Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a peripheral wrapping paper folding device for a roll load, in which the cylindrical protruding portions of both edges of the wrapping paper wrapped around the periphery of a roll load (roll-shaped packaged object) to be wrapped are rolled. The purpose is to fold along the edge of the load.

A method is well known in which a roll of wrapping paper is rolled around and the projecting edges are folded in with sawtooth folding plates erected on both sides of the roll. This is advantageous in that the folding operation, which is the first step of edge wrapping, can be completed while the rolled load is being transferred from the peripheral wrapping device to the edge wrapping device. On the other hand, the range of applicable roll widths is limited by the width of the floor where the roll is transferred, and the gap between the end of the roll and the folding plate is widened to allow the roll to pass, making the folds loose. There are some problems with this. In this invention, thin grooves are provided at various places on the floor surface for roll load transfer, and the left and right folding plate support legs that protrude from the grooves under the floor are mechanically moved toward and away from each other, thereby making it possible to greatly change the width of the roll load. We also made it possible to respond automatically.

In addition, for the first time, the clamping force of the rolled load by the folding plates on both sides can be maintained and adjusted at a constant value by controlling the torque of the powder clutch. As a means to increase the roll load propulsion force in response to the clamping force and reinforcement, we also propose a mechanism in which both ends of a push rod spanning the width of the floor are driven by a chain conveyor, and the propulsion means does not change even when the roll load dimensions change. First, to give an overview of the present invention, it has a width wider than the roll load with the maximum width, a length in the turning direction necessary for folding the wrapping paper of the roll load with the maximum diameter, and a length approximately perpendicular to the turning direction. A roll load transfer floor having a plurality of floor grooves cut into the floor, a mechanism for pushing and rolling the roll load on this floor in the above-mentioned transfer direction, and a transfer row 5.
Stand on the floor with both ends of the rolled material in between, and insert the left and right sawtooth-shaped folding plates into which both ends of the wrapping paper are folded in. , a support leg that maintains the posture of the folding plate by engaging with a gap adjustment rail along the floor groove, a drive mechanism that directly or indirectly drives this support leg along the rail, and included in this drive mechanism, This peripheral wrapper folding device for roll loads is characterized in that it is equipped with a magnetic powder clutch that makes the roll clamping force of the left and right folding plates constant and adjustable during folding.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of an embodiment of the present invention, and FIG. 2 is a side sectional view thereof.

R indicates the maximum and minimum dimensions of the roll load. The main parts are
A roll shifting floor 1, as a mechanism for pushing the rolling load R on this floor 1, a push rod 2 that crosses the shifting floor 1 at a right angle at a constant height and pushing and rolling the rolled load R on the floor;
a chain fitting 3 and an idler wheel 4 attached to each end of the chain, a circulation chain 5 attached to the attachment 3, and a track 6 for guiding the idler wheel 4.
, and stand on one floor so as to sandwich both end surfaces of the rolling load R, and hold the left and right sawtooth-shaped folding plates r for folding both ends of the wrapping paper on the circumferential surface of the roll, and the floor of the left and right folding plates γ, respectively. Groove 1
A rail 9 and a drive mechanism 10 that cause the support legs 8 protruding from the floor from a to approach and separate from each other, included in this drive mechanism 10,
These are magnetic powder clutches 11 and the like that keep the rolling load R clamping force of the left and right folding plates constant and adjustable. The roll transfer floor 1 is flat and has a horizontal force/slight slope for promoting transfer.

Its width is sufficient to carry the widest roll load, and its length is longer than the circumference of the roll load with the largest diameter. The length of the folding plate r is also longer than the floor length, and the shape of the serrated folding piece is left to the well-known skill of the designer. Since the conventional folding plates r are provided on both sides of the rolling bed 1, it is not possible to handle rolled loads having a width narrower than the bed width.

Therefore, the inventor of the present invention has created a system that greatly increases the adjustment range of the folding plate interval according to the roll load width by dividing the floor into left and right halves, leaving a gap between them, and fixing the folding plates to the outside of the left and right floors. is being developed. However, in that case, there was a risk that the roll load would fall between the left and right floors due to clumsiness and cause damage. In this invention, the floor width is made sufficiently wide, and the folding plates R and T standing on the floor can be freely adjusted in interval along the groove 1a that crosses the floor 1 as described above.

The grooves 1a are narrow grooves that do not affect the movement of the roll load R. In the embodiment shown in the figure, two narrow grooves are lined up, and the two vertical plates that have passed through each are fixed to a horizontal plate to serve as support legs 8. There is. An above-the-floor portion of the support leg 8 is formed by connecting the above two vertical plates with a plate to form a bracket portion 8a, to which a folding plate r is attached via a spacing member 8b. The mounting hole is an elongated hole so that the vertical position of the folding plate r can be adjusted. Four wheels 8d of the chassis 8C1 are attached to the lower surface of the support leg 8, and the chassis 8C1 can be moved along a rail 9 that crosses under the floor.

The reason why four wheels 8d are provided is to receive the bending moment of reaction force when the end face of the roll load 1 is pinched by the left and right folding plates R, r. However, these structures are left to the designer. Two or more support legs 8 are attached to the folding plate r on one side.

