Description

[Detailed Description of the Invention] Industrial Application Field The present invention is for temporarily storing the solids sent sequentially from the previous process, and bundling the solids accumulation when the solids are accumulated to a predetermined number. The present invention relates to a binding machine.

Conventional technology A predetermined number of bags (for example, 1) are sent sequentially from a bag making machine.
When tying bags in units of 00 sheets), the bag making machine and the tying machine are placed close together in the factory, the bags are temporarily stored in a holder installed at the exit of the bag making machine, and a counter is attached to the holder. In addition to counting the number of bags, a signal is emitted when the number of bags reaches a predetermined number, and based on that signal, a worker waiting near the exit of the bag making machine switches the holder. (Depending on the bag making speed at which the accumulated bags are taken out, the accumulated bags may be taken out without switching the holder) and then fed to the binding machine.

Problems to be Solved by the Invention This method has been widely used in the past, but since it takes a relatively short time for a predetermined number of bags made by a bag making machine to be stacked in a holder, At the exit of the bag-making machine, a worker must be stationed at the exit of the bag-making machine to transfer the material to the binding machine. The fact that a dedicated worker is required to transfer bags from the bag-making machine to the binding machine is a big disadvantage in terms of labor-saving.

Moreover, considering that workers sometimes leave the site for a few minutes for short tasks, it is necessary to assign a replacement worker in advance, call another worker, or temporarily stop the equipment. You have to choose one.

In addition, when the counter attached to the holder notifies that a predetermined number of bags have been accumulated, it is necessary to immediately replace the holder or take out the bags that have accumulated in the holder, but the worker loses the timing. Sometimes,
As a result, there may be an excess or deficiency in the number of products bundled, or the number may have to be checked again.

These problems arise because bag making machines and binding machines are manufactured for different purposes, such as a bag making machine is a bag making machine and a binding machine is a binding machine, and the coordination between the two is not sufficient. is based on the fact that it is not taken into account.

The binding device disclosed in Japanese Unexamined Patent Publication No. 62-28313 filed by the present applicant is a device for automatically binding objects to be bound using a heat-fusible tape. When a predetermined number of individuals are accumulated and then tied together, the above-mentioned problems inevitably occur.

The present invention was devised from an attempt to provide a binding machine with a function of accumulating a predetermined number of pieces sequentially sent from the previous process.

Means for Solving the Problems The binding machine of the present invention is capable of binding objects (
This is a binding machine that once stores the solids (p) and then bundles the collected solids (p) when a predetermined number of solids (p) have been accumulated. Individual accumulation holders (2) are provided at predetermined intervals, and the tape supply section (3) is on one side of the running surface of the transport means (1), and the tape take-up section (0) is on the other side. are arranged so that the binding tape (1) stretched between them is directed in a direction substantially perpendicular to the traveling direction of the conveyance means (1), and furthermore, the binding tape (1) is stretched at a position A sealing means (5) that reciprocates in a direction substantially parallel to the tensioning direction of the binding tape (1) is disposed at a position on the advancing side of the conveying means (1) close to the binding tape (1).

The present invention will be explained in detail below.

A typical example of the individual (p) that is sequentially sent from the previous process is a bag that is sent from a bag making machine.

Examples of the individual (p) include magazines, newspapers, books, vegetables, fresh flowers, pipes, hoses, wire rods, wood and bamboo materials, paper, films, sheets, labels, and webs. In this case, the pre-process equipment includes corresponding equipment such as a cutting machine, a printing machine, a folding machine, a finishing machine, and a coating machine.

In the binding machine of the present invention, a plurality of individual accumulation holders (2), -
are provided at specified intervals.

As the conveying means (1), a chain conveyor, a conveyor belt, etc. are used.

The number of holders (2) is arbitrary as long as it is 2 or more, but
Usually there are three or more. The holder (2) is often shaped like a frame.

A tape supply section (3) is disposed on one side of the running surface of the conveyance means (1), and a tape take-off section (4) is disposed on the other side. Normally, the conveying means (1) is run almost horizontally, so
The tape supply section (3) is arranged above the transport means (1), and the tape take-up section (0 is arranged below the transport means (1). In special cases, the transport means (1) may be moved in a direction other than the horizontal direction. It can also be run.

The tape supply section (3) and the tape take-up section 0) are usually a combination of a roll or reel with a guide roll as necessary, but they may also be used for supplying and taking off the binding tape (1). For example, any mechanism can be adopted.

The binding tape (1) stretched between the tape supply section (3) and the tape take-up section (4) is configured to run in a direction substantially perpendicular to the traveling direction of the conveyance means (1).

