner to measure the rotational speed of the feed roll, and a stopper mechanism that holds the disc at a predetermined angular position. This solves the above problems.

((E) Embodiment 1 A turret-type base paper supply device of the present invention will be explained with reference to FIGS. 1 to 6. This device consists of a pair of discs 1.A base paper supply unit 2, , a first drive motor 4, a second drive motor 5, a measuring mechanism 6, and a stopper mechanism 7.

A pair of discs 1 are fixed to a central axis 11 parallel to each other with a predetermined interval. In order to reduce the weight of the disc 1, it may be formed into a wheel shape as shown in FIG.

The base paper supply unit 2 includes a base paper roll 21, feed rolls 22, 22 . It is made up of a guide roll 26 and a cutter 24. Each element is supported rotatably across the disk 1. A plurality of units 2 are provided along the circumference of the disk 1. In each unit 2, the base paper P is unwound from the base paper roll 21, passes through a guide roll 26, a cutter 24, and is sandwiched between a pair of feed rolls 22.

One pair of support rolls 6 are provided at intervals between the disks 1.

The support roll 3 is rotatably supported by a bearing 61. The support roll 6 supports the disc 1 vertically and rotatably.

The support roll 6 supports the weight of the entire device and the disk 1 described later.
Depending on the structure of the drive mechanism, one of the pair of rolls (for example, the right or left roll in Figure 2)
can also be omitted.

The first drive motor 4 and the second drive motor 5 are fixed on a support base 8, as best shown in FIG. One end of the center shaft 11 is rotatably supported by the bearing stand 9, and the other end of the center shaft 11 is connected to the first drive motor 4. 1st
When the drive motor 4 operates, it rotates the central shaft 11'lr, and as a result, the disk 1 is rotated.

The second drive motor 5 is fixed to a sliding base 51 that slides on a support base 8, as shown in FIG. The slide 51 is moved forward and backward by a hydraulic cylinder 52.

One of the pair of feed rolls 22 serves as a drive roll. As shown in FIG. 5, a coupling 221 is attached to one end of the central shaft of the feed roll 22. As shown in FIG.

When the disc 1 is rotated and reaches the position of the second drive motor 5, it is stopped by a stopper mechanism 7, which will be described later. The second drive motor 5 is moved forward, and the coupling 56 attached to the tip of its output shaft frictionally engages with the coupling 221 .

As shown in FIG. 5, a measuring mechanism 6 is provided facing the second drive motor 5 with the disk 1 interposed therebetween. Counting mechanism 6
is a counter 61, a sliding table 62. It is made up of a hydraulic cylinder 66. The slide table 62 is slidably supported on the bearing stand 9 and is moved forward and backward by a hydraulic cylinder 63. A counter 61 is fixed to the sliding table 62.

The other end of the center axis of the feed roll 22 (coupling 2
21), a coupling 222 is attached to the throat. A coupling 611 is connected to the input shaft of the counter 61. It is set so that when the couplings 53 and 221 at one end are engaged, the couplings 611 and 222 at the other end are engaged. That is, feed roll 2
2 is being driven by the second drive motor 5, a counter 61 counts its rotational speed or feed amount.

The second drive motor 5 and the counter 61 may be attached to all of the feed rolls 22 on the drive side. In that case, the necessary second drive motor 5 and counter 61 are set to be selectively activated when the feed roll 22 comes to a predetermined angular position.

A stopper mechanism 7 is provided to stop the disc 1 at a predetermined angular position at a predetermined pitch. For example, as shown in FIG. 6, holes 12 are provided in the disk 1 corresponding to the circumferential pitch of the feed roll 22, and the tip 72 of the piston rod of the body pressure cylinder 71 is selectively inserted into the holes 12. Constructed so that it can be engaged and detached.

Returning to FIG. 1 again, the desired base paper P is taken out from the base paper take-out position A, and cutter C or 24 is used for each required length.
-1.

(F) Function The maillet type base paper supplying device of the present invention determines all the rolls of base paper to be supplied in accordance with the request from the final use site as described above, and selects the particular roll, for example, 2l-1e base paper take-out position A. The disk 1 is rotated by the first drive motor 4 so as to move it. A stopper mechanism 7 holds the disc 1 in that position.

The coupling 53 of the second drive motor 5 then engages the coupling 221 of the feed roll 22-1 and drives that feed roll. At the same time, coupling 611 of counter 61 engages coupling 222 of feed roll 22-1. As a result, the feed roll 22-1 is rotationally driven, and the amount of rotation is measured by the counter 61.
It is weighed by.

The feed roll 22-1 is rotated by a predetermined amount, and a required length of base paper P is fed out from the base paper roll 21-1, and the guide
It is guided to the outside of the disc 1 through the roll 26-1. If the above-mentioned relay body is waiting there, for example, the leading edge of the raw paper P to be fed out is temporarily wound around the temporary winding roll of the relay body, and the rear end of the raw paper P is cut at a predetermined length by a cutter C or 24. -1
It can be cut by. The cutting time is determined based on the display of the counter 61.

(g) Effects According to the present invention, for a large number of base paper supply sources, the path from the base paper roll to the base paper outlet A is relatively short, and
Since the length is the same and a feed image roll is always provided for each such short path of the same length, packaging base paper of the required length can be reliably supplied from any base paper roll with the same reliability. Therefore, it is ideal as a base paper supply source for automatic packaging processes.

In addition, since the feeding device of the present invention is a turret type that can rotate in a vertical plane, it requires less installation space and can be used in a much wider variety of products compared to a flat arrangement such as a ceiling storage type. It is possible to easily store rolls of base paper.

The device of the present invention is stable because the lower part of the outer periphery of the disk is supported by a support roller, and the central axis of the disk is supported by a bearing stand, and the front side that is received by the support rollers is open. This makes operations such as loading the base paper roll and adjusting the 5 devices for web feeding extremely easy and safe.

Furthermore, unlike ceiling storage systems, the turret is installed on the floor, so multiple pairs of disks can be added in parallel if necessary, allowing for additional paper supply sources without modifying the packaging line itself. By diversifying, the processing capacity of the packaging line itself can be increased and improved.