The interval between the folding plates r may be adjusted by directly driving the chassis 8c of the support leg 8, but in this embodiment, a driving plate 12 is attached to the folding plate r adjacent to each support leg bracket portion 8a. ing. A chain 10a of a drive mechanism 10 is attached to a portion of this drive plate 12 that comes out from another floor groove 1a to under the floor. One chain 10a is attached to one drive plate 12, and two chains 10a are attached to one drive plate 12.
is moved by one drive shaft 10b, so the folding plate r moves in parallel. The drive mechanism 10 shown in FIG. 2 may be attached to each of the folding plates r on both sides, or the drive mechanism 10 of FIG.

The surface of the floor 1 is smooth, and the roll load R placed thereon moves easily when its end face is pushed by the folding plate r. In the above implementation, since the folding plates R and r on both sides approach each other symmetrically, the roll load R is accurately pinched at the center of the floor 1. In order to use this embodiment device, as is well known, the roll load R, which is wrapped with wrapping paper and has both edges protruding into a cylindrical shape, is placed at the starting point on the floor 1, at the position R on the left side of Figure 1. I'll put it on. Then, the motor 10c of the drive mechanism 10 is started, and the magnetic powder clutch 11, the speed reducer 10d, and the drive shaft 10b are interposed between the motor 10c and the chain 10a that converts the rotation into linear motion along the rail.
1 chain 10a11 The folding plates r on both sides are brought close to each other by the driving plate 12, and the rolled load R is pressed from above the wrapping paper which has been folded up in advance only at the portion where the folding plates r contact. When the clamping force reaches a desired value, the control section of the magnetic particle clutch is adjusted in advance so that the magnetic particle clutch slips while maintaining the torque that maintains it. Next, the push rod drive motor 13 on the frame frame 14 is activated to rotate the conveyor drive shaft 15.

This shaft 15 spans between the left and right columns of the frame frame 14 on the end side of the floor 1. Chain wheels 16 attached to both ends of this shaft 15
Two pieces connect the circulation chain 5 and chain wheel 16a on each side,
Drive. As shown in FIG. 1, the one-side chain 5 is guided and driven by the vertical guiding chain wheels 16a, 16a on the starting point side and 16, 16a on the terminal end side. The push rod 2, which has the chains 5, 5 on both sides locked via the chain fixture 3, has its idler 4.
The roll load R is moved in parallel along the guided track 6 to push the roll load R from the position shown in FIG. 1 to the position 2. Since the outer tube 2a of the push rod 2 is rotatably fitted onto the core shaft, even if the outer tube 2a rotates due to the rotation of the roll load R, it does not affect the chain fixture 3 fixed to the core shaft. Further, since the outer cylinder 2a is thicker than the core shaft, it rotates lightly when the roll load R is transferred, so there is an advantage that the surface of the roll load R is not damaged. Of course, the outer cylinder 2a and the core shaft may be fixed as long as the engagement portion between the chain fixture 3 and the two core shafts of the push rod is made rotatable. When the push rod 2 pushes the roll R from the starting point to the end of the floor 1 and reverses it upwardly, the roll R whose both edges of the circumferential wrapping paper have been folded is pushed out from between the folding plates r and proceeds to the next step.

Then, a new roll load R enters the starting point, and the push rod 2, which has returned to the starting point after rising and reversing, advances the roll load R, which is automatically repeated. Although one embodiment has been described above, the present invention can be modified depending on the design conditions without changing the gist of the invention.
Needless to say, it can be varied in various ways depending on the designer's known technology. In this invention, since it is necessary to change the interval between the folding plates according to changes in the width of the roll load, it is possible to
The conventional technology of placing only both edges on the floor and transferring the roll has been abandoned, and instead a floor with sufficient width is used, eliminating the possibility of roll loads falling off.

Since the folding plate is operated under the floor through a narrow groove that crosses the floor,
The interval between the folding plates can be narrowed as desired, and the drive mechanism is housed under the floor, making effective use of the factory floor.

In addition, in the past, the folding plate spacing was determined by the experience and force of the operator, which tended to loosen the folds of the wrapping paper, but by using a magnetic particle clutch, a constant clamping pressure with a constant torque is applied to the end surface of the roll evenly. Since the wrapping paper is pressed against the edges, the folds in the wrapping paper are better than in the past, and the quality of the folds does not fluctuate.

Further, the clamping force can be easily adjusted by operating the magnetic powder clutch control section. Furthermore, if the push rod of the above embodiment is used, the push rod, which can always push the maximum width of the roll load, is powerfully driven by the left and right chains, so that when the size of the roll load changes, the operator has no need to make manual adjustments like in the past. no longer needed,
Since it lifts and reverses, it is suitable for continuous work, and it is easy to attach multiple push rods to the chain.

Due to the strong thrust, the folding plate can be rolled without any trouble even if the roll clamping force by the folding plate increases, so that the folds can be made stronger than before. This invention is the culmination of the inventor's research and experience as a circumferential wrapping paper folding device for rolled loads, and has achieved great effects in terms of safety, finish quality, productivity, and ease of operation.