Furthermore, a sealing means (5) that reciprocates in a direction substantially parallel to the direction in which the binding tape (1) is stretched is arranged at a position on the advancing side of the conveying means (1) close to the tensioning position of the binding tape (1). do. When the binding tape (1) is a heat-adhesive tape, a fusing sealing mechanism is employed as the sealing means (5).

When the individual (p) is a bag, magazine, newspaper, etc., the individual (
p) It may be desirable to bind the stack under pressure. In such a case, the sealing means (5)
At a position on the advancing side of the transport means (1) close to the arrangement position of
It is desirable to arrange a presser means (6) for pressing the individual (p) accumulation in the individual accumulation holder (2).

When bundling individual (p) aggregates, the individual (p) aggregates are not only bound by a single thread, but also often by multiple threads. In such a case, members such as the tape supply section (3), tape take-off section (4), and sealing means (5) may be designed to cope with it.

Since the individual accumulation holder (2) has a certain height, the individuals (p) sent sequentially from the previous process are placed in the empty holder (2).
When accumulating in 2), the individuals (p) may be uneven at first due to the large head difference. In order to prevent this misalignment, an elevating fork (7) is provided on the starting end side of the conveying means (1), and the elevating fork (7) is initially placed on the upper side of the holder (2) in the position where the individual (p) is received. and temporarily receive the individual (p) there, then intermittently or i! It is desirable to continuously lower the elevating fork (7). Thereby, the drop of the individual (p) to the accumulation holder (2) is reduced.

When a predetermined number of objects (p) are stored in the holder (2) located at the object (p) receiving position, the conveying means (1) is driven to sequentially feed each holder (2) and empty holder (2). ) comes to the receiving position of individual (p). At this time, if the feeding speed of the solid (p) from the previous process is high, the solid (p) may be supplied before the empty holder (2) reaches the predetermined position. In order to avoid such a situation, a weir means (8) is provided above the starting end side of the conveyance means (1),
It is desirable that the individual (p) is retained until the individual accumulating holder (2) is positioned at the individual (p) receiving position.

Although it is possible to install either one of this weir means (8) and the above-mentioned lifting fork (7), it is preferable to install both.

As the binding tape (1), a heat-fusible tape is preferably used. The material may be arbitrary, including polypropylene, polyethylene, polyamide, polyester, and polyvinyl chloride. The tape is preferably uniaxially or biaxially stretched to improve tensile strength, but stretching is not necessary if binding strength is not so required.

It is also preferable that the tape is a tape with rubber elasticity, a so-called stretch tape, because stretch tape has an elastic recovery force, and has the advantage of exerting a tightening force after binding and preventing the binding from loosening. . In addition, self-adhesive tape or adhesive tape can also be used as the binding tape (1). The binding tape (1) can be printed with a product name, company name, trademark, pattern, etc. or colored if necessary.

The conveying means (1) that runs endlessly is provided with a plurality of holders (2) for collecting solids at a predetermined interval, so one of the holders (2) is loaded with sequentially transferred materials from the previous process. The incoming individuals (p) are accumulated.

When a predetermined number of individuals (p) (often specified in number, but can also be specified in weight) have been accumulated on the holder (2), the conveying means (1) is run by a certain pitch, and the holder The individual (p) accumulation in (2) hits the binding tape (1) stretched between the tape supply section (3) and the tape take-up section (0), and then the individual (p) accumulation Make sure that the end reaches a position beyond the initial tensioning position of the binding tape (1).As a result, the binding tape (1) is fed out from the tape supply section (3) and wrapped around the outer periphery of the individual (p) accumulation. Along〈.

Then, when the individual (p) collection reaches the above position, the sealing mechanism (5) is activated to seal and cut the binding tape (1) at the rear end side of the individual (p) collection. . As a result, the individual (p) accumulation is unified.

Note that the cut binding tape (1) is reconnected at the cut point by fusing, adhesion, or adhesive, so if the tape take-up part 0) is slightly driven, the reconnection point of the binding tape (1) will be reconnected. They are taken over by Department (4).

As the conveying means (1) travels for the above-mentioned fixed pitch, the empty holder (2) comes to the position for receiving the individual (p), so that the individual (p) accumulated in the previous holder (2) is bound. While receiving, the next holder (2) becomes the individual (p)
is in a state of accepting.

On the other hand, the holder (2
) moves forward as the conveying means (1) travels a fixed pitch, and releases the bundle during the return process of the conveying means (1).

Providing the lifting fork (7) on the starting end side of the conveying means (1) reduces the drop when the solids (p) sent sequentially from the previous process are accumulated in the empty holder (2), and (p) can be prevented from becoming irregular.

Moreover, if the weir means (8) is provided above the starting end side of the conveying means (1), even if the feeding speed of the solid (p) from the previous process is high, the empty holder (2) will be stopped before it reaches the predetermined position. M eliminates troubles such as the individual (p) being supplied.
